wires to capacitor on YORK AC unit are burned and melted
 
I thought I would get my York central AC unit repaired well before summer
hits. The unit is about 9 years old. Last year, the unit stopped cooling
but the fan still ran fine. The repair guy look at it and the wires going
from the compressor area to the capicator had melted and stopped working.
The repair guy replaced the wires and the capicator. A few months later it
happened again. A different repair from another company installed a heavy
duty wiring kit and the unit worked again for a few months then stopped when
the wires melted again.

Obviously the unit is pushing too much current through these wires. A
friend said that it might have a starter relay on top of the compression
that is not shutting off after the compresser is started. I have not taken
it apart to look.

Does this sound correct? I don't understand why the repair guys wouldn't
know this? Any other suggestions on the cause of the problem?

Thanks,

Keith

This is Turtle.

First here, If the wires [ like the whole length is melting ] is melted. You
have these things wrong with it. You have too big of a breaker to your
condenser unit or have to reset the breaker every hour or so, The wire kit
he put on it is too small, and You have a shorted out compressor somewhat.
If everything is installed correctly. You can't melt the wires.

Now secondly here. If the end only that tie on to the compressor are
melting about 1 to 3 inches back up the wire from the compressor. You have
rusted or defective terminal on your compressor and not letting the spades
connect correctly. I see this a lot on older equipment and you need a screw
on clamp wire kit. It will have a screw on clamp to tie on to each terminal
of the compressor. You buy them in sets and they will stop the burning of
the terminal off like you have. Now you have only about 3 to 6 burns off
before you burn the terminal off the compressor and then you will buy a new
compressor because you will have nothing to put the clamp on wire kit to
hold the wire on it.

Now Have the breaker / wire sized for the condenser and put a you a clamp on
wire kit on it and forget about it.

wires to capacitor on YORK AC unit are burned and melted
 
Dear Tony,
I've been posting to home repair for a couple years. I've read Turtle's
posts for several years, and he's been a real wealth of information. He's
solved problems for myself, and many others.
I'm not quite so sure about you, though. However, it is very possible
that I'm mistaken. Lets see if maybe I'm mistaken. How about you answer a
couple questions for me. I'm a rather new heating and AC tech, so here's a
great chance for me to learn.

1) You say that each of the three compressor terminals represents its own
winding. I know of two windings, but you say there are three. What are the
names of the three windings, and what do they each do?

2) What are the names of the electrical terminals on a typical compressor?
What does each terminal do?

3) In terms of temperature, what happens when a terminal is corroded, and
trying to carry current? And in terms of the electrical flow, what happens
when a terminal is corroded?

4) What is the electrical current path through a compressor? For example,
which terminal is hot, and which is neutral?

I will likely be working on condensing units this summer, and perhaps some
of your answers will help me to be a better technician.

tech....


1) You say that each of the three compressor terminals represents its own

names of the three windings, and what do they each do?


If you dont know, you are over your head already.

It sits there and sings dixie every once in a while..


3) In terms of temperature, what happens when a terminal is corroded, and

when a terminal is corroded?



Ok...you can stop with the jokes now...Mr hvac tech..


4) What is the electrical current path through a compressor? For example,
which terminal is hot, and which is neutral?


There ISNT a neutral in a compressor on a home central system moron.

No...4 years of tech school might.

There is no such thing as a shorted out compressor, somewhat. It's either
shorted out or it is not.
Keith the correct answer to your question, or at least as correct as any
observation can be using the information available and considering this is
as I always say the internet. Each of the three wires on your compressor
represents it's own respective winding in the compressor. Each, when
excessive current draw is present, indicate to a competent (dare I say that
word here), technician the correct path to follow with respect to
troubleshooting. So in order to even begin to remotely guess at the problem
one would need the information specific to which wire is carring excessive

