My living room AC stopped cooling in my 375RES; was running great until high humidity with remnants of tropical storm came thru Illinois on 6/9. Bedroom unit still working. Not sure if that had anything to do with it. Went on rooftop and checked coils & fins and all pretty clean. Also cleaned inside filters. Ran Hi fan to melt any icing. Any ideas how to get cold air circulating again? Thx!

Hey Dave - You made it to the forum. A big hearty welcome to you and Stephanie.
Dave and I used to work together at the rocket factory He called me this morning regarding this failure and I was at a loss for how to approach it.
Can any of you trouble-shooting gurus point him in the right direction?
Thanks,

From your post it appears you did that--is there "full flow" coming out of the unit?
Only other possibility I can think of is pedestal voltage. Seems like a remote possibility, but do you have a way to validate the voltage levels and monitor what happens when the air conditioner attempts to start?

According to the manual, Should icing-up occur, it is necessary to let the cooling (evaporator) coil defrost before normal cooling operation is resumed. During this time, operate the unit in the “HIGH FAN” position with the system at maximum air flow. When increased or full air flow is observed, the cooling coil should be clear of ice.

I found this video interesting, though since the RV Works guy is working on a Dometic the components won't be in the same place.

Guys I as well watched that video and used it to check out my 2020 GD reflection 287RLTS which uses a coleman mach 15. It all tested out good and I also believe that the compressor has leaked out and will need to be replaced. Problem is I live in it full time in West Texas and cannot return it to the dealer. Also read that it HAS TO be returned to a coleman dealer for warranty. But I see these posts where Mobil RV techs do these warranties, how do y’all get around this? I cannot move my RV at all for now. If I have to install a new AC and it’s not a warranty I am thinking about these mini splits everyone is using now. I’ve read they work way better. But any info to help getting this warrantied would be much appreciated. I’m disgusted that it’s already bad. I only moved the unit from Dallas to west Texas one time and that was in March. So is this short time frame the unit is damaged. Coleman has made great products in the past. I have a Mach 8 in my Casita that still works like the day we bought it. Thanks guys
