Subject: Corsair AC unit squeaks loudly---new symptoms

JS From: Jack Sandweiss


JS It is now squealing almost constantly and intermittently "whooshing".
JS The whooshing is no longer present only when I turn it off.
JS Question---If the squealing is associated with reduced rpm's of the
JS condenser fan, could that reduction bring about the whooshing?
JS It still appears to cool just fine, but is very noisy, and would
JS wake up the neighborhood if I had it on at night. I'll probably
JS just have the fan replaced and see if that fixes it, but am I
JS risking further damage if I continue to run it this way until I can
JS have the job done?

Is this a heat pump?

No, it is a separate AC outside. I have an Apollo (water) heating
system, but, AFAIK, that is totally independent of the AC. I've been
told by many that the whoosh is normal on shutdown of the AC. But, now
it is occuring intermittently during operation, with or without an
accompanying squealing, which sounds to me like a motor that needs oil.
I know about motors, but not AC units. The squealing has a "revolving"
rhythm to it. The fan is "self-lubricating".

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