This morning I looked out my window and noticed the condenser fan was not spinning on my heat pump. I know it normally doesnt spin when the unit is in defrost mode and didn't think it was unusual.. at first.. Then, about 15min later I looked at it again and it still wasnt spinning. The system was on, in heat mode, and the aux heat was not on.
I went down to the air handler and felt the freon pipes. The suction was very hot, and the liquid was very cold. Usually the liquid is around room temp. Didnt have time to break out my temperature probe. Might do that tonight.
Anyways, turned the system off for 20 minutes, started it back up and the fan looked like it tried to start turning, but didn't. Left it on for 5-10 minutes and more frost started to accumulate on the outside coil (outdoor temp ~30deg), so it wasn't in defrost mode. I was able to spin the fan with a stick and it moved freely, so it seems the bearings aren't siezed. It seems like it just quit, or the controller logic is really messed up and thinks it is defrost mode when it really isn't.
I have the installer coming out to look at it tomorrow, but my question is, is there anything else to look at that could have been damaged by operating the unit like this? The last time I actually remember looking at the outdoor unit was a few days ago.
Unit is a Fridgidaire FT3BD with indoor air handler B5BM. Both units are 2.5 ton.
