Dometic roof top ac just clicks. Tried new thermostat. Same result.

SOURCE: 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)

hi,
you have to run a contractor grade extension cord(10-12 gauge) from your rv to run those or theyll do that, the lower the gauge the better, best bet is to plug the rv directly into the outlet, if you cant, get the shortest and thickest extension cord you can.

Check your furnace for power. will be 4 wires. power ground and 2 thermostat wires. Check for power at the time delay relay, if you have power there check for power going in the fan motor, if power in motor wire, motor is bad. If no power in motor wire and power going to circuit board take the 2 thermostat wire apart and wrap the 2 together comimg from the thermostat. Fan will stat in about 30 seconds. If it does you need a control kit in the ac. But sounds to me like you have a furnace problem.

pls check compressor capacitor and compressor termonal connection start the unit check the voltage at the compressor terminal if is ok means copmressor need replcement

SOURCE: Older Penguin roof shroud, new style fit?

I just replaced my two 620315.321 shrouds with the newer style without any problems. I went to the Camping World site (and called them) with model no. and they knew what to send me. I also found that they had the best price at $79.00 (member price) with free shipping.

I didnt check your shroud part no.s, but think you will be ok if you do as I did.
