Pbourgou Posted June 24, 2020 Report Share Posted June 24, 2020 My Dometic RM2652 RV fridge will not turn on, I have lights inside the fridge, but no lights on the eyebrow panel inside the camper at the top of the fridge, any help on what this could be would be great, thanks.

oldjohnt Posted June 24, 2020 Report Share Posted June 24, 2020 (edited) For starters here are basic operation manuals plus a troubleshooting manual, I'm occupied now (company coming) but will check back later to see if I can help. Insure there are no blown glass fuses on the control circuit board and battery voltage is adequate. Check the voltage in the rear where the 12 VDC power circuit is attached. I forget where the cable attaches to the eyebrow panel, see if you can find it and all is tight and in place. http://bryantrv.com/docs2/docs/operating/2652operation.pdf http://www.dave78chieftain.com/RVFridgeLibrary/Dometic/RM2612_tips.pdf John T Be back later if I can Edited June 24, 2020 by oldjohnt Quote Link to comment Share on other sites More sharing options...
Pbourgou Posted June 24, 2020 Author Report Share Posted June 24, 2020 No blown fuses, cables are tight, and as mentioned, while on battery power fridge light comes on when the door is opened Quote Link to comment Share on other sites More sharing options...
Kirk W Posted June 24, 2020 Report Share Posted June 24, 2020 Did you check the fuses with an ohm meter, as it can be difficult to tell if a fuse is bad by just looking. You can either remove the fuse and look for a 0ꭥ reading for a good fuse or you can measure across the fuse with power supplied and a good fuse will measure 0V and with an open fuse it will read 12V or whatever the supply voltage is. The service manual suggests the following things to check.

Pbourgou Posted June 24, 2020 Author Report Share Posted June 24, 2020 Just visual, I will find a meter and check once I’m back at the camper, I did read about those checks in the service manual as well, I’m suspecting the lower control Board in the back since I have 12V present for lights inside the fridge, just trying to narrow it down. I’m not electrical at all, give me wood to build something, now we’re talking lol Thanks Kirk and John Quote Link to comment Share on other sites More sharing options...
JustSnake Posted July 1, 2020 Report Share Posted July 1, 2020 Hey Guys, I figured out the problem with mine and I hope this helps out someone in the future so you can get your rig fixed fast. Dometic, Forest River were not able to to talk me through this so save some money and read this! My Rig is a 2020 Wildwood Heritage Glen HL. My fridge is a Dometic DM2852RBFX. Issue: Fridge was Deader than disco. No Power at all. Solution: Blown 152 celsius/ 303 Fahrenheit Thermo fuse (Not Thermal Fuse aka thermal (hi-limit/resettable) switch) Cause: Drove home with fridge on propane in windy conditions. I know enough about electronics to be able to frustrate myself. I tested fuses, traced 12 volts, replaced both mainboard and eyebrow board and still no luck. I ended up finding a tucked away therm-o fuse tucked off of (1) leg of the thermal (hi-limit/resettable) switch on the stack just above the ignition module. Parts available on Amazon for about 10 bucks. You will need to crimp/solder in the new thermo-fuse. The Therm-O fuse comes off of (1) leg of the thermal fuse. (Images attached) This is 12 volts DC. Please be smart and make sure breaker is off, battery disconnect is off, and nothing is energized. Hope this helps. Quote Link to comment Share on other sites More sharing options...
oldjohnt Posted July 1, 2020 Report Share Posted July 1, 2020 Just Snake, good information. FWIW Ive had those thermal fuses go bad on LP Gas Water Heaters but never had that problem on a fridge. REGARDLESS if 12 VDC is cut off that causes failures THANKS FOR THE INFO IT MAY HELP SOMEONE PB "I’m suspecting the lower control Board in the back since I have 12V present for lights inside the fridge" AFTER insuring its NOT any fuse or connection or a bad ground or low DC voltage problem or the eyebrow has no power CIRCUIT BOARDS CAN GO BAD FWIW Ive replaced with Dinosaur Brand and never had any of them fail John T Quote Link to comment Share on other sites More sharing options...

Poppabp Posted November 2, 2021 Report Share Posted November 2, 2021 Thanks…. But I think my fridge is shot. The therma fuse keeps tripping. I think I may have lost my chemical charge. Ugh…… Quote Link to comment Share on other sites More sharing options...
Kirk W Posted November 2, 2021 Report Share Posted November 2, 2021 Is yours also the Dometic RM2652? If it is of any help, this document is the Dometic service manual. Do you plan to replace the cooling unit or the entire refrigerator? Quote Good travelin !...............KirkFull-time 11+ years......
