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.

Ac unit runs, inside blower shuts off after 2 mins, compressor continues to run, t-stat still calling for cool


My central AC unit decided to stop on the hottest day of the year. It would start and run normally for a few minutes and then the blower would shut off. After checking the breakers, thermostat and overflow shut off (did not have one) I saw something about a blower motor capacitor. This was easy to get to and replace and my last hope before waiting for someone to come fix it. The capacitor cost $4.04 with tax and had my AC working again. Needless to say I was beyond happy. I hope this can help others with a similar problem.

if it is a programmable thermostat you can unhook thermostat and when it comes on select 3 instead of 1. As it sounds as though it is short cycling this happens in older houses with drafts. Hope this helps Tim

Throwing breaker


Throwing the MAIN BREAKER should not happen. Calculate the distance to your main box. Tell me the wire gauge or breaker amperage. Whatever you do, do not get a larger breaker! If its a breaker on this unit Its probably doa with current leak possibly. DO NOT USE fire hazzard IF SHE TRIPS!!! let me know if its your main breaker inthe house. Hopefully you dont have crappy cloth wiring.

My duo therm roof top camper air conditioner just shut off and will not come back on. Can hear a click when turning on now but nothing else. Note that heater will not come one either.


The click that you are hearing is the relay control board in the rooftop unit. This means that you are getting 12V to the board. It sounds like you are not getting 120V to the AC unit. Check the breakers in the breaker panel to make sure they are OK. If they are fine, then turn off the AC for 5 to 10 minutes and try again. There is a thermal protection device in the unit that prevents you from turning it right back on after a shut down. Try putting the thermostat to fan only operation. If the fan does not come on in fan only mode, then you have thrown a breaker.

Hope this helps,

Jeff

We have a Coleman 7300 rooftop ac unit. When the


The fan motor is getting hot and going off on the internal overload in the motor.
This is caused by either a low voltage, a bad capacitor, or tight or dry bearings in the motor.
To check the bearings turn the power off to the unit, then spin the fan blade if it spins freely then the bearings are ok.
To check the capacitor you will need some kind of
tester or you can buy a capacitor and replace it, that's what a lot of people do. They usually don't cost very much.
To check the voltage you will need a voltmeter and measure the volts at the unit.

Circuit Breaker and Dometic Rooftop RV Air


Its the watts you plug in too like ither 30 watts vs 50 watts. 30 watts will cause your wires to get hot in the unit. just pull down your breaker box and look at those white ground wires.
