A/C Condeser fan motor problem. Anyone know where I can find a bearing set for one, or a possible replacement

Question

I have a 1/6 hp, 1ph, 208-230 v, 1110 rpm fan motor making a noise like a bearing going out. I oiled it and it stopped making the squeeling for a few days, but started again. It is on a Transtar outside A/C unit for Residential and is 15 years old. It mounts with 4 studs on the back of the motor with the fan shaft down spinning Counter Clockwise (??) if looking at the shaft first. Has anyone been able to just replace the bearing? I called about a new motor locally here and after 100 questions and 30 minutes later they said I would have to bring it by for them to try to match it.

Answer 1

Forget about fixing motor. Replace it. Just take it down there and they will match it up. You might find a used one somewhere but a new one will last a long long time.

Answer 2

check oem specs and see if a rain slinger is needed to protect the motor.  You will have to replace the motor.  By the time you find the bearings and press them into place and rewire the stator and reassemble the motor. the 25-30$ is the best way to go.  buy the motor from a supply house rather than from the dealer you will save money.  good luck

Answer 3

They are probably bushings not bearings in that particular HP motor.United Refrigeration,Grainger,Johnstone Supply,or Insco will be able to cross reference that motor in 2 minutes.Check your phonebook under a/c suppliers.You'll only be out around 50$.

Good luck and get a new capacitor with it.

Answer 4

suspect you will have to replace the motor...if the bearings are gone, the motor is old and weaker than it should be...motors do age, and it will not be just that side's bearings, the other side will be going bad also...new motor time!

Answer 5

Check your local Grainger Store or check their website.

RE Michel on the East Coast stocks alot of A/c repair parts.

Now the guys at the place you called are very right reason withstanding alot of OEM parts are no longer built to original

part numbers  so the unit and serial #'s and part numbers

are often cross referenced.

Answer 6

call an aircond. supply house like grainger or johnstone. give them voltage, rpm's, shaft diameter and horsepower. that info should be stamped on the old moter. the match may not be exact but nowadays several are universal. the way you wire the motor dictates direction, speed ect. careful not to bend the blade when switching out. check with your local motor there about changing bearings. they are libal to tell you it's just as cheap to buy a new one.
