The unit is a York Model H2DAQ42SQ6A. The Serial Number is ELBM396211.

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.

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.

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,

Keith
