    Refrigerator takes over an hour to cool the freezer down to 5degrees from 35 degrees. the evaporator fan is running, the condenser fan is running, the compressor is pulling 1.4 amps and the discharge temperature is 105 degrees. all coils are clean and the suction line is frosting up at the output of the evaporator.

Little info to give a good diagnostic
here some hints:
1) try to defrost it
2) check the grid at the back that normally radiates the heat from the fridges cooling liquid, and undust it,
3) if it is a fridge/freezercombo, then it can be that the defrosting needs to happen in the freezer compartiment, as both sides most likely do share the same cmpressor
4) eventually your fridge lost its freon or other cooling gas.
5) could be the termostat also

Question: I have a trailer camper it has a Dometic Rm 2652 Ameri. refrig.


If I remember right on those, the system works off 12 volt--120 volt-- or propane (LP gas). have you tried one of the other power source to run it off of?? If you get the same type cooling results the problem is probably a small leak in the freon system. Those use special internal gas. When I worked for GE the only way to fix them was to replace the complete cooling system which came pre-charged with the special internal gas. Quite expensive after the warranty. Now if you switch power source and one of the other sources make it work the problem will be with the type power you were using when it failed to cool properly. Many people that had system problems with those camper type refrigerators removed them and installed a small regular dorm style refrigerator that could only be run off a 120 volt power system. You would need a 12 volt to 120 converter to run it while on the road if thats what you want to do.

It doesn't cool.


Step 1:

Determine if you have power at the outlet, if you have no volt meter use a radio or lamp etc.

Step 2:

If you have power you need to determine if the compressor is running, if it is, is the line entering the compressor cool at all? even after running awhile? assuming the compressor runs, typically it will be not running, or if running, low on refrigerant, if that is the case it will not be worth charging or repairing.

HOW CAN I MAKE 12 VOLT RUN OFF OF ELECTRIC AT THE CAMP SITE, MY CAMPER HAS A SWITCH FOR PRO AND 12 VOLT BUT NOT ELECTRIC, SHOULD IT KEEP COOLING WHEN ITS PLUGED INTO SITE ELEC?


If this box is part of an RV, the factory has probably also provided a transformer and rectifier to supply ~12 VDC when connected to standard AC mains. Switching it to the twelve volt setting should be all you need to do. If it isn't cooling, check your breaker box to see if it has tripped the breaker circuit it is on. If you find no tripped breakers, it is possible that the rectifier has failed or possibly the lousy wiring one finds mostly in RVs.
If there is outside access to the area of the fridge, open it and check for a good-sized transformer in that general area. If you can locate it, you should be able to make some measurements with a cheap digital multimeter to locate the problem.

I have an 8 year old Maytag side-by-side refrigerator that stopped cooling. The refrigerator side is not cool at all and the freezer side is marginally cool.


your freezer cabinet need to get all out and open the back wall.
  1. you have 2 element that can be check one is the heating element , two is the thermostat.
  2. you need a volt meter to check them.
  3. if the frost is all over the coils then one of the element i told you before, is bad
  4. if the frost is in one area not all over then you got gas leak.
  5. good luck 911service today .com

I HAVE A 1997 FLEETWOOD RV WITH ORIGINAL DOMETIC RM2852 REF IN IT. ALL POWER SEAMS TO WORK (LIGHTS ARE ON PLUGED IN OR OFF OF GAS BUT THE WHOLE PROBLEM IS THE REF OR FREEZER WILL NOT GET COLD


Largest problem is with the cooling unit going bad on these unit at about your units age.
But first
check your 12 volt fuses and make sure both the fuses in the back of the refer and the fuse in the power distribution panel are good
Must have 12 volt for the gas to work
