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.

you need to clean this section of coils badly. Get a plant or weed sprayer. go to a a/c parts supply store and get some coil cleaner. Tell the staff that you need something to clean the coils on your a/c coil. Tell them what kind of a/c you have abd they will assist you in the purchase of the proper chemicals. Make sure to read directions for the use of the chemical and also wear all necessary protection equipment, i.e. safety glasses, gloves. Follow the instructions on the chemical as how to clean your coils. Once the coils are cleaned you still may need to have the pressures checked on your unit. It won't help to check the pressures on your unit when coils are dirty since that will give you false readings. So you need to start by cleaning the coils. Good luck Dave

Dometer 3105457. how big of generator for the air


If it is a normal AC for RV then I would suggest something over 4000 watts, the AC's have a very high start amps.

You would really need to know how many amps the unit draws or is rated to draw when looking for a generator. Too small of a generator and it won't work, plus you could damage the generator and the AC unit. I would call an RV store and ask them as that is something simple for them to answer.

Duo Therm dripping water in camper when shut off. My Dometic Duo Therm Ducted AC drips quite a bit of water when shut off after running for several hours on hot humid days. The condensate lines are open....


Remove the filter at ceiling and run the AC on cool etc, and see if you can feel cool air leaking across to return air inlet where the divider between cold and return is. Check along all edges, etc for any cool air . Careful of wiring, but you should be able to get hand in there and feel especially around the edges where it should be sealed tight. Quite often a leak in that area causes cold air to enter return air and causes excessive condensation. Another thing to check is look way up inside opening for return air, with a flashlight and see if any dirt/dust on coils and fins of evaporator, and if so, needs to be cleaned off with a vacuum, and brush attachment. Let me know what you find.

I have a 2005 Pilgram 27 foot 5th wheel. My Duo Therm AC unit makes a ticking sound from the ac unit itself when it's not running. Shutting off the Duo Therm analog thermostat does not stop the ticking...


It's obviously on the 12voltDC circuit of the AC unit. Sounds like thermostat, or a relay in control box is faulty or bad connection. If you remove cover on ceiling assy., you should be able to hear it in the control box. There should be a model number on the ceiling assy., get back to me with that number and I can better pinpoint which relay. Also, try moving all thermostat buttons and temperature controls back and forth quickly to see if it may clean off a dirty circuit in thermostat as well. Make sure your AC hydro breaker is off when working with ceiling assy. just to be safe.

Does anyone know if a Duo Therm model 620515.331c is ducted or not???


The upper unit itself is not ducted. They are all the same. The ducting is done with the lower unit or "Ceiling Pack" of the air conditioner. You need to see your RV is ducted, ie...vents in the ceiling that blow the are out. Usually they are round and mount into the ceiling. Another way to tell is if the unit has a wall mounted thermostat.

Hope this helps,

Jeff

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


Sounds like the ducting have come apart in some areas or blocked in some way. Take the supply grills off and with a shop vacuum try and reach as far as you can.

RV Dometic AC Comfort Control Double EE Problem


I have a dometic duo-therm. The unit works great and fan blows strong and both high and low work., but air is coming out of the ceiling unit rather than the duct work. The bedroom unit works OK, but the air is strong out of one duct, and not much comes out of the others. The front unit only has air coming out on the A/C unit and none out of the ducts.
