Subject: Corsair AC unit squeaks loudly

JS From: Jack Sandweiss

JS I'm very naive on this issue. I just bought a home with a Corsair AC
JS which intermittently squeaks loudly (never when the AC person is
JS here).

This could be one of several things. it could be a motor or it could be an
internal compressor relief etc...

JS It always cools. It tends to squeak more often when just
JS starting or stopping, but sometimes continually. Sometimes, when it
JS squeaks while stopping, there is a "whoosh" sound at the end.

This is ok if it is a heat pump. if it isn't a heat pump this is leaniung
towards a bad compressor.

whoosh is normal - not a problem
compressors don't "squeak"
but blower fans do, and so do condenser fans, when bearings are failing or
out of lubrication

This is Turtle.

Corsaire was the original old name for Rheem up till the early 1960. Then it was
change to Rheem Manufatoring co. . then in the late 1990's Rheem went back to
making the Corsaire brand as a 4 th brand to sell. Rheem , Ruud, WeatherKing,
and Corseaire .

If it is the old model Corseaire from the 50's you really need to replace it but
if not oil the motor for it has oil holes on the fan motor.

If it is the newer model made in the 1990's and 2000's it don't have oil holes
and you need to just change the motor out. Now the check to see because the New
Corseaire condensers have a 5 year warranty on all parts like the Rheem
equipment.

Also I'm not sure they make the Corseaire in the years 05 or 04 but will check
to see. I can be off on my years for time gets away from me.

So before closing out here. I would Oil the motor and check the bearing for
slack.

The unit is 4 years old. The blower fan is "self-lubricating" if this
helps. Where is the "condenser fan"? Would that be in the attic or the
unit outside?

the BIG fan, usually on the top of the unit

Thank you all for the replys. This house was built in 2001, and it has a
"self-lubricating" fan motor.

If I can be certain, that it's NOT the compressor, I could have the fan
motor replaced for around $300, and would do that. We are not the
original owners, so any guarantee would probably not apply. Is there
any way to rule out a compressor problem?

Jack

Jack,

The Whoosh is the reversing valve of the heat pump changing from
cooling position to heating position & is normal. The squeak is most
likely the outdoor (condensor) fan motor. It could be a cabinet
squeak, but not likely. I have never heard a hermetic (Tin Can)
compressor make that kind of noise (Squeak). Try oiling the outdoor
motor if it has ports. Use 20 or 30 grade non-detergent motor oil. If
you use detergent motor oil, eventually the oil evaporates, leaving the
detergent to lubricate the motor, which it won't. But of course that
will take several years.

The blower motor refers to the motor that moves air through the ducts.

Hope this helps

Yes, Stretch, this helps a lot. The outdoor motor does not have ports,
so I will probably have it replaced. You have helped greatly with
definitions.

if this is an A/C only this sound is not normal. what you are hearing is the

you should turn the unit off immediately before it is permanently damaged.

JS I'm trying to avoid buying an entire new unit, if, replacing the
JS condenser motor is all it needs. Thanks for your reply.

if you turn it off now and have it repaired it may be ok but it could have
been damaged already. sometimes these internal relief valves can open and
stay opened which means you will need a new compressor. of course running
this long with the valve opening has also put quite a strain on the system
but if you get it repaired it could last for several years or it could fail
in a week, a day, Etc...

With all due respect, my email is fine. I have been sending/receiving

Thanks so much for the quick reply. Well, I guess it's my gamble. The
total time it has operated with the intermittent whooshing has been
about 5 hours. One final question, if you don't mind: Can the relief
valve be separtely replaced, or is it part of the compressor? I'm trying
to determine if I should have the fan and relief valve replaced as an
alternative if that is a possibility. And, if you're saying that there
should be NO whoosh after turning it off, then that might indicate to
me, that the valve is already damaged, or is this poor logic.

The bummer is that this is a 4 year old house, and we're not the first

The valve is internal to the compressor and cannot be replaced separately.
The only way you will hear the noise is if the pressure is too high or if it

I talked to the HVAC shop owner this am, and he reviewed everything,
felt it was the condenser fan for certain, and that there was probably
no damage to the valve. He has the serial# of the unit, and will check
and see if anything is under warranty. He will be out tomorrow
afternoon, and I have confidence that he will be fair, and get it fixed.
I only hope it's noisy when he's here, but will replace the fan anyhow
at the least.

Thanks to everyone for your help. I'll let you know how it turns out.

We learned a lot. We replaced the condenser motor and the problem
continued. We called in more experienced (in our opinion) the
Contractors listed in the Homeowners Manual (Jet Residential LLC) about
60 miles away.

Finally, the unit squeaked, etc. when he had his gauges on, and he
immediately determined that is was the compressor. This man came with
HIGH recommendations from our neighbors. He said that the Rheem Corsair
was a very inexpensive unit, and we replaced it with a Carrier (which
has a scroll compressor). We are cool and happy.

Again, every time I come to this group, I end up learning a lot. I hope
I made the correct decision, but sometimes it comes down to experts and
subjective trust. I may have them come out yearly to give it once over
in the spring.

Thanks again,

Jack
