[TiAgM3]

Hello first time posting. I have a Carrier A/C unit and yesterday the compressor fan motor did not come on when it was supposed to. I went and checked it and it sounded like it was jammed or something "motor trying to move but nothing would happen" I moved the fan with a stick and it the fan began working on its own. As the day went on I realized that the fan would continue to not start on its own but work if I got it going. I took the fan of and it looks like the bearings are fine. Would this be typical of a bad motor or something else. You help is greatly appreciated.

check the start capacitor

Ain't got a start capacitor.

Its a run capacitor.

Trivial, until you use a start cap and burn up the motor. Or worse.

How do you check the capacitor? From the reading I have been doing it is a dual purpose capacitor. The motor is a HC39GE237A with 3 wires (brown/yellow/black) coming into it.

mis worded.. My mistake.. Yes it's split part for comp & part for motor.. There are cap. testers . You can use v m. to know if it's gone.. Some will look bloated. Like they are about to expload

How do you check the capacitor?

You'll need a DVM, a 9v battery, some clip leads

and a one megohm resistor from Radio Shack.

Can you post a photo of the markings on the cap? Look for "uF".
