Dometic rm 2193 fridge - works, then doesn't
I've got a Dometic rm 2193 in my 1996 Four Wheel Camper. I assume the fridge came with the camper in 1996. Fridge is a 3 way fridge. Seems to run fine on 110 ac. Haven't run it to much on 12v dc, but the few times I have, it seems to work ok. My problem is running it on propane.
I'm preparing for a 4 day camping trip to the desert, so I tested it last week and it worked very poorly. I pulled apart the burner, the jet and the chimney and cleaned them (cleaned burner by soaking in alcohol and blowing dry with air). Put it back together and now I get a nice blue flame.
2 days ago i turned it on high and it got down to 32 degrees. Yesterday, I came home at 5:00 and it was at 32 degrees, sitting in direct sun on a 90 degree day (it's in direct sun from about 1:00 onwards). I checked again at 7 pm and it was up to 54 degrees. I'm checking with a remote thermometer, with the remote in the fridge, so I don't have to open the door to check. The flame was still burning just fine and the tubes were all hot. I checked again about 9 pm and it dropped 2 degrees. This morning it's down to 32 degrees again.
Any ideas why it would warm up to 54 with the burner still going? It was sitting in the sun all day, so I don't think that would cause it. I checked the propane tank and it's about 1/2 full.
Thanks for any ideas.
