Does anyone have a good link for wiring schematics for thermostat heating and air or the electric diagrams for this RV. Fighting a power loss with my thermostat. Any help would be great thanks guys. Every link I try is no good.

There is 12 vdc fuse on the furnace control board, accesed from outside. That was my issue when thermostat went dark.

Do you mean the push button fuse outside near the on off switch or somewhere else. I don't know what vdc means.

Volts DC 12 volts and it is an auto style, older glass tube like with metal ends.

It sounds like what Tahiti16 is saying is that you have to go outside and open up the cover for the furnace. It's on the passenger side of the coach under the fridge access door. He's saying that the fuse is on the furnace control board behind that panel. My Dolphin and all the documentation are at the storage yard ten miles from here, so I am unable to confirm any of this, but that's what his instructions meant to me.

You are correct, fuse is on the control board.

We found that the power to the thermostat comes from the furnace. Our problem was an intermittent connection at one of those blue Scotch clips in the wiring at the furnace. I wiggled while them while husband was working the thermostat. Boom! He soldered the connections. All good!