the proximity of one to the other, there is one that is the actual carring
the excessive current. With that being said, the first thing a service tech
would do is use an Amprobe to determine the actual draw in each conductor, I
further suspect that your friends assesment is incorrect, if what he
indicated to you were true, you would get zero run time out of the
compressor, it would quickly overheat and cut out on an embedded thermal
overload-quickly, not a few days, few weeks or few months. There would also
be other indicative attributes that you have not mentioned.Since from what I
read the most educated observation that can be concluded is that the problem
is associated with the run winding, assuming the capacitor that your are
referring to is in fact the run capacitor and not the start capacitor. There
are a multitude of factors that can contribute to issues with the run
winding in the compressor. To begin with the run cap itself can be
defective, has anyone tested or replaced it? A dirty condenser coil will
increase the current draw on both the run and common windings in the
compressor, has the coil been cleaned thorughly since the issues originally
occured. For the same reason that a dirty coil can cause it, so to can a
condenser fan that is not performing to design requirements, if enough heat
is not being rejected at the condenser because of dirt or a bad or faulty
fan it will be indicated in the compressor current draw. Oversizing wires,
if that is in fact what the latter contractor did, is not only bad practice
and stupid it is also dangerous. The wiring within the equipment is the size
(AWG), that it is for a reason. And finally, even though it would be
premature, provided the equipment is properly maintained, the fault may in
fact be a defective compressor, it certainly would not be unheard of. I
would contact a competent service company that uses meters to determine
cause.

Now secondly here. If the end only that tie on to the compressor are
melting about 1 to 3 inches back up the wire from the compressor. You have

You have not given the model number or serial number to the unit. Depending
on the model and serial, you may have a couple of items, and if you will get
that and either post it, or send it this way, we can pull up the unit, and

See the reply above. Once I know what model and run line of unit you have,
then its a simple matter of pulling it up on cd and badda bing...there you

The reason I need that, is that some of those had issues, that looked one

There is no such thing as a shorted out compressor, somewhat. It's either
shorted out or it is not.


This is Turtle.

Hummmmmm , You must not have checked too many compressor lately have you.
The test to check for a shorted or internal short from one pole to the other
is to use a OHM meter and see if you have a path to gound first and then
read each of the terminal to the other to see if you have the correct ohm's
throught each. You read from R to S and get the ohm reading and then read
from R to C and S to C and add the two together and you should get the ohm
reading you got by reading R to S. If they don't match you have one winding
touching the other some where in side the motor it'self. They can still run
with a bleed over. Now for a simple explained condition of this is when you
hear a tech say That compressor is just high amping too much or just pulling
too many amps. This is what he is telling you here. A short out compressor
does not have to be to ground and can be a short from one winding to the
other and when I say somewhat. This is what I'm speaking of.
There is a reply below here too.


Keith the correct answer to your question, or at least as correct as any
observation can be using the information available and considering this is
as I always say the internet. Each of the three wires on your compressor
represents it's own respective winding in the compressor. Each, when
excessive current draw is present, indicate to a competent (dare I say

that
word here), technician the correct path to follow with respect to
troubleshooting. So in order to even begin to remotely guess at the

problem
one would need the information specific to which wire is carring excessive
current. Even though they all may indicate excessive current, simply due

to
the proximity of one to the other, there is one that is the actual carring
the excessive current. With that being said, the first thing a service

There
are a multitude of factors that can contribute to issues with the run
winding in the compressor. To begin with the run cap itself can be
defective, has anyone tested or replaced it?


You are saying here that the problem may lie with the run winding because
the run capasitor or maybe the start capasitor maybe defective. I maybe
catching or reading you wrong here by you saying the run capasitor or the
start capasitor is in the run winding circuit in some way. I can't remember
here , is the run capasitor in the run winding ? Clear this up for me.



A dirty condenser coil will
increase the current draw on both the run and common windings in the
compressor,


Your saying the amps will go up on the Run winding and the Common winding. I
have never heard of a common winding on single phase compressors in my 40
something years in the business. They have a Common winding on 3 phase stuff
but not on single phase stuff. Clear this up for me.



has the coil been cleaned thorughly since the issues originally
occured. For the same reason that a dirty coil can cause it, so to can a
condenser fan that is not performing to design requirements, if enough

heat
is not being rejected at the condenser because of dirt or a bad or faulty
fan it will be indicated in the compressor current draw.


