Air Conditioner Dripping Inside RV

This morning I heard noise coming from the AC that sounded like debris was caught near the fan and rustling around. I took the white cover off inside the RV to see if I could find anything. When I took the cover off I found the inside of it had a pool of water sitting around the edge. I could pull down slightly on the metal ring that holds the AC to the roof and has the 4 bolts going through it. When I did this I could see signs of water. Also these 4 bolts were loose and I could tighten them with my hand. I found a drip that is coming from behind a metal plate that faces to the rear of the AC (see pic, I'm pointing at the location). It looks like there is a foam seal behind it. I think that's my main drip but the water under the metal ring is also concerning me. I took photos of the roof as it looks like the water is running off it. Wondering what the correct fix for this may be. Thanks

  • Hi,

    Remove the outer cover, and then look for a drain line coming out of the inside coil. The inside coil is probably full of water, and you might be hearing the water being blown around by the indoor fan. Once the outside cover is off, you probably can locate the round tubing leading from the inside coil to the outside drip pan. But you might need to remove the metal cover over the evaporator to locate the drain for the first time.

    It also helps to wash the outside coil every year or so with a garden hose.

    You probably already figured out that you need to snug up the 4 bolts that clamp the A/C to the inside housing about every 2 years. There is a flexible gasket between the A/C and roof surface that compresses over time. You probably still have 2-3 years left in that gasket.

    I have used a small wire or coat hanger to push through the drip tubing to clean it out, some dirt is probably in there.

    Good luck, and have fun camping!

    Fred.
  • Tighten the four mounting bolts. The gasket is getting old.
