This is a very old unit, but I'm trying to help out a friend. The compressor turns on but the fan won't start without a bump. The fan will run in the direction that it is bumped, which makes no sense to me. When there is no power applied the fan spins freely in both directions.
I replaced the run capacitor but the problem didn't change at all. The cap I removed was a 6µF, and nobody that I talked to ever seemed to have seen or heard of a 6µF cap. My replacement choices were a 5, 7.5, or 10µF. I chose the 7.5.
I have the skills and tools to fix this, I just lack the knowledge. I don't want to throw my friends money at the wrong items as they can't really afford this. I really thought that the run cap would have fixed this, but it didn't. I really don't want to purchase a new motor, which will be significantly more expensive than the run cap was, if it doesn't resolve the problem.
When you bump the fan and it starts spinning, the unit cools very well.
Any help with this would be greatly appreciated.
- I'm really curious why or how the fan will run in either direction.
