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.

SOURCE: PROBLEM WITH DOMETIC RV ROOFTOP AIR conditioner

Check at the compressor terminals between the Red and the terminal for the overload protector to see if you are getting power to the compressor on startup.

SOURCE: duo therm air conditioner that the compressor will not start

your switch should be oopen but when it reaches 41 degrees it should open so the system shuts off before it damages the compresor by sludging it, i have the same unit and my compresor runs for 5 seconds and shuts off, i checked the amp draw at the compresor and it draws 21 22 amps trying to start after the initial 5 second run, but it wont come on againts a load so the comprresos equilizes and tries to start over again with out positive results. i bipass the external obverload on top of compresor terminals area, still no fix yet, the relay on the control board continious to send power to the compresor and still draws , so if there is a problem with the control relay i would open up and dont send power to the compresor so i dont think is the relay, i am a a/c service man for
35 years and do this for a living still today, by experience i think it is the compresor gone bad but will try by passing the relay just to see what happens, also it could be bad capacitor since it have a hard start relay and start capacitor (black )also a run (silver ) capacitor they check ok, there is no way to check the charge unles you install a saddle tap to check presures and rechage this unit i think the compresor replacement is the way to go ( around 250) plus labor and freon r22 e mail add aljpuig@yahoo.com.

SOURCE: My Duo-therm Brisk-Air by Dometic rv ac wont cool.(The fan runs )

Usually just listening closely will give you a rough idea where to look for problem. When you have the fan on and switch to cool, (with temperature turned down low obviously) do you hear any type of "moaning" sounds from AC unit, or see lights in RV dim slightly indicating that compressor is trying to engage? Is the breaker tripping when compressor tries to engage? Do you hear a "click" from AC unit when switched to cool? If none of that happens, then I'd start thinking thermostat, or compressor relay. Normally if it's a faulty capacitor, the compressor will try to engage but will make a "moaning sound" and usually trip the breaker due to excess current draw. Someone experience in electrical should be able to test relays etc, but whoever does work on it, should be aware that those capacitors, as well as hydro in general are very dangerous to work with. The ("zap",- Shock) that you can experience from a capacitor or hydro, can be fatal.

I have a rooftop ac unit on my popup that was replaced two years ago. The unit works fine but I would like the fan to shut off when the compressor isn't running. Is there a switch for putting the fan...


Please describe your controls. Does it not have low fan, high fan, low cool, high cool on the dial at ceiling? If yes, low cool or high cool setting should shut it down when temperature is reached via thermostat dial.

My a/c comes on fine; however, if the fan is on low it kicks the circuit breaker after a couple minutes. It works fine on high.


Feel the compressor it may be getting hot and the increased
air flow on high may cool it somewhat.
If so compressor problem or much slowed fan
Check air volume on low.
If this was helpful please rate me.

The fan on my duotherm a/c doesn't work. I can hear the compressor come on but the a/c doesn't blow any air. There was a fairly loud pop when it quit working. Am I looking at replacing a condenser or relay...


SOUNDS LIKE A OVER HEATED CONTROL SWITCH   THE SWITCH THAT CHANGES HIGH, LOW FAN, HIGH COOL, LOW COOL. REMOVE INSIDE CEILING SHROUD AND LOOK AT SWITH FOR BURNT TERMINALS OR LOOSE WIRES TURN OFF POWER FIRST AT BREAKER.

High cool not working


Compressors on these units runs at only one speed. The change to high cool is only a change in blower speed moving air faster over the cooling coil. I would have the running capacitor for the fan motor checked. A bad capacitor can cause your type of problem. The other problem could be that the high speed winding in the fan motor is bad. Try it operation in the fan only position through the two speeds. If it works in the low and high speed for fan only your problem could be in the selector switch.
