20 year old Carrier, the blower motor was just humming and would not turn. I replaced the capacitor and it ran fine for about 20 hrs. in the Fan On mode and AC running, then just stopped and motor is just humming again when powered up. Any ideas?

Sounds like your motor is bad . Possible bearings. No oilers on motor. You replaced capacitor. Motor is only thing could be now. 20 years is good service. Russ

That is what I had figured. I did have it serviced about 8 years ago and supposedly the motor and capacitor were replaced. If I replace the motor should I replace the capacitor again?
HVAC Technician: gotoman for ac, HVAC Technician replied 2 years ago

Depends on motor. The motor you buy may have a different size capacitor. If it is same size capacitor just use the one you bought. Russ
