Duo therm rv air conditioner repair


Sounds like thermostat is failing. There is a factory set resistor that helps the thermostat keep a 2 degree accuracy. Second possibility is that you have a fan or direct airflow from the cooling system, being devirted, that is allowing the cool air hit the thermostat on the wall.

I think that I would change out the thermostat only due to the symptoms you are describing. Think the control board may be fine however, the thermostat sounds as if the internal componants are going out. Good luck on your repairs

Duo Therm Thermostat


Hi there

I think this is a setting on your air conditioner, the air conditioner will turn off when the room is at the correct temperature and when the room starts to warm up, the air conditioner will turn back on. (You need to find the settings and change them from auto-adjust to manual-adjust)

Keep us posted and thank you for using our service.

Will not shut off


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)
