OK, check out the burner area for yellow residue. A coolant leak can occur in a few places, but the burner area is more common.
Here are some pics of a failed Dometic RM2652 in a 2007 T286SR. You have to remove the recall metal shield to expose the burner area. This shield to the right with the big wiring diagram sticker on it. Assuming yours was in the recall and was corrected.
Once the shield is removed, you may see some yellow residue. Looks like this.
It may not have leaked this far out in the open. Take the small screw out that holds on the burner cover and wiggle the cover off. Then if it is there, you should see it. Looks like this
And when all apart, like this.
If your barn is vented to outside, the smell may have evaporated off but the yellow residue should still be there until it gets cleaned off. Try not and get the yellow stuff on your hands. It is sodium chromate, a rust inhibitor.
If the cooling unit has not failed, we can drill into the electric element tripping the breaker. But first, it should run and cool on gas and that is what started all this. Why does it not cool on gas?
While your out checking, get a model number off the fridge. It should be inside the door area. Or is on the newer ones. And any pics help too.
