Thermostat on wall, or manual controls at AC? Did it work for you on low before now? Reason I ask, is that normally they are only a 2 speed fan ( low and high) so if it's a wall thermostat and has been changed from original, perhaps it the way the thermostat is wired.

Hello, I have a duo therm ac unit, the fan works fine in all the Fan only speeds, but when the ac is selected, the compressor comes on and the fan drops down to less than half speed. you can hear the fan...


Check incoming voltage circuit and wiring for proper gauge wire etc, and have compressor start capacitor tested, or replaced. I'm curious as to why circuit breaker didn't trip in panel when compressor causing so much current draw, that's reason for checking wiring etc to AC circuit.

RV Dometic Duo Therm roof top AC w/heat pump Model #630515.321El Serial #21631212 Yr. 2003. It is the rear unit, front unit working fine. In AC mode it is blowing hot air as if the heat pump is on. Fan...


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.

AC won't run on low speed


It may not be wired for low & high fan mode. If it always did before, then yes there's a problem.

Duo therm ac not working


Make sure the fan blade turns freely when off. Not bound up anywhere. Check or replace the fan motor capacitor.

I suspect that you have a bad selector switch for the on, off, low fan, high fan operation. If the selector switch is put into the off position everything should stop completely.
