Have a new 2009 Damon Challenger with a "sick" Dometic refrigerator. Problem is that as inside temp in coach increases so does temp in the freezer and refer. For example- yesterday with a 6:30 AM inside coach temp of 60.2F freezer temp -2F and refer temp of 50F. Through the day inside coach temp increased to 85.8F by 4:00 PM with freezer temp increasing to 40F and refer to 66F. Earlier this week entire refrigerator was replaced with no change in this pattern. Currently running a test with AC operation with both shore power and then generator. Currently on gas operation. None of these power sources have changed the pattern. Tomorrow, the coach goes back to the dealer to "try again" to isolate the problem. Refrigerator is in the galley slide. One theory at this time is "possible venting problem". Anybody have any thoughts on what the cause of this perplexing problem might be. This is our third motor home, all with Dometic refers, and this is a first for us. Any input would be appreciated before I resume the saga with the dealer tomorrow.
