Something wrong with your thermostat, but if you are using a electronic thermostat and have the indication of supply like light in your control then you can replace the miniature relay that triggers the cool mode of the unit. But no indication of supply try to check the fuse, then if not works you to replace new thermostat.

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 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.

Duo-therm will not come on makes clicking sound


You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. If you need any other help check out AC Repair Boca Raton we got you covered.

Have a duo therm ac and the low ac and low fan not work -


Thermostat on wall, or manual controls at AC? Did it work for you on low before now? Reason I ask, is that normally they are only a 2 speed fan ( low and high) so if it's a wall thermostat and has been changed from original, perhaps it the way the thermostat is wired.

Front AC unit will not turn on


The clicking tells me the AC(hydro) power has been turned off to it. Check all breakers, and make sure if you have another switch on wall, to change from front, to back, or to both, that it is in proper position.

A/c compressor runs, no fan


did you ohm the relays to verify a correct path? It sounds like the relay contacts are not "making" and providing a pth for flow.

I have a Dometic Duo-therm 1500 AC Model 59516.633C1 on my 5th wh


The clicking sound is usually the relays in the control unit making or releasing. When they click does anything turn on? Check the control unit that is located inside the lower unit of the air conditioner. Remove the cover and listen for the clicking sound. If it sounds as if the relays are clicking, try removing power from the thermostat and see if that stops it. There are three relays on the board, one is the compressor, one is the fan relay and the other is for heat. See if you can pinpoint which one is clicking and go from there. It is either that you have a bad thermostat or a bad relay board.
