View Full Version : Do I have a bad thermostat?

First post here. I just bought a 2016 keystone Springdale 311re. When plugged into shore power the roof unit fan come on and off like it is on auto mode. But when I switch the thermostat to “off” position the fan will continue to turn on and off like auto mode. The thermostat controls work for everything else like turning the furnace on, turning the A/C on. But when switched to “off” of the fan is running on the unit it won’t turn off. Could this be as simple as a bad thermostat? It has a black ADVENT AIR thermostat installed. Any help is much appreciated.
