A/C interior leak on first camping trip
This is my first post to this forum. We just picked up a 2012 Forest River Catalina 29RLS and took it on its first trip this last week. For the most part, everything seemed to work as expected. The weather was extremely humid, with temps in the low 90's. We set the A/C to 76 (I've since read a post about keeping it 10 degrees below outside temp), and we selected Auto Fan High (vs. Manual Fan High). During the day, I noticed that besides the normal drips off the ends where they should be, there were small leaks coming down the inside of the skin, mostly around the rear door steps and wheel well.
That seemed odd to me, but I didn't worry about it. When I got up early in the morning, I stepped into standing water near the kitchen sink. Obviously, a lot of water was collecting there. We toweled up as much as we could and headed right for the dealer, assuming that we had a serious A/C leak.
They asked me if I was running the A/C fan on auto (shuts on/off with the compressor) or manual (on all the time). When I told him Auto, he said that this was the problem due to icing. He said if I ran the fan on manual when outside conditions are extreme, I would be okay. This explanation does not sit well with me.
I have not been on the roof yet (no extension ladder right now), but it seems odd that there wouldn't be some sort of runoff protection provided for this condition. I'm alarmed that running the A/C will continuously wet the interior of our new camper.
Is there any truth to the Auto/Manual fan "solution"? If I keep the thermostat no more than 10 degrees below outside temperature, should I find no leaks anymore?
Thank you to whoever can shed some light on this.
