2005 Fleetwood Niagara, Coleman 13,500 Mach A/C, just fixed a/c today after figuring out it was a bad “hard start capacitor”. Now I am back to our original problem of a leak above the luan ceiling panels that is warping the ceiling. The last time this happened was two weeks ago and we didn’t notice the air conditioner had been leaking until we opened the camper after arriving at the campground and noticed the stains on the canvas’s. This could have only happened as a result of running the a/c before we closed it up prior to leaving on our trip and condensation getting trapped between the luan ceiling and the roof, then running out after we closed it up to leave. Long story short, I called a repair man to find to leak, then called insurance to alert them to the damage. The repair tech notice that the duct between the inner and outer a/c unit was not re-installed properly and was probably causing condensation which was dripping in the ceiling, funny thing is though, everything on, in, or around the a/c seemed dry as a bone except the board running down the center of the camper under the roof. None the less, he fixed the duct and it seemed to fix the issue but I wasn’t convinced so we limited the use of the a/c for the remainder of the trip and ran it on low cool and as low a temp setting as we could to be comfy to reduce the possibility of building condensation. When we arrived back home I opened the camper back up to put in a dehumidifier and noticed some more staining on the interior a/c vent but figured it was some residual moisture that was trapped in the ceiling somehow that escaped on the trip home (Georgia Roads) so didn’t pay it much mind. Now back too today, I got the a/c working again, been running it all afternoon and took the wife in to show her how cool it was around 9:30 tonight. Even though I had it on low cool and the temp turned down it was still ice cold in the camper. I reached up to check the ceiling out of habit to see if there was any moisture that came out of the area of the seam that we had an issue in before and to my surprise, there was, again, the luan was soaked. Can anyone give me some thoughts on where they think this moisture may becoming from? It is not coming from outside the camper, somehow, somewhere it is coming off the a/c. Please help guys! and if anyone has pictures are a schematic of the roof on these models I would love to see it since I-will be rebuilding this one, it is a shame too, this was an almost perfect camper and if the guys who put the new a/c seal on last summer we’re worth anything, I don’t think we would be here discussing this.
