roof leaks through air conditioner

[Rob Hentges]

My RV has a one-piece roof. I have two roof air conditioners (Coleman Mach III). DUring heavy rain, I now have water leaking in through the rear air conditioner. I do have a cover on the conditioner, so I think it must be a bad gasket in the roof cutout.

Is this a simple fix? I assume I can just buy a new gasket and replace it.

Thanks.

on most if you remove the inside trim panel you will see four long bolts that squeeze the inside mount plate and the outside plate together. I would first make sure they are snug, then shine a bright light up around the seal area and look for signs of water movement, you could have a piece of twig or something under the gasket,.
if i remeber right the a/c needs to be lifted up to replace the gasket.

Robert does remember correctly about the replacement of the gasket. I would try tightening the unit first, but don't over tighten as that will cause leaks.

Also the drain or hole that lets the water drain to the side may be stopped up. You have to take the cover off to check this.
