No AC or Heat, HELP

[Cathy&Paula]

My ac and heating unit quit working last night, I checked all the fuses I could find and the breaker but no luck. Is there somewhere else I should check underneath the coach for another fuse or breaker? The thermostat control will not light up so could it be the control? Any help would be great because it's suppose to get very cold.

Thanks

In my DSDP, the 12v fuse that powers the thermostat is in the bath next to the 120v panel.

I believe it's marked "air cond".

12v feeds the front air cond and the thermostat gets it's 12v from the front air cond.

Until you can locate the problem, go out and buy an electric space heater. It should take care of the cold. We have two and they keep the coach toasty.

Here is a PFD for thermostart
And here is one for AC & HEAT PUMP SYSTEM

The Duo-Therm will wire to control unit in first AC,someone had same problem with control unit and swapped the control unit out of rear AC with the front AC and got his heat.
Not saying its you problem but PDF's should help you resolve your problem.

It was my thermostat, I hooked up a phone to the jack coming into the thermostat and it showed in use so I put a new thermostat on and it works great now. Thanks for all the info
