Question about Dometic Rooftop RV Air Conditioner

1 Answer

Remote does not make the a/c or heat come on

I have a 2006 Landmark 5th wheel. Everything ran well until I ran out of propane last night. Now the Dometic Duo Therm (heat and a/c) remote seems to work alright and the unit's light indicates that it is on, but nothing happens. I put new batteries in the remote, but still nothing. I now have 2 tanks of propane, but still nothing. I have read the instruction sheets for the remote and re-set everything, but to no avail. Also, the unit was beeping before when I changed temperatures or modes, but I don't hear the beep now. I have checked the breaker and the fuse but they appear to be ok. Is there anywhere else that a breaker, fuse or re-set button may be? As of now nothing works on the unit - not the a/c, heat or even the fan.

The infrared transmitter is the remote control. Do you have one ?
If so, first replace the internal battery. If this does not help you would have to buy a new remote .

It may be your thermostat, but try this first to see if time delay relay may be sticking. When it won't shut off, turn propane off, and go outside and unscrew the 2 screws that hold your cover on, and lower the cover down. Look straight ahead, attached to the housing of the fan up near top you'll see a square relay (time delay relay) with 4 male spade connectors, and wires attached to each. It's usually held on with 2 Philips screws. Give it a little rap with the handle of a screwdriver or similar a couple of times, and see if fan stops running. While your there as well, pull the wiring connector off the ignition board, and put back on a couple of times, to clean the connections. Now try it again, and let me know what happens.

Sounds like you have a bad thermostat or a short in the wiring. The clicking that you are hearing in the ceiling is a relay in the control board. When this happens, remove the face plate from the thermostat and check for 12VDC between the Blue and the White wires. If there is power then you have a bad thermostat. If there is not power there, then the problem is elsewhere. However, it sounds as if you have a bad thermostat.

Air conditioning won't work. Maybe no ground


Open your elctrical panel on your fifth wheel and make sure the wire terminals are tight comming in from the electrical power cord.

There could also be a issue with your power converter. Try turning your circuit breakers off and back on.

Honeywell propane furnace. Ran out of propane last night. Refilled this morning. Has automatic pilot. Heat will not go on. Is there air in my lines? How would I purge the lines??


You will need to cut off power
find the gas shut off at your unit and cut off.
Loosen the fitting after the cut off and open the cut off slowly until you smell gas. re tighten and turn gas and power back on.