If the condenser fan motor is too slow / wrong blade / wrong R.P.M. / or
just not moving enough air throught the condenser and causing the compressor
to over amp. You will see a 90 to 100 psi suction and a 400 to 500 psi head
pressure on the freon system. Then you say the amp will go up to enough to
burn the wires off the compressor. If the amperage goes above the rated
limit of the compressor more than 5 minutes. The compressor will cut out on
high temp or high amps. If the amperage goes up enough to melt the wires to
the compressor the service breaker or the internal overload will trip and
cut it off. I just can't see the amperage staying above 60 to 90 amps for
very long at all with out something cutting it off. One other thing here. If
the amperage goes above the rating limit of the compressor more than 5
minutes it will turn off for 2 to 4 hour while it cools off. Clear this up
for me.




Oversizing wires,
if that is in fact what the latter contractor did, is not only bad

practice
and stupid it is also dangerous. The wiring within the equipment is the

size
(AWG), that it is for a reason.


You say by using a larger compressor wire kit is Stupid and is also
Dangerous. You also said the wire to the compressor is designed to be a
exact size [AWG] and you should not go up on it. I just don't see any danger
in upping the wire size kit to the compressor unless your using the wires as
a fuse and will burn off at a high amp rate. I alway just put a breaker on
the whole condenser and use it and not the compressor wires as a fuse link.
Clear this up for me.


And finally, even though it would be
premature, provided the equipment is properly maintained, the fault may in
fact be a defective compressor, it certainly would not be unheard of. I
would contact a competent service company that uses meters to determine
cause.


Now this I agree with finally.

wires to capacitor on YORK AC unit are burned and melted
 
I have not taken any measurements on the unit, neither did any of the
technicians who worked on it. One tech said that he would be glad to keep
charging me $100 for each visit to replace the wires. Otherwise, I should
buy a new unit. I will do that if I have to but not sure I need a new unit
to fix the problem.

I bought the house 4 years ago and the unit was about 5 years old when I
bought the house. I don't know that is has ever been flushed. Neither tech
suggested that to me.

friend said that it might have a starter relay on top of the

compression
that is not shutting off after the compresser is started. I have

not
taken
it apart to look.

Does this sound correct? I don't understand why the repair guys
wouldn't
know this? Any other suggestions on the cause of the problem?

Thanks,

This is Turtle.

First here, If the wires [ like the whole length is melting ] is

melted.
You
have these things wrong with it. You have too big of a breaker to your
condenser unit or have to reset the breaker every hour or so, The wire

kit
he put on it is too small, and You have a shorted out compressor

somewhat.
If everything is installed correctly. You can't melt the wires.

There is no such thing as a shorted out compressor, somewhat. It's

either
shorted out or it is not.


This is Turtle.

Hummmmmm , You must not have checked too many compressor lately have you.
The test to check for a shorted or internal short from one pole to the

other
is to use a OHM meter and see if you have a path to gound first and then
read each of the terminal to the other to see if you have the correct

ohm's
throught each. You read from R to S and get the ohm reading and then read
from R to C and S to C and add the two together and you should get the ohm
reading you got by reading R to S. If they don't match you have one

winding
touching the other some where in side the motor it'self. They can still

run
with a bleed over. Now for a simple explained condition of this is when

you
hear a tech say That compressor is just high amping too much or just

pulling
too many amps. This is what he is telling you here. A short out compressor
does not have to be to ground and can be a short from one winding to the
other and when I say somewhat. This is what I'm speaking of.
There is a reply below here too.


Keith the correct answer to your question, or at least as correct as any
observation can be using the information available and considering this

is
as I always say the internet. Each of the three wires on your compressor
represents it's own respective winding in the compressor. Each, when
excessive current draw is present, indicate to a competent (dare I say

that
word here), technician the correct path to follow with respect to
troubleshooting. So in order to even begin to remotely guess at the

problem
one would need the information specific to which wire is carring

excessive
current. Even though they all may indicate excessive current, simply due

to
the proximity of one to the other, there is one that is the actual

carring
the excessive current. With that being said, the first thing a service

tech
would do is use an Amprobe to determine the actual draw in each

conductor,
I
further suspect that your friends assesment is incorrect, if what he
indicated to you were true, you would get zero run time out of the
compressor, it would quickly overheat and cut out on an embedded thermal
overload-quickly, not a few days, few weeks or few months. There would

also
be other indicative attributes that you have not mentioned.Since from

what
I
read the most educated observation that can be concluded is that the

problem
is associated with the run winding, assuming the capacitor that your are
referring to is in fact the run capacitor and not the start capacitor.

