Dometic thermostat control

[motts461]

Hey Guys, uncovered the 2014 27HFS yesterday so the wife could start putting all the stuff she bought over the winter in the camper, haha. I pulled the battery out over the winter to keep it charged and re-installed to give her light. I also plugged the power cord into a 110 outlet as to not run the battery down. When I did this the A/C turned on. I went inside and the Dometic control unit was blank, no visible read out on the display and no light indicating what mode it was in. I pressed some buttons and checked for a battery under the cover with no success. I ended up unplugging the cord until I have time to troubleshoot. We just bought the unit last fall and only used it twice so I do not have a lot of experience with it yet.

Can anyone give me some advice, Thanks in advance.

I don't have a digital thermostat but here is manual in case you need it.

I have the 2013 version but I think the thermostat is the same. I would start with the breaker / fuse panel under the fridge. When opening mine last weekend I found one breaker tripped Rather odd because nothing was plugged in over the winter. The only thing I did electrically was start the generator a few times but the reset of the breaker did the trick

The breaker was for the water heater Again no reason I can find for that happening and it's working fine

Checked fuses, breakers and tried to initialize from manual still the same. Made a call to dealer today and waiting on response.
