Thermostat

[J. Ingram]

I have a 35' winnebago sightseer. The thermostat in the living room that controls the heat and a/c does not have power to it. This happened when I first bought it and the repairman said I had a loose wire. I didn't ask where it was located and now it seems to have happened again. I have checked all the places I can think of. Does anyone have any suggestions as to where to look? I would appreciate it.

Many thermostats have a fuse on the circuit board.

The air conditioner unit is powered and the T'stat wiring pickes up power from there. Be sure all control wiring has good connections. Check the wiring at the unit for 12 volt dc to controls and 120 vac for operating motor and compressor.

I checked the fuse and it is o.k. There is no power to the board. Are you talking about the 12v power coming from the air conditioner itself. I don't understand where it gets power.

You don't indicate what year your Sightseer is, but the RVP thermostats are known to fail/go dead. That would be my first guess as to what the problem is. I have replaced mine once, and know other owners who have replaced theirs several times.

The 12 vdc is sent to the T'stsat from the air conditioner unit.
