I am having an issue with my ac and my furnace flickering like a power surge. I know the issue isnít in the main power because I have a surge protector on the pole. I also know that the fan motor was replaced on the rv a year ago by the previous owner along with a part on the furnace which I do not remember at the moment. Iím not sure where to start to look. I am also having an issue with the furnace not shutting off I do have the switch where I can change from ac to off to furnace. When in the off position this morning the heater after being in the off position for 5 hours itís still blowing slightly warm air into the rv. All of this is on a 2007 keystone cougar fifthwheel.

Sounds like first place to start would be to replace the thermostat...or determine if it is defective.
