Dometic thermostat control not operating

[Barbarian Coug]

Good morning from Mammoth Lakes, California. It's cold this morning and I can't get the furnance up and running. The panel is blue with energy - but no controls are operating. This is our first trip in our 2014 Montana. Before I left home I tried to turn on the fan when the trailer was hooked to a 15 amp shore power. I never got to the fan and the A/C burst on before I could shut it off. It tripped something - but all the circuit breakers are on and all the 15 amp fuses visually appear 'hot.' Dometic service is closed for the weekend. Any help would be appreciated.

Well never mind - I pulled one 15 amp fuse to inspect it - put it back in - and bam - it worked. Thanks for playing the 'Gremlins are my friends.' Sponsored by "I'm not a rookie - I just act like in the campground."

Been there. Done that. Have fun at Mammoth. I used to go to the hot springs all the time in the 80's when I lived in El Lay. Love that area. Oh, welcome to the forum.

Set the Thermostat on AUTO then try it
