Clean those jets.

There is a lot of discussion on this site regarding the efficiency of absorption refrigerators. Our friend Bob Miller mentioned in another thread that a Dometic engineer told him that the refrigerators should work best on LP, followed by AC and then DC.

My Dometic RM-2193 has never worked on LP as well as on AC in hot weather, 80 degree F and above, despite my having cleaned the burner and the flue on a couple of occasions. I never cleaned the jet because it looked nice and shiny, and frankly it looked so fragile that I was afraid to pop it out. In addition, I have added ducting and a computer fan to improve air flow over the condenser fins and added insulation to the outside of the unit.

Looking on YouTube I found this short video on cleaning the burner:

Good stuff Clif. thanks for listing your experience. I use alcohol for cleaning jets and, if it doesn't help I drink some and don't worry... LOL

It is very important that a dirty jet may not "Look" dirty and, if cleaning it fails, just replace it, as the p.o. may have tried cleaning it with a wire and distorted the opening, which is a lot more than just a hole. Dometic still has them in stock. A new one brought mine right back to "As New" for cooling.
