It looks like the fan in the outside portion of my AC unit has given up - it
started making a squealing noise last night, and finally just stopped
spinning this AM. If I shut off the outside unit for a while, and let it
cool down real good, when I turn the power back on the fan will spin
briefly, then start with the noise again, and finally just freeze up -
sounds like a bearing has worn out or something. The information plate on
the outside unit says that it's is a UAKA 037JAZ, and the fan motor is F.L.A
1.3 HP 1/5.
It looks like replacing the fan motor should be no big deal - open the unit,
disconnect the old fan, connect the new fan, and everything gets cool again.
Am I missing anything?
This is Turtle.
That might be good advice except it's a Rheem and it requires a short end bell
to end bell length of about 4 inches. If you use the universial on it you will
get the 6" End bell to end bell and hold the fan blade to high to make the air
flow right. You better use the OEM to get it right.
I'll second that. A TripSaver motor will work, but most of the time you have
to drill holes through the lid and mount it that way. If you don't get it
centered properly you end up will a good wobble while it's running (which
will eventually cause the "mounting bolts" to snap off). Then, like most
Rheems/Ruuds, you will have a helluva time getting the blade off the shaft.
Then once you do get all of the rust off and get it mounted on the new
motor, it wobbles and is real noisy because one or more of the counterweight
"clips" has rusted and fallen off making it out of balance (which is
probably what killed the original motor by "eating" the bearings up). You
got to make sure the new blade has the same pitch or that can throw
everything off. Then you are going to have to install a seperate capacitor
because the new motor requirement will not match the MFs of the original
dual capacitor on the unit (plus it is good practice to replace the
capacitor when installing a new motor). Plus, is that one of the 850RPM
motors or the 1075?
Not trying to sound negative. Just giving some things you need to take into
consideration. It is NOT a simple swap out of a motor.....
Thanks to all for the information.
I had an HVAC guy from a Electrical / Plumbing / Mechanical company I've
used previously come out to do the job this AM - he replaced the fan motor
and the contactor - the fan motor and capacitor part is listed as $460, the
contactor part is listed as $97.50, and they charged me $65 for diagnostics
(the service call) - total cost to me was $622.50.
