So I've had the camper since 2005 (bought new). Never really used the A/C. Problem is, now that i want sell the camper, the A/c doesnt work at all. Camper is plugged into house power. Nothing, no fan, nothing. Checked the fuses on the fuse panel, everything looks normal. Not sure if battery needs to be connected in order to get anything. Haven't tried that yet.
Any ideas? I am sure they will charge me a fortune at the Rv center to diagnose.
Yep, the AC unit should be on it's own 20a circuit breaker in the power box. Cycle it a couple of times. This probably has a twist knob on the unit itself rather than a thermostat so exercise those as well. Should be able to remove the ceiling panel and check the wiring. Wiring diagram will be on line on the manufacturer's (not the trailer maker) web site.
I had to have the AC fan replaced on my '05 21SSO (warranty.) IIRR a few people had their fans replaced, it may have been a bad batch of fans / bearings.
You can try getting on the roof, removing the A/C cover, and see if the fan turns over by hand (power off!)

I agree, Sounds like a power problem, slowly cycle the fan switches & t-stat, listen for any humming noise or dimming of any lights in the trailer...if nothing, theres a good chance its either a breaker or broken wire/switch in the A/C unit.

Be sure to check the 12VDC requirement. I noticed you had battery questions early on in your post list. The 12VDC requirement for the T-stat should work from the 12VDC coming from your converter/charger unit and/or the battery.
Make sure you are in A/C mode and not heat mode.
When checking the A/C circuit breaker might be a good idea to turn it off and hold all the way down for reset then turn it back on. Sometimes they will be tripped and doesnt look like it is...
ALso if you are using a 15A/20A garage 120VAC circuit to run your trailer be sure the 120VAC is in the proper "green scale" range for running the A/C.
Just thinking out loud here....
