SOURCE: duo-therm by dometic ac rv unit

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: Compresser will not kick in and there a electrical smell

Sounds like your start capacitor may have gone bad. If you remove the shroud, there should be an access panel for the electronics. In there, you'll see one (or two) cylindrical parts with wires coming out the top. If one of them shows signs of something coming out of it, it's probably your start capacitor and it needs to be replaced.

You can view the installation/service manual for DuoTherms here at Bryant RV.com (it's a 3MB PDF file, so download with care). Look on page 28 for info on the capacitors.

SOURCE: 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.

SOURCE: have duo-therm ac breaker will kick when temp

when it is above 85deg. it will run the freon pump. causing the unit to pull more amps for a longer time. try replacing the breaker with a new one of the same raiting. if this fixes the prob. the have a nice day. if not then you need to get it to a repair center and have it checked by a tech.

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.

9/20/09 I just had the same problem with the same model


With rooftop air-conditioning units two issues are commons and that not clean unit that slow the fan and that effect the compressor, check the fan and see if the housing clean and no debris and as far as the compressor it is don and you need to replace it, I am sorry to tell you the news but on the other hand you can get used one now very cheep and they do work good. See if you contact local dealer that serves them and ask for used one or call campaign world and ask them to look for one for you…let me know how that work for you and please do not forget to rate my service so we can improve on it with your help. God bless

AC Kicking OFF Breaker


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.
