Have the same fan motor issue. Can help it start but it

Customer Question

Have the same fan motor issue. Can help it start but it won't start on its own after being off for a while.
JA: I'll do all I can to help. How long have you been dealing with this?
Customer: A week. Hums then just sets. I can spin fan and it turns on fine. Also will start by itself if it has been running very recently. Only after setting for an hour or so, it won't start on its own.
JA: Do you plan on doing the work yourself?
Customer: Yes
JA: Anything else we should know to help you best?
Customer: Can remove motor, etc and replace if convinced that is the only issue.

Sounds like most likely a weak capacitor if this is a PSC motor.Do you have a capacitor with 2 brown wires from motor?

OK that cap is most likely the problem, Does it look puffy at all?http://i.imgur.com/12sSxri.jpg

It can still be bad or weak even if it looks new. Below shows how to test.If you do not have a meter to check capacitance you can take it off and take it to an appliance parts store and they will test it for you.Or you can replace it for about 10 bucks and that will probably solve your problem

Tested capacitor and no reaction so your replacement suggestion should be sufficient.
Thanks
