The air conditioning in one zone of my house isn't turning. I have a Goodman air conditioning unit in that zone. I noticed that the fan motor was very hot (estimate 150 degrees F). It was much hotter than the other unit that was working. I disassembled it enough to be able to turn the fan with my hand and the bearings feel good. I tried flicking the fan with a screwdriver with it assembled, but it didn't start up. It seems like the start capacitor is a common problem, but I wouldn't expect the motor would be so hot if that were bad.
I turned off the power and let the fan cool off, but it didn't help. I didn't hear any humming or anything. Any idea what could be wrong?
