Have had problems with duo therm air conditioner leaking inside camper. water dripping/pouring into floor from vent. Just replaced board and gasket...still 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.
In each of these cases I would check for proper connection of the return air vent to the A/C from below. Static pressure from insufficient return air could cause negative pressure to hold back on condensate drainage. when the unit is shut off the pressure becomes equal allowing water to drain. Also check air filter and clean if found necessary.
It probably a dirty coil. when the air passages are restricted it increases negative pressure. residential units require a trap on drain line to overcome drain issues.

My dometic also leaks inside the motorhome. I see water dripping off the side of the RV, but when I turn the A/C unit off, the water gushes off the side of the RV.
condensation leaking
we are camping in Stone Mountain,Ga. AC has been woring fine for the last week, but this evening it started to drip when it was running. when the fan turned off, water gushed into the capmer. The fan turns off but the compressor (I guess) still runs and thens blows the breaker. It has,up to this point been draining outside. Can this be due to a dirty air filter?
Water dripping inside in coach after running several hours.A/C seems to be draining outside but also drips inside. Dealer replaced the gasket but still leaks.This a/c is installed on a class B unit. Sometimes after the unit is off while driving and applying the brakes water again drips in. The pan was checked with no cracks.I notice when I turn the unit off a big push of water comes out the outside.
