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

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.

SOURCE: 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.

SOURCE: ac blowing breaker

The unit will draw more current when hot. Check rating of the breaker against the rating recommended by the manufacturer.

need to get at the capacitor for the fan. Try spinning blower when it hums. If it runs then the cap is bad if not the motor.
