Question about Dometic Rooftop RV Air Conditioner

AC Kicking OFF Breaker

I think I have a simular problem as above.

My Duo-Therm unit operates fine at all Fan Speeds w/o AC (Cool) selected. However, as soon as I go to any "COOL" setting, unit kicks the breaker off.

To be fair, the unit hasn't run in awhile, that I know of. It's a 10-15 year old.

Sounds like you have a problem with your compressor. If the beaker trips the second the compressor tries to come on hen it is shorted. If it takes a couple of seconds, then your compressor is locked up.

Duo therm ac trips breaker


When compressor for cool tries to kick in, or even when fan only used?
Try it on fan only, not cool, then try cool and if you hear it sort of "moan" then breaker trips, that's compressor trying to kick in. Make sure you have sufficient power coming in to trailer as well, without long extension cord. Get back to me, then I can tell you which way to go from there.

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.

Can you please reply with model number off bottom of upper (roof) unit. Should be able to see it when filter is removed from ceiling assy. Please include model of thermostat if possible. You say fan works, but when turned to cool, no compressor kicking in? Try shutting unit off, and turn off breaker at panel as well, give it a few minutes and retry and see if anything changes and let me know.

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.

The unit will draw more current when hot. Check rating of the breaker against the rating recommended by the manufacturer.

Duo Therm compressor tries to start and kicks out


I don't think these little units have a start capacitor but what I would do is check that the on/off switch wires to make sure they aren't loose. Also check the wires to the compressor for loose wires as well. It is possible that these are the first signs that the compressor is about to fail. They also can act up some when they haven't been used for awhile and then you try and start them up. Try running the unit for a few hours without asking it to cycle. It might just be a sticky valve.
