I have a a 2000 silverado with the Roper LQ , very small lq , the AC unit is a coleman mach II and it worked just fine last time I plugged the trailer in and turned it on. Getting ready for a trip so was checking everything... and this time ABSOLUTELY nothing happens when I turn it on, trailer is plugged in, checked fuse panel and circuit breakers, all are good and flipped to on, none of the breakers say AC unit, just main and furnace etc. flipped them all anyway, still nothing. is there another box somewhere? a fuse inline somewhere that I dont know about? trailer is not level if that matters, its parking spot is slanted if that makes a difference. any help?? suggestions? RV place close to me does not touch AC units...

Can you determine if the switch/thermostat is working properly? Please see this pdf file for other information.>>>>>>>>>http://www.rvcomfort.com/pdf_documents/1976141_copy.pdf

Thanks Bookmarked that for the other half to look at. am just making sure there is only one fuse box in this trailer and I am not over looking something simple. I have to assume the AC is wired to the Main breaker as it does not have its own.

If it isn't doing anything, and does have power. Take the top cover off, and spin the fan blade by hand. It is common for the motor to seize if it sits. Once it starts to spin, oil the bearing and it will run a while longer. 10 minutes, or 10 years....

Most AC units will have a dedicated A/C circuit with its own breaker. Usually they are 15 - 20 Amps in the smaller and mid sized ratings. I would check the breakers with a VOM to make sure they are in fact working. Just flipping them on and off won't guaranty that they are reset.
If the fan's motor is frozen, usually you will hear a humming or metallic buzzing sound for a short time until the breaker pops. When the opperating switch is selected, you should hear some mechanical sounds. If nothing is occurring, I would suspect a lack of power to the unit.

exactly, nothing happens, as if there is no power, all of the fuses are good, none of the breaker switches were flipped to off. bugger... taking off friday and although I wont need the AC its still something I would like fixed. strange how it worked and then didnt just like that.

If the fan nor compressor are running than it is one three things. Either no power to the unit, a bad selector switch/thermostat, or bad dual run capacitor.
