Question about Dometic Rooftop RV Air Conditioner
Dometic(duo therm) roof top (brisk Air) air conditioner comes on when switch is turned on and stays on no matter what the temp setting. the thermostat is a dual heat and air control. the furnace works fine and shuts off at requested temp.
the thermostat has been replaced still have problem on the ac side
Sounds like a stuck relay on the unit itself. Maybe there is a short in the control wire that comes from the thermostat that activates the fan.
The thermostat probably has one hot wire at all times. The thermostat then chooses which wire to send the voltage down based on your selection. One of those wires is probably for the fan only. Make sure that it is in good condition (no bare, pinched or wires)
