Rooftop AC fan barely moving
Edit: the fan also makes a noticeable and constant humming sound when it's running
Our last renters ended up having a problem with the rooftop fan
"we seem to have lost all power in the ac over night. It turns on, and I'm pretty sure the condenser is kicking in, it seems to be cold, but there is no powered behind the fan...
Any thoughts?"
(An hour later, before I responded he added...)
"I think we're good. Turned unit off for a while, and a lot of water drained off the roof. I think it was at least partially froze up. Lots of air flow now."
I thought the problem was fixed but then this weekend when we took it out for the first time since then and I turned on the fan and it was barely moving it all. The weird thing is that when I turn the fan on high it moves faster but is still incredibly slow (slow enough that neither speed causes any noticeable air flow whatsoever).
I'm up on the roof right now and both the fan that draws air from the AC block and the fan that blows air into RV cabin run at that same slow speed.
I've tried manually moving the fan blades and they seem to move fine. I even tried spinning them a little and then switching the unit on (but I haven't tried turning the unit on and then "jumpstarting" the fan because I'm a little scare of damaging something).
The renters said that whatever happened it ended up tripping one of the circuit breakers. I checked all the circuit breakers and the fuses next to them and everything looked fine. They also said that the problem occurred after running the AC for like 16 hours straight at a high level.
I opened up the service area from the roof and snapped a couple of pics in case that helps. https://imgur.com/a/krcnY
