Question about Dometic Refrigerators

1 Answer

RM 2611 On A/C power the unit goes into default and runs constantly freezing everything in the fridge. On propane it maintains 40 degrees in the fridge. So I replaced the lower board with Dinosaur board and replaced the thermistor. The thermistor checks fine at 9,000ohms when the lead is submerged in ice water. Any idea why it works fine on propane but not on A/C?

Are you sure about these temps C or F? At 2 deg on either scale, food would freeze! And -23 is unreachable.
Water running down the door sounds like a seal leak, check by putting a dollar bill between the seal and the frame. It should NOT pull out easily. Or there may be an air leak in the ice/water dispenser. Look at these parts closely. Or the "stile heater", a heater in the door frame to prevent condensation, may be broke. This is expensive to fix.

Yes. LP is direct heat to the exchanger. The thermistor operates through the control to the electric heater.

SOURCE: DOMETIC RM 1350 FRIDGE GET HOT AND COLD

Ok, I realize I'm a little late on chiming in here, is this unit located in a slideout, and/or the top outside vent is in the wall not a roof located vent?

If so then the issue is that there are fans that are necessary to circulate air thru the hot coils. And there is probably a malfuntioning thermostat to turn these fans on/off. I had this issue with same fridge in a Gulfstream motorhome, and the temporary fix was to pull the faston connectors off the thermostat and tied them together with a 12V fuse, and taped it up with electrical tape to keep it from shorting on fridge chassis and parts. Replace the thermostat at your conveniance, as these fans are now running whenever fridge is on, and will run your batteries down if not plugged into shore power.

Had the same problem. Chances are that the water has frozen in the supply tube, not allowing water into the maker. you will need to unplug and thaw out your fridge entirely to thaw it out. I used a hair dryer pointed at the filler tube to defrost it.

Replace the damper assy, in the Refrigerator section. The damper door is stuck open. Very common problem on these refrigerators.

Have a dmetic rm 2652, have power in fridge but no freezer or cold in fridge,tried restarted 3-4 tims still no good,trieda new 5 amp fuses ran 3 minutes stopped again?


On most Dometics, When you have a cooling problem follow these steps and it will resolve your problem or at least tell you what is wrong.
Check main terminal Block for proper Voltage
Check Heating element for proper ohms, 2652 is 44ohms
Disconnect P-2 wire on board for approximately 12 to 18 hrs. This makes the unit run constantly in case there is a clog in the unit.
The only other thing you may do is check the thermistor operation, Unplug the P-2, remove the thermistor from inside the refrigerator, put it in ice, You want the thermistor to drop to about 32 degrees, Check the ohms, they should be at 8,000 to 10,000 ohms.
If all checks out, you have either a bad board, not common, or a bad cooling unit, common

Freezer in the gararge redfrigerator quits working when outside temps get real cold


hello. this is a common problem. The thermostat for a refrigerator/freezer is in the refrigerator part. Normally the refrigerator is kept at around 40 degrees. The compressor turns on as required to maintain this tempearture. The evaporator coils are concentrated in the freezer side, so that the freezer stays at around 0 degrees while the fridge side is held at 40.

If the ambient temp is around 25 degrees, the refrigerator compartment will get below the setpoint of 40 degrees, and gradually continue down towards 25 degrees. The compressor will not have to run at all to maintain this. In fact, the compressor is designed not to run, once the refrigerator compartment gets below the setpoint, for fear of freezing the contents of the fridge.

The lack of circulating refrigerant due to the non-running compressor means that the freezer compartment will gradually warm up to 25 degrees.

If the unit were just a freezer, it would work fine in the unheated garage. If it were just a refrigerator, it would not run in these conditions, and the contents would eventually freeze, but it is otherwise OK.

Regards, Joe PS kindly rate my answer. Thank you.

What temp should the fridge and freezer each be?


According to FDA safetey specs bacteria can grow at 40 to 140 F degrees .Refrigeration must be below this number but above 32F to keep from freezing. I maintain commercial refrigeration and they run at 34 to 38 F degrees. I have deep freeze set at -10F which keeps ice cream very solid but can go up to +2 F which renders softer ice cream...

Fresh food side too warm


Refrigerator nguyen@ite.net 40 F or lower is the recommended refrigerator temperature to slow bacterial growth and maintain quality. Freezing occurs at 32 F; adjust refrigerator accordingly between 32 F and 40 F to prevent unwanted freezing, such as freezing milk.

Dometic fridge


I would look for a ventilation problem. If the fridge is working at that level nothing wrong with electric. The unit needs air to move up and out the top to make the freezer work. It sounds like the air is only moving the wrong way out the lower vent. Careful it could just be a birds nest but it may be a large wasp nest blocking the roof opening.

Tuna, it sounds like your thermistor is bad. Once the fridge reaches 40 degrees, the thermistor is supposed to tell the board to stop cooling and maintain. You can test it with an Ohmmeter.

To keep a constant 40 degrees the fridge would have to be running 24/7. Any fridge will maintain the 40 degrees but in your case, if you are going to be travelling, you should be looking at a fridge that can run on mains and battery power. It might even pay you to invest in an extra battery, dedicated to the fridge and charged by mains power and/or the vehicle alternator.
