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: duo-therm quick cool

Your compressor is trying to restart after it shuts off which is causing a power draw down changing the sound of the fan speed change. Check voltage power supply and insure that the power supply cord is heavy enough to carry the necessary load.

SOURCE: Location of Drain holes on Duo-Therm Model 630035.321

Good place to start is up on the roof. Look way under the unit (hard to see some times) along the bottom, between where the gasket sits on the roof and metal bottom of unit. Should see small round or similar sticking down from unit. There will be a hole in the side of them. Poke around with a wire or something to open them up. If you don't see water/condensation running across your roof from unit when it's operating, (usually in 2 directions, 1 each side of unit) then yup, there plugged.

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: I have a dometic duo-therm. No air coming through ducts.

I have a new Montana Mountaineer with a Dometic Duo Therm as well and experience something similar.

It appears that there are two options:
1. Open the vents in the unit and all the cold air will blow out of the AC as that would be the shortest path and the there is hardly any air coming out of the ducts.
2. Close the vents in the unit and it will force all the air through the ducts.

We let the air blow straight out of the unit during the day and then force it through the ducts at night to force it in the bedrooms. You could also open the vents in the unit part ways to get a combination.

I didn't figure it out immediatly either, but just look close at the unit and you can see that you can close the vents on the unit itself

Sounds like thermostat is failing. There is a factory set resistor that helps the thermostat keep a 2 degree accuracy. Second possibility is that you have a fan or direct airflow from the cooling system, being devirted, that is allowing the cool air hit the thermostat on the wall.

Duo Therm A/C (2009 Sabre RV) won't shut off


bad compressor relay on control board. The relay is not opening the circuit, allowing the compressor to stay running when unit is turned off. This overheats the compressor and opens a thermal disk shutting the compressor off. When thermal disk cools down, the compressor restarts under load and trips breaker.
