Hi my name is Robert...
This could be the circuit board inside the AC unit if it is not shutting down. What you can try to do is remove all the AC and DC power, dis-connect from shore power and disconnect the battery for about 10 mins and then see if the thermostat will return to normal operation, if not I would have a shop inspect, just to be sure I would make sure I would make sure the shop has a test thermostat to make sure it is not the problem, normally when this happens it is a relay on the circuit board inside the AC unit, the relay is part of the board.... Hope this helps some... Robert
