Follow-up on the motel-style AC/heater (in the building that was sold but now we're renting).
The main problem has changed and now it is that the aquirrel-cage fan motor doesn't start spinning. It won't start at all on slow, and on high only if I spin it a screw-driver first. It's not very practical to keep going over and spinning it with a screwdriver, especially when no one is there.
The open end of the squirrel cage faces into the building, and is behind a sheet of steel that shows no easy method of removal. I thought I could take off the cover on the outside of the building, but I see no screws, etc.
1) Do I have to remove the entire unit from the wall? It's about 3 feet wide by almost 2 feet high, by about a foot deep, and probably heavy. (I didn't see screws even on the inside to remove the whole thing. I should have written the brand and model, but didn't, and the building was locked today.)2) The fan cage spins pretty easily in both directions when the power is off, and sometimes the fan starts up when I spin it with a tool, but other times it seems to be held in place magnetically and it doesn't even want to spin when I try to spin it. Am I delusional?
Backrgound: It was making scraping noises from the fan, after running
10 hours or more. We turned it off and it was cool out anyhow. When I restarted it so I could fix it, the scraping had stopped except once for a couple seconds, but if it recurs, I'll worry about that then.
