SOURCE: Dometic rm7732 not cooling

Hi,

If the refrigerator isn't cool, you need to answer some questions, then see if the compressor is running.

First, answer these questions:

  • Is the refrigerator completely dead? If so, see “It's stopped completely.”


  • Is the thermostat knob turned to the proper setting? If not, reset it.


Next, see if the compressor motor is running

The compressor is a football-sized case with no apparent moving parts. It's on the outside of the refrigerator at the back near the bottom. If it is humming or making a continuous noise and your refrigerator is still not cooling, there may be a more serious problem with one or more of several different components, we recommend contacting a qualified appliance repair technician for further help.

If the compressor is not running but you do have power to the refrigerator, there may be a problem with one or more of these:

  • The compressor


  • The Thermostat


  • The overload, relay, or capacitor


  • The defrost timer


  • The condenser fan motor

SOURCE: Dometic 2852 freezer gets cold but refridge does not

If your freezer is getting down close to zero degrees (F) then I doubt that your refrigerant is low. The most common cause of the refrigerator section not getting cool (approximately 40 degrees (f)) is a fan that pulls the coils in the freezer into the refrigerator has failed. A very common failure of a cheep little fan motor. Normally that fan is behind a panel in the freezer section at the bottom. Determine where the cold air in the refrigerator section normally enters and the fan will be above there.

Hello,Depending on the age of the unit, it could have a compressor going bad on it, as the compressor gets hot the valves may not be seating correctly or may be burning out.
You may have also lost some refrigerant, but I am going to lean more to a bad compressor.
Thanks

Freezer gets cold frig is hot. I replaced theromister.did no good


If your Dometic refrigerator is a tri-power model (12V, 120V, lp gas), check all modes. It is not uncommon for these units to fail to cool adequately in 12V mode, as that mode is only for KEEPING things cold while on the road.
If the failure exists only in 120V mode, replace the 120V heating element. If the failure exists only in lp gas mode, replace the burner and make sure that the jet is clean.
If the refrigerator does not get cold in ANY mode, verify that the door seal is making good contact all the way around and, if it is, you'll need to replace the coil assembly. (They are available on eBay and Amazon at a fairly reasonable price.)

Dometic RM2652 was working fine then stopped - no lights at the control panel above the doors.


Usually there is a short in the system when fuse is blown. Check the cord as sometimes mouse can damage the cord. It is a posibility.
Check power to the electronic board.

Dometic 2652 does not cool that well. Food spoils. Placed 12V fans on fins and another on the lower portion. 46-58 degrees. No help. Replaced with circuit board #3308741.002 and no-go. I have no 12V power...


Hi


There could be leak which causes the no cooling state in your unit.To check the cooling ammonia system, the 110v heater or the 12 Volt heaters can be hotwired direct to a power source, this will check the cooling system, The 110 V is best to check. But you need a repair person to get it diagnosed.


Please get back to us if you have further query else please accept this particular suggestion.

Thanks for contacting fixya.com

Smelling burnt gasses


Make sure your roof vent is not clogged immediately. If you are in a full service park, you should be running on electricity not propane. You don't describe the gasses you are smelling, if it is ammonia, your frig is probably done for.

Ammonia is the primary ingredient in the cooling process. What happens is the ammonia is boiled and then sprayed throug an orfice. The spraying creates the cooling (heat removing) effect. If you are smelling ammonia, your boiler has developed a leak.

You can purchase replacement units to install in your present frig. Some people have success with this. My experience was not so good. I spent about $225.00 plus shipping for a rebuilt unit (with a 'core' charge). I did the work myself. I got about a year out of the rebuilt unit before I simply replaced the frig with a new replacement 3 way Norcold. My new Norcold was much improved over the earlier model and included a ice maker! It was expensive, however, at more than $1300.00. Find sources for replacement cooling units for your "Thetford" refrig at FixYa.com advertisers or through your RV dealer or in the back of travel trailer magazines.

I hope this is NOT your trouble and I hope you find resolution. Thank you for your interest in FixYa.com and please come again.

I have a Dometic Americana refrigerator that is not working. When I first turned it on, everything was fine. I left for about an hour and when I came back, there were no lights on the control panel or...


These often have a recall kit installed that has a thermal fuse in the burner area....when the burner overheats the thermal fuse shuts the hole thing down to prevent fire, the ammonia smell is probably from the cooling unit. check under your burner, to see if you see a bright yellow powder or liquid if you do, your cooling unit is for sure bad and is dangerous to run. The thermal fuse shuts the fridge down completely and can be reset by pushing in the button in the middle.
