Question about Dometic Rooftop RV Air Conditioner

1 Answer

A/C doesn't blow cold air

My coleman rooftop A/C doesn't blow cold air. It doesn't seem to matter whether you have the control on High/Fan or High/Cool. The temp doesn't change. The second knob that adjusts the amount of cool air is the same. It doesn't matter what setting, the air temp is the same. How can I tell if the compressor is even coming on

2 year old Coleman Mach III tapping and not blowing cold air:


Make sure the condensor fan is blowing through the condensor on the roof. It sounds like the compressor is fighting high head pressures after running a bit.. After so many attepts, or if it suceeds in operating the load trips the circuit breaker.. Make sure the condensor is clean and air is passes through it from the fan. Just for clarifiication the condensor is the coil that gets hot and the evaporator is the coil yat create the cold air. Good Luck, and if you will, let me know how it turns out. Good Luck. Ned

Fan cutting on and off every 5 mins


The only thing that is going to but the fan off is the thermostat. When the fan stops, immediately check the thermostat on the wall. See is there is power between the B terminal and the GH terminal. If none, then replace the thermostat. If there is, then replace the control board in the AC. That means that the fan relay on the printed circuit board is weak.
