Something wrong with your thermostat, but if you are using a electronic thermostat and have the indication of supply like light in your control then you can replace the miniature relay that triggers the cool mode of the unit. But no indication of supply try to check the fuse, then if not works you to replace new thermostat.

SOURCE: I have a dometic duo therm roof ac unit that is

It is a closed system, (ends are soldered) that said, a heating and cooling guy may be able to install fill valves and re-charge for you, but make sure you get a quote ahead of time. How old is the unit? Not normal for them to need re-charge, and I've seen them work good for 15 years, if maintained properly. Has it been completely cleaned recently?

SOURCE: RV Dometic Duo Therm roof top AC w/heat pump Model

If the Air comeing out is the same as the temp inside the RV make sure the compressor is running and not just the fans. It could be low on freon. If freon is ok then you would need to ck the wiring to the selector switch for a short. It would be obviouse because there will be melted wires. I am leaning toword low on freon since you have already been inside the wiring/control unit.

Installing rv roof airconditioner heat strip


I see what you see also in the manual. The difference is the Heat Strip package that part is optional and the 600212-001 with the optional heat strips becomes the new 600315-001 I talked to Dometic Duo-Therm and the models are the same but they both are not heat pumps but the new heat strip package comes on when told to go into heat mode when you change the thermostat to heat. The part you purchased will fit both model numbers you listed for your roof top air conditioner. Thanks, Sea Breeze

Duo therm penquin 630215 went out, replace with what??


Actually thats a, Great Idea. And far Less Expensive.

1: The only thing i suggest is, Remember that a "Thermostats" Job is to Sense when the Temperature in the room is satisfied it Kicks off the Compressor, That is its Job.
2: The Front is Desinged to Cool Just the Front Area.
3: You Have 2 options
1: Close the Rear door when just Using the "Front Unit"
2; If you choose to Leave the "Rear Door" Open, Just make sure the "Rear Unit" is on Making the "Front Unit" Work far less.

You will be fine
Please Rate me, Thanks George

RV Dometic AC Comfort Control Double EE Problem


I have a dometic duo-therm. The unit works great and fan blows strong and both high and low work., but air is coming out of the ceiling unit rather than the duct work. The bedroom unit works OK, but the air is strong out of one duct, and not much comes out of the others. The front unit only has air coming out on the A/C unit and none out of the ducts.
