I have been meticulous in keeping the unit level within 1 or 2 degrees except, of course, when traveling on mountain roads. I have an internal fan in the fridge and 2 fans installed in the outside compartment. I do not expect to maintain 35° when the ambient it in 90s and it has performed well in the past. It always keeps the freezer in the 0°F to 8°F range but the chill box can range from 45° to 50° range.
My question is: has anyone in the group actually performed the "Burping" procedure where you invert the fridge for 24 hours? and, if so, what were the symptoms that motivated you to do it and what were the results?
I have always been skeptical of doing this, but I am at the point where I would try it if there were a chance of success. It is certainly going to be a major hassle and I don't want to do it if it won't do any good.
Thanks for any input on this problem.
I tried burping my 14 year old Dometic RM2554 in my RT 210P a couple years ago. It did not help, but I thought I would try it. Yes, it is a major hassle to do in the Roadtrek. I replaced with the same model. It has worked fine but for some reason the fridge temp went to 45-50 range near the end of our trip a month ago. When I got home a rearranged my vent fans and the fridge worked fine. Not sure the fan change did it though.
These fridges can be flaky. Sometimes it is the controls. A change to the Dinosaur board can fix the control problem. Sometimes I think it is the fridge plumbing itself. Some cool well, some are marginal. Mine is OK but I wish it cooled better.
This post describes the mods I did. One big issue with the 210 is Roadtrek did not do the vent properly. See the link below. Because I already had some investment in the ARPRV board and fans and the other mods, I decided to stay with the Dometic when I replaced the old fridge. I also wasn't up to doing the electrical upgrades needed for a compressor fridge. Sometimes I wonder if I made the right decision. However, if the Dometic dies I am definitely replacing with a compressor fridge and will just have to do the needed mods.