There
are a multitude of factors that can contribute to issues with the run
winding in the compressor. To begin with the run cap itself can be
defective, has anyone tested or replaced it?


You are saying here that the problem may lie with the run winding because
the run capasitor or maybe the start capasitor maybe defective. I maybe
catching or reading you wrong here by you saying the run capasitor or the
start capasitor is in the run winding circuit in some way. I can't

remember
here , is the run capasitor in the run winding ? Clear this up for me.



A dirty condenser coil will
increase the current draw on both the run and common windings in the
compressor,


Your saying the amps will go up on the Run winding and the Common winding.

I
have never heard of a common winding on single phase compressors in my 40
something years in the business. They have a Common winding on 3 phase

stuff
but not on single phase stuff. Clear this up for me.



has the coil been cleaned thorughly since the issues originally
occured. For the same reason that a dirty coil can cause it, so to can a
condenser fan that is not performing to design requirements, if enough

heat
is not being rejected at the condenser because of dirt or a bad or

faulty
fan it will be indicated in the compressor current draw.


If the condenser fan motor is too slow / wrong blade / wrong R.P.M. / or
just not moving enough air throught the condenser and causing the

compressor
to over amp. You will see a 90 to 100 psi suction and a 400 to 500 psi

head
pressure on the freon system. Then you say the amp will go up to enough to
burn the wires off the compressor. If the amperage goes above the rated
limit of the compressor more than 5 minutes. The compressor will cut out

on
high temp or high amps. If the amperage goes up enough to melt the wires

to
the compressor the service breaker or the internal overload will trip and
cut it off. I just can't see the amperage staying above 60 to 90 amps for
very long at all with out something cutting it off. One other thing here.

If
the amperage goes above the rating limit of the compressor more than 5
minutes it will turn off for 2 to 4 hour while it cools off. Clear this up
for me.




Oversizing wires,
if that is in fact what the latter contractor did, is not only bad

practice
and stupid it is also dangerous. The wiring within the equipment is the

size
(AWG), that it is for a reason.


You say by using a larger compressor wire kit is Stupid and is also
Dangerous. You also said the wire to the compressor is designed to be a
exact size [AWG] and you should not go up on it. I just don't see any

danger
in upping the wire size kit to the compressor unless your using the wires

as
a fuse and will burn off at a high amp rate. I alway just put a breaker on
the whole condenser and use it and not the compressor wires as a fuse

link.
Clear this up for me.


And finally, even though it would be
premature, provided the equipment is properly maintained, the fault may

in
fact be a defective compressor, it certainly would not be unheard of. I
would contact a competent service company that uses meters to determine
cause.


Now this I agree with finally.

You can stop right here for i'm looking at the effect of a loose connection
wire burn out. I see them all the time when the connection of the wire is
not tight and it will just burn off. Replace the contractors and run new
wire to the compressor to the contactor and you will never hear from it
again , but tighten the connection real good and don't use the male spades
if all possible , also.

I bought the house 4 years ago and the unit was about 5 years old when I

This is Turtle.

If the Tech / service company can't tighten up the connection enough to keep
them from burning off. Two thing is taking place here. 1) He is wanting to
sell you a new condener by leaving the connection loose and let them burn
off. 2) The tech just does not know how to tighten up the connection
correctly.

Run their ass off before the mess something up here and you may really have
to buy a condenser.

when a terminal is corroded?

4) What is the electrical current path through a compressor? For example,
which terminal is hot, and which is neutral?

I will likely be working on condensing units this summer, and perhaps some

I fully agree with Turtle that the contactor (relay) is bad.

I'm not a HVAC technician, but I am an electrical engineer with 15 years of
experience testing contactors and relays. The photos show that the terminals
are corrode; chances are, the contacts of the contactor are as well. Fungus,
corrosion, and normal usage can cause an increase of resistance on
electrical contacts. An increase of resistance will cause a voltage drop to
appear across the contacts of the contactor thus making the contacts
dissipate more power (heat). From what I see, the wires are burned near the
relay. I have seen this condition many times in relays that were under
test. The contacts get hot enough to melt the insulation on the wires near
the relay but not hot enough to melt the relay. Replace the relay and the
wires and that should solve your problem.

Turtle is a smart cookie.



