Hi, I'm fairly new to this stuff but recently or Dometic DMR702 would not work properly. The Freezer would get cold and freeze, but the fridge part did nothing. We tried changing it from electric to Propane, form high to low then medium, all with the same result. My wife had been trying to start it while I was at work and when I came home I noticed a brown streak across the front white inside of the Freezer. I noticed that it had transferred also to the door. When I touched it, it was extremely hot.
We turned off the whole unit and used a larger ice chest for the weekend. I have tried to contact Keystone regarding the situation but have yet to receive a reply. Service people wanted $250 just to come look at it and one on the phone just said, "it's gone, you need a new fridge."
Has anyone had this happen?
What did you end up doing?
The trailer is only 5 years old, I didn't expect this already.
I would appreciate any help that you may have from dealing with this type of issue.

Welcome to the forum :wlcm:

It does sound like the cooling unit has hit the trail. Take the lower access panel off and make sure you DONíT see any yellow powder. If you do, leave it alone you need a new cooling unit.

If you donít, then turn it on (either will do) and wait about 20 minutes. After 20 minutes, CAREFULLY feel the chimney and make sure itís hot. Then move over and feel the coils and lower tank. If the top of the coils are hot and the bottom tank isnít warm you probably have a blockage. You may get lucky by tapping the coils with a rubber mallet, but Iím leaning towards a failed unit.

You can get rebuilt units for less than the cost of the fridge, or you might consider changing to a compressor style cooling unit if these people have one that fits your model.
