I would make sure there is power to the unit before I attempted any repairs. Gas being available will not allow the thermostat or gas valve to operate if there's no power to them

There is ice forming on the evaporator coils. This is either from a low freon charge or a leak in the seals or windows and doors. Could also be that the drains are not working and water is building up and freezing

RV AC is working fine, but the water is leaking from the ceiling Where is the drain tube on the unit, The AC unit is a roof type, Duo Therm serial # 43404934, Part # 3105459


Normally, the condensate will drain out of the unit onto the roof and off the edge to the ground. Remove your cover inside (probably 2 screws) and tighten the 4 bolts you will find inside. If they are tight, go to your RV supply place and get new roof gasket. Remove the AC and insert the new gasket and resecure the AC to your roof.

Ac unit blowing water with air on after a few minutes


2 things to check, one is remove filters on inside & look at front coils to make sure they aren't frosting/freezing up. The other, remove cover on upper unit & check that drain holes in base are not plugged. Be careful of wasp nests when removing cover. If neither one of those is problem, you may have a cracked drain pan, which you can also observe/inspect when cover off on roof unit.
