Question about Dometic Rooftop RV Air Conditioner
My duo-therm ac will not shut off the compressor when i turn the selector to the off position on the thermostat on the wall, the blower motor will shut off but not the compressor, as a result at night the evaparator will freeze up
Do you have a wall mount thermostat? Thats what I would look towards first since its easy to get to. Don't let your compressor run with out the fan you can burn it up. I would just use the breaker as an on off switch intill you can get it looked at.

The relay board is exactly what the problem was, thanks "Guest" The 12vdc relays are normally closed and before I replaced the board I was getting a 6vdc to 7vdc reading on the (cool) leg at the thermostat with the breaker off.

IT NEEDS A RELAY BOARD IN SIDE
