Dometic 2 door 3 way fridge not cooling...

[formerFR]

Dometic 2 door 3 way fridge not cooling in the fridge, but the freezer works just fine... 120v power no problem.

is there a 'cavity' or connection between the two areas that could be clogged?

or
how does the 'thermistor' temp sensor work? What does it tell the fridge to 'do'?


thanks : )

Are you sure it's a 3-way fridge because Rockwood only puts 3-way fridges in the popups and A-frame trailers. And your trailer is neither one of those.
What brand and model number is it.

sorry, it's a two-way, with constant 120v power - and the freezer works perfectly, but no matter when the 'thermistor' sensor height is on the fridge section, it's not cooling now, even though it has been for months.

Since you have been having problems with your RM-2652 refrigerator for quite some time, (reference this thread: https://www.forestriverforums.com/fo...er-210854.html), have you disconnected all the terminals and reinstalled them? If there is oxidation on the pins and connections doing this can reestablish a good connection.

Other than that maybe it's time to break down and buy a new control board and possibly a new thermistor. Dinosaur Boards Dinosaur Electronics Home. High quality circuit boards for RV appliances. make great replacement boards. They have a cross reference chart where you need the number on the board or a list by fridge model number. https://www.dinosaurelectronics.com/Dom_Chart.htm

Have you followed the troubleshooting procedures in the service manual I sent you back on 7/12 in post #26?

I had the same problem you’re having with my Rockwood. It was at the dealer 3 times and they couldn’t figure it out. Twice we had to throw out all the food in it because they thought they fixed it. Finally i figured it out. I noticed that the flap on the left door wasn’t flipping to seal the doors and there was a 1/2” gap that let the cold air pour out. It still took 2 more dealer visits to get it adjusted right.

o.k., we've solved the recent problem...

history: bought the used RV back in June, fridge and freezer worked perfectly all that time since

recent: fridge lost cooling, freezer seemed to be working just fine



SOLUTION: I realized that recently while 'winterizing' much of the RV, and having put insulation batts behind each outside compartment door, I had also had the 'brilliant' idea of also putting insulation batts behind the fridge's outside vent cover.
I now realize that this is a mistake, as RV fridge's need air flow...

when we removed the insulation yesterday, the fridge today is suddenly COOLING just as it should be....solved.

Thanks for letting us know what you did wrong to cause your problem and what needed to be done to fix it.


I know you had been having problems with this fridge back in July and I sent you a couple of owners manuals along with the service manual for your specific model. https://www.forestriverforums.com/fo...er-210854.html

In the manuals it says not to block the vents in any way.


It seems you have another problem, reading and understanding information others give you.


I'm done.....

yes, I certainly accept the blame here... I think my 'reasoning' for adding the insulation was from the other RV we own, my son's camper, which we replaced the small RV fridge with a much larger apartment fridge - 120v only, and no longer needed the outside vent. I insulated his the same, and apparently thought that since this other RV fridge was 'only' using 120v power all the time, insulation behind it wouldn't matter, either. Wrong. : /