Keith Reding February 11th 04 10:39 PM

Sounds reasonable. The first time the wires burned through it was at the
capacitor. The second time it was at the relay. The third and current time
is at the relay but the wires going to the capacitor looks fine. I will
replace the relay and wires and hopefully that will make a difference. Each
time I have had burned or melted wires they have been at the connectors so
hopefully this will fix the problem.

Thanks to everyone for their assistance.

According to Tony Berlin :
There is no such thing as a shorted out compressor, somewhat. It's either
shorted out or it is not.


Not true. A single adjacent shorted out winding will cause the current
draw to go way up, but the motor will usually still turn fine (more or less).

I think Turtle may be drawing attention away from the right thing to check,
but he's quite right insofar as motors can easily draw more than they should.
Ie: shorted windings, stiff bearings or seals, etc.

The fact that the condenser wiring is melting is very suggestive (especially
after wiring and condensor replacement), not of a winding or condensor
problem (a shorted condensor could do this), but that of the start switch.

_Normally_, the condenser is only connected to the start winding for
a few seconds at most while the motor is getting up to speed. Once the motor
nears operating speed, the condensor and start winding are switched off.
The condensor wiring shouldn't be in-circuit long enough to get hot even
if it is drawing too much current.

Having the condensor wiring overheat is suggestive of one of two things:

1) the start switch is malfunctioning and holding the start winding
in-circuit too long, and (possibly in addition), there's a short in
the start winding and it's pulling too much current when it is
in-circuit.

2) The motor is taking WAY too much time to get up to speed (bad
bearings, semi-seized seals etc), and hence the condensor circuit
is remaining in-circuit MUCH too long.

There are other possibilities (ie: the condensor capacitive value is
_grossly_ wrong, but unless you have gremlins running around replacing
start condensers without you knowing it ;-), unlikely)

Motor windings rarely fail and are quite expensive to "repair", so I'd
concentrate elsewhere first.

I'd look into the start switch and making sure it's not fused (spot
welded) closed. Often just "unsticking it" and polishing it up with
a nail file or similar does the trick.

Also check to see whether there's too much rotation resistance. Maybe
it needs new seals. Or a new compressor. Ugh.

Don't be surprised to find that contactor full of ants.
For some reason they are attracted to those things like bees to pollen.
Nothing like a dozen flattened insects to raise resisance.

According to TURTLE :

I bought the house 4 years ago and the unit was about 5 years old when I
bought the house. I don't know that is has ever been flushed. Neither

tech
suggested that to me.


This is Turtle.

If the Tech / service company can't tighten up the connection enough to keep
them from burning off. Two thing is taking place here. 1) He is wanting to
sell you a new condener by leaving the connection loose and let them burn
off. 2) The tech just does not know how to tighten up the connection
correctly.


Turtle, I see _significant_ corrosion on the terminal screw (on at least)
the lower of the two hot spots. See first picture - has the best view.

Not only is the screw and metal conductor corroded to crap, the black plastic
(or bakelite) on the terminal is clearly baked and is going to start
disintegrating.

You can winch new wire down as much as you want, but with that much corrosion
on the terminal, it's never going to stay "fixed".

The pictures aren't good enough to tell if the upper terminal connection
is as badly damaged.

That thing appears to be a relay. I think it needs to be replaced or
refurbished somehow. If it's the start relay (see my other posting),
the contacts may also be sticking (or permanently stuck) and be the
original cause of the whole mess.

I can't believe a serviceman would simply replace that wiring harness without
at least commenting about the condition of the relay. Sheesh!

Thats a Model number: H2DA042S06 style A.
No Q in it.

As information, last date on record for that unit was 11-30-93. It was never
registered under warranty. Gotta love it.
As far as the pics go, you have a very simple problem to fix. As long as the
compressor is not overamping once the job is complete, you are ok. The
contactor is bad, and the terminals are loose....even when they have
replaced the wire.
All the 220VAC leads need to be as tight as possible, otherwise they will
overheat and you get that problem.

