re: HVAC help needed

Appreciate the help. Extra help with diagnosing the following would also be appreciated.
I replaced the capcitors because I came home last week and found the unit on, but the fan wasn't running and it was buzzing loudly and the condenser unit was hot. After turning the fan manually while the unit was off, it would turn on fine. So I researched and figured it was bad capacitors. Well I replaced both with exact VAC and mfd replacements, and it worked fine this last week. Woke up last night and same problem.
After tinkering with it this morning, I manually turned the fan while the unit was on to see if I could get the fan going, and it would turn for about 10 seconds after I gave it a push, then it would stop.
My next guess is that I might need to replace the fan motor.
Thoughts?

Yes sounds like your bearings on the fan are going out. Also, hard start kits are for the compressor not the fan.

I'm not an HVAC guy by any means, but my fan motor went out last year. Sounds like what is happening to you. It could also be the bearings on the fan motor.
