RV Air Conditioner Questions

Got to the deer lease and the camper A/C wouldn’t fire up. I can hear the motor trying to spin, so it’s getting power. I reached up and spun the impeller with my hand and it felt like bearings were bad (almost felt like there was grit or something). I assume that’s a bad motor? Can I just change out the motor itself if that’s the case, or do I need to replace the whole unit? I’m hoping to not have to drag this thing into town and wait an eternity for a dealership to wrench on it if at all possible.

Usually it’s one motor that turns a shaft with a squirrel cage (blower) fan on one end, and a propeller style (condenser) fan on the other. Sometimes the bearing on the motor gets dry or gummed up and just needs some erl. I think you can replace that fan motor though, if it’s out.

if you have to replace the whole unit, you can do it yourself in 45 minutes.

You should be able to buy just the fan motor.

Thank yall! I’ll get a new motor ordered. I’ll give it a shot of oil this evening to see if that frees it up. I’d rather a new motor be on its way in case that’s only a temporary fix.

Thank goodness I had two emergency window units in there for backup!

Go on top and pull top cover/ foam inserts, have done alot that the foam failed/ binded or critters have built inside and will have somewhat same symptoms. Make a note of the fan end jam screw or clamp style. Some of the ones ordered will have a different end if whoever is ordering doesn't see that they are available with different ones

Justin, if you have to replace it I have a brand new, in-the-box Coleman Mach 15K BTU for sale. Holler if the motor replacement doesn't do it. I would find a reliable mobile tech if it is something you don't want to tackle yourself.

I had wasps make a nest in the AC that kept the fan motor from turning. Broke it loose and cleaned out the nest and it worked fine. Next problem I had with a travel trailer AC was a bad capacitor. A simple fix to replace a bad capacitor.

Similar problem with mud daubers. They can cause a lot of problems.

I had my motor freeze up a few months back when we were getting 100 degree days. I kept spraying oil on the bearings and spinning the squirrel cage and it started working right again, but had to do this many times over the summer. But I did order a new motor and replaced it a few weeks ago. The old bearings were extremely rusty. I did replace the capacitors while the cover was off.
