Question about Dometic Rooftop RV Air Conditioner

DUO THERM Model 57915.622 runs and cools fine, but why does it drip water inside on the floor?

Are there any drains I should check? I have two units on my RV. Only one of them is dripping water.

I am not en expert at RV A/C units. I have worked on a couple before. There should be a reservoir somewhere under the evaporator coil(looks kind of like a radiator in a car but much smaller). It should have a hose or something to drain it away from the a/c unit. These very often become plugged on any kind of A/C unit. However if you choose to do this on your own, you will have to climb on top of the RV and remove the cover from the a/c unit to do this. It might be safer to take it to an RV repair shop.

    It would be safer, as would anything you got someone else to do, but this is not brain surgery and should easily be accomplished by anyone.

Why is my Duo-Therm 57908 rv air conditioner dripping water?


Is it dripping in the inside of the rv? You may have a plugged filter or the air filter is missing and the cooling coil is blocked with a mat of dirt. If its running down the outside of the vehicle you might find that the condenser coil is blocked with a mat of dirt collected while running. I would say you will need to go up top and pull the cover and inspect the coils. Be careful not to bend the fins while carefully brushing with a nylon brush. Hope this helped and good luck.

I have a Dometic P/N Duo-Therm Model #59516-531 that started running more and more to cool my RV 5th wheel. I checked filter, drain, and noticed the unit was icing up. I turned off AC and let fan run to...


It is probably low on refrigerant. You can only check this if you have a set of gauges. Otherwise, take it to an air cond company and they will check it for you.

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.

Dometic air conditioner blowing cool air


When the cooling slows down, but water is still running off, usually something is icing up. You can turn the unit off, and let it thaw, and try again. Sometimes, if the humidity is high, this is more pronounced. It sounds like you are low on refrigerant. That implies that you have a slight leak. You should have the unit serviced, and the leak repaired.

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.

Rv air conditioner leaking


I have the same problem....it is a negative pressure problem holding water inside the unit until it overflows the pan and runs into the duct system. why this occurs....I don't know....I cant find a problem with my air return, but as soon as you turn in off, the water comes gushing out the drains on the unit. I resolved this....temporarily....by twisting up a paper towel into a wick, and placing one end up into the drain tray, with the other end lying well out into the exterior case. This lets the water wick out and keeps the tray drained. I don't understand the problem and don't know what the permanent fix will be, except maybe cutting a hole and placing an intake vent directly below the unit.
