Dometic DM2652 fridge not working

[p598738]

Was on the road two weeks ago and everything was fine. I am getting ready to leave for Florida and the fridge is not cooling. I put it on auto for several hours and got nothing. I am attached to shore power. The light in the fridge comes on when I open the door. Hoping it is an internal electrical problem, I switched to gas. Frige is turned on and switch set to gas. I can hear the flame burning. So far, nothing. Any suggestions ? Thanks.

Good news!

Now remember.......if rig is set up off level DON'T turn fridge ON
It's OK to be off level as long as you DON'T use fridge OR operate slides if any.
Everything else is OK off level.........you can run furnace, use water heater etc. Just NOT the fridge.

I moved the RV to a level area. I'll check to see how it's doing later in the day and post. Thanks for the advice.

While your home refrigerator has a compressor to compress the cooling medium; RV refrigerators use the absorption method. The fluid is heated either by propane or an electric heater and turns to gas. The gas rises up the tubes, cools and turns back to a liquid absorbing heat. The liquid falls by gravity back to the bottom and is reheated and the cycle repeats. There are no pumps involved. Off level and the fluid does not have a straight flow back through the tubing.

Level doesn't matter concerning shore power, battery power etc.

BUT IT MATTERS when operating fridge.
Absorption fridges use gravity/heat to cause cooling medium to properly flow.
Off level operation will cause improper flow.....insufficient cooling whether on electric or propane.
This can cause crystallization which will cause blockage and KILL the cooling unit.......Damage is accumulative!

x2. if it's not level enough for you to sit, walk, sleep in without noticing the "off level" the it isn't level enough.

check to make sure the shore power 120V breaker hasn't tripped.

You can not adjust temp control.......your fridge has a pre-set temp control that is for both electric & propane. The thermistor in food section can affect temps (6-8*F).

The freezer section has to cool down first before you will see any cooling in the food section
This can take several hours.

You do have the RV 'level'....correct?

I think the thermo is only for the cooling part of the fridge (not the freezer). The outside temp is mid 60s (here in Maine).

What is the outside air temperature?

Make sure the thermostat didn't get bumped

I think it was on electric overnight. I am going to leave it on gas tonight. Thanks.

How long have you had the fridge turned on? It can take a good 8 - 10 hours to cool down!
