Sounds like the unit either has been miswired from the beginning or there is a stuck contactor relay.

The more rare scenario is that the control wire between the t-stat and the contactor is shorting to a power source causing the relay to energize. Good Luck!

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.

Dometic roof top AC unit compressor turns on even if T-stat is off. Only way to get the compressor from turning on is to turn the breaker off. Unhooked T-stat wires to see if issue was there but the...


Sounds like you may have a couple of problems there. First, have you checked incoming voltage to make sure you are getting 100-120 VAC at the AC control board in ceiling? If that's ok, try removing/disconnecting Ac compressor wire at ceiling control box and see if compressor shuts off then. May be a capacitor for compressor going or shot, and possibly relay in control box sticking, or bad wiring to thermostat. Have you had any lightning in the area prior to all this happening?

I have a dometic air/heat roof conditioner. When it is plugged in to power source, it automatically stays on and won't turn off


I agree with other answers here indicating that it could be a stuck relay contact. These units are controlled by a series of relays opening and closing contacts that apply the voltage to the compressor and fan motors. If both the compressor and fan motors are running then I would seriously suspect the main power relay is either being held ON by a stuck relay contact or the t-stat or relay control assy board has malfunctioned and is holding the main power relay in a state of constant activation. If you can disconnect your t-stat completely from the circuitry [it usually will have a connector behind the t-stat that can be disconnected] and the unit still continues to run; that would indicate to me that the t-stat is good and the problem is a stuck relay contact or the relay is being held ON. Now, after all of that, unless you have a complete schematic diagram of the t-stat, external relays and relay control board, AND have the knowledge to troubleshoot with the schematics, take it to a dealer who knows what they are doing [and all of them do not even though they may think they do]. Good luck--

A relay in my rooftop model 57915.33 chatters intermitently and trips the shore power breaker.


The reason the lights are not flickering and breaker not tripping when 6 pin harness disconnected that goes to roof unit is because the compressor and fan are disconnected, which would be the major draw that causes it. There is a few ways you can narrow down the cause, or defective relay, but my guess is if it's causing lights to flicker and breaker to trip, it's on the compressor circuit. The fan coming on and off unless capacitor faulty wouldn't draw it down that much, and obviously capacitor is good otherwise it wouldn't operate good when turned on normally. I'd start by inspecting wires to and from thermostat for possible rubbing or touching against one another at a bare spot perhaps. Can't rule out 100% that thermostat isn't defective as well. When thermostat set to cooler temperature, and on, does it turn off and on in normal cycles, to maintain temperature?