Chances are, that the leads to the compressor at the R and S terminals are
loose as well, and will further add to the overheating.
The correct run capacitor for that unit is a 45-5-440, and you better have
that on there as well. if they have not replaced the cap, do so.
The correct contactor for that unit is a single pole, 30 amp, 24v coil, with
shunt. common unit, and the correct part number is 02425835700, Source One.
It is in phase out mode, and the price will be about $26 for the correct
one. The capacitor is a little higher, for the correct York part...they run
according to the listings for about $29.00.
sure, you can get them for less, but as a York dealer, I only use Source One
parts, as I dont have to make any modifications to anything.



Here are the links to some photos showing the burned wires. I thought the
burned wires were connected to the capacitor but they are not. See the
photos for a better explanation.

Chris..if you had a clue, and you dont, (lets be honest here, and stop
trying to fool folks about your background and knowledge) then you would
know what a condenser flush is. Some also call it a foam out. Others call it
a cleaning.
Either way, the idea is to loosen the accumulated dust, grime and oils from
deep in the fins, flush them out, and restore proper coil to air contact.
IF the coil is clogged, as many are, then the fan amps go down, the fan
speeds up, the heat pressures go up, the compressor amps go up, and if the
compressor does not shut down on thermal, it will overamp and possibly
create in some isolated circumstances the same problem that the OP has.

Couple things. First, Turtle is a smart cookie, and from what I can read of
his posts, an excellent repairman.

I did look at a couple of the pictures. Since the wire from the cap goes to
a terminal block (and two other things) it makes me wonder if this is a load
carrying wire, not just from the comp to the cap. The wire you pointed to
with the arrow does appear smaller than the other wires.

Wonder if a dab of Noalox would be a good idea for these press on terminals?
Cut down on corrosion.

Keith, after viewing your pictures and reading the various posts, as a tech I'd
take the following steps to remedy your situation:
1) replace the one pole contactor with another 1 pole contactor, 40 amp rating
2) cut the wiring back to clean, unburnt copper and crimp on eyelet connectors
that attach to the contactor with screw lugs
3) replace the capacitors with either single capacitors rated for their
respective loads (condenser fan motor and compressor) or as CB mentions, the
correct dual cap that originally came with that unit.
4) ensure that the wiring lugs at the compressor terminals are electrically
tight, not corroded, and NOT of the male spade variety, as Turtle mentioned.
Install split bolts if you have to.
5) like the moron tony berlin suggested, flush your condenser. what he really
meant was wash the condenser coils to ensure cleanliness, free from dirt and
debris.
6) ensure every high voltage electrical connection was tight, starting from the
circuit breaker panel, to the disconnect, to the connections inside the
condenser.
7) finally, depending on a lot of factors, i may install a hard start kit. you
see mr berlin, i'd be looking at my startup and RLA AFTER i'd completed ALL of
the above steps.

On a side note CB, your star will shine alot brighter when you cease with your

its just unfortunate he had to ask them of that brain dead egotistical tony

you
see mr berlin, i'd be looking at my startup and RLA AFTER i'd completed

ALL of
the above steps.

On a side note CB, your star will shine alot brighter when you cease

with

questions,
its just unfortunate he had to ask them of that brain dead egotistical

I thought I would get my York central AC unit repaired well before

cooling
but the fan still ran fine. The repair guy look at it and the

wires
going
from the compressor area to the capicator had melted and stopped
working.
The repair guy replaced the wires and the capicator. A few months

later
it
happened again. A different repair from another company installed

a
heavy
duty wiring kit and the unit worked again for a few months then

stopped
when
the wires melted again.



Obviously the unit is pushing too much current through these wires.

A
friend said that it might have a starter relay on top of the

compression
that is not shutting off after the compresser is started. I have

not
taken
it apart to look.

obviously...no.
You have not given the model number or serial number to the unit.
Depending
on the model and serial, you may have a couple of items, and if you

will
get
that and either post it, or send it this way, we can pull up the

unit,
and
tell you what is the most likely problem.

Does this sound correct?

Nope...not always.

I don't understand why the repair guys wouldn't
know this? Any other suggestions on the cause of the problem?

See the reply above. Once I know what model and run line of unit you

have,
then its a simple matter of pulling it up on cd and badda

bing...there
you
go.

The reason I need that, is that some of those had issues, that looked

one
way, and were another.

