Dometic RM4805 not getting cold

okay just get a new fridge it far past repair

First ensure that the fridge is level. If the fridge is level and still not cooling while there is heat on the rear of the fridge, then you will require a replacement cooling unit. Give Arcticold a call 1-888-782-6665 Web site: ArctiCold Refrigeration We keep it cold

Have you tried running it without the fan? I know it sounds funny but it has to get hot (outside the fridge) to get cold inside. Shut fan off and see what happens. Also, keep in mind the more items you put in it that are already cold, or frozen, the faster it will cool inside the fridge. Also take a look up the back of the fridge, with outside cover off to make sure no big wasp nests or similar up there. May need to remove cover at roof and look down if you can't see too good from back of fridge vent.

On the back of the unit, at the bottom, there should be a panel that is removable. Inside should be a fan, the condenser coil, and the compressor. The fan has to be constantly blowing air over the condenser coil, to dissipate the heat (which it is essentially being removed from the refrigerator by the compressor)

When the entire fridge stops cooling, one of three things have happened. The fan isn't removing the heat from the coil, or the compressor isn't compressing the freon, or the freon has somehow leaked out of the system. If it is the fan, you have an easy do it yourself repair. If it is the compressor or the freon, you will probably (but not necessarily) need a professional.

Inside the fridge, there is a coil that is cold instead of hot. A fan must continually blow over that one too, to circulate the air over the cold coils. The fan usually only works when the doors are closed, so be sure to have the door switch pressed to "shut" when checking it.

Check those and post back. And, I know... it really is Dometic.


If the problem is the first one,

sounds like you need to replace the electric heating element

If the freezer is getting cold check for air flow in the back it needs to be free of any obstructions. Next adjust the sensor on fins inside the fridge it works as your temp control move it up and down for control.