Thanks,

wires to capacitor on YORK AC unit are burned and melted

Snip

Keith, after viewing your pictures and reading the various posts, as a

tech I'd
take the following steps to remedy your situation:
1) replace the one pole contactor with another 1 pole contactor, 40 amp

rating
2) cut the wiring back to clean, unburnt copper and crimp on eyelet

connectors
that attach to the contactor with screw lugs
3) replace the capacitors with either single capacitors rated for their
respective loads (condenser fan motor and compressor) or as CB mentions,

the
correct dual cap that originally came with that unit.



Read his later post...thats part of his issue for almost sure.



4) ensure that the wiring lugs at the compressor terminals are

electrically
tight, not corroded, and NOT of the male spade variety, as Turtle

mentioned.
Install split bolts if you have to.
5) like the moron tony berlin suggested, flush your condenser. what he

really
meant was wash the condenser coils to ensure cleanliness, free from dirt

and
debris.
6) ensure every high voltage electrical connection was tight, starting

from the
circuit breaker panel, to the disconnect, to the connections inside the
condenser.
7) finally, depending on a lot of factors, i may install a hard start kit.

GF..you know me as well as any...and while I agree with you to a point and
respect your thoughts on the matter, the more I read of that morons
postings....well...you already know..
Personally, I take his giving advice as an attack on a trade, that by Keiths
uneducated tech proves, has enough idiots working in it that continue to
pass themselves off as fully trained, and licenced persons.
It bugs me in a way I cant describe.

Sounds like a plan. My neighbor used to do AC repairs so he can certainly
help me install the correct cap, especially if I have a wiring diagram.

The AC originally had a single capacitor but the first repair guy said

it
was crap and replaced it with the two separate units.


Nope..it wasnt crap..it was the RIGHT part, and it was a GE BTW, one of

the
better ones.
What hes done now, is part of your problem.

How does he have them wired? In series, or parallel?

Damn...to think there are techs out there that do that kind of work, and

get
away with it.

I normally dont do this, but if you want the right one, I will verify
pricing in the morning, and if you need one, get you a wiring diagram, and
tell you how to fix THAT problem. I am willing to bet that my York supply
has it for less than the dealers net lists it for....since we only use

that
for part numbers anyway.

The unit is a York Model H2DAQ42SQ6A. The Serial Number is

ELBM396211.

Here are the links to some photos showing the burned wires. I

thought
the
burned wires were connected to the capacitor but they are not. See

the
photos for a better explanation.

Actually, I know all the answers to the questions I asked -- I didn't think
Tony did. With Tony Berlin's bad attitude, I put him in the killfile right
next to CBH.

Stormin Mormon February 12th 04 02:55 PM

wires to capacitor on YORK AC unit are burned and melted
 
In order to assist Tony (whose messages no longer appear on my screen) I am
providing the answers to the test. Enjoy!

1) You say that each of the three compressor terminals represents its own
winding. I know of two windings, but you say there are three. What are the
names of the three windings, and what do they each do?
SM: There are two windings. They are the start winding, and the run winding.
I didn't think Tony could answer this one.

2) What are the names of the electrical terminals on a typical compressor?
What does each terminal do?
SM: Common, start, and run. Common acts as a neutral, though on 220 volt
comps, the common terminal is "hot". Start provides for extra torque for
starting. On refrigeration compressors, the start terminal is usually only
powered for a second or two, via a start relay. On AC units, it is often
hooked to a motor run capacitor. Run terminal provides the power to run the
compressor.


3) In terms of temperature, what happens when a terminal is corroded, and
trying to carry current? And in terms of the electrical flow, what happens
when a terminal is corroded?
SM: When a terminal is corroded, it provides a resistance. Also can be
called a "load". This blocks or reduces the flow of electricity, and turns
the electricity to heat energy.

4) What is the electrical current path through a compressor? For example,
which terminal is hot, and which is neutral?
SM: During startup (of start relay units) power is supplied to the S
terminal, and exits through the C terminal. After the compressor motor
starts, power is then supplied to R terminal,a nd exits through the C
terminal. In some AC compressors, the power is applied to R terminal, using
C for neutral. S and R terminals goes to a motor run capacitor.

Thats hilarious, since you reply to me everywhere else, including your
little Yhoo group...:)
And Chris, I dont have a bad attitude...I hate that you are giving answers
to things you have no clue about....and have given wrong, and at times,
dangerous advice.
You are an amatuer, playing pro...and that, is just wrong.
