Dometic Frig Quit

I'm not sure what the burping process involves but I had a friend who removed his fridge and flipped it upside down a few time over a day then checked it on electricity and it worked afterward.

Blockage in a cooling unit is caused by overheating of the ammonia solution.
Overheating is caused by disruption of the gravity flow
When the solution is overheated the rust inhibitor (sodium chromate) crystallizes
When it crystallizes it plates out on the inside of tubes
When it plates out it disrupts the gravity flow which creates more overheating/more plating/more blockage.....it is accumulative 7 permanent

All the flipping/rolling/burping will NOT change that.
It may dislodge some of the blockage and allow some flow which could increase cooling BUT the blockage just ends up somewhere else.
The crystallized sodium chromate will NOT go back into solution


First thing to try.......
Turn fridge off for 24 hours.
Make sure it is level
Unplug thermistor leads in circuit board (Upper left corner P2)
Then start up fridge set to max cool and let it run overnight (thermistor unplugged causes fridge to run continuously....max cooling possible)

If fridge doesn't cool down......cooling unit is bad
If fridge cools down....replace thermistor

Okay it sounds crazy but I would lightly bang on the coils to try to reduce the blockage. As stated it's only a temporary fix, but in my case it worked for a couple of years.

PLEASE post the outcome. Thanks!

You might check around the coils and heater element for a yellow powdery substance. If there you probably have lost coolant. If so you need to have the coils rebuilt. It happened to me in a 2005 unit. Good luck and let us know.

I feel your pain. This happen to me this weekend too! I'm getting the same symptoms. Propane and electric heating work but it doesn't cool. No signs of a leak. My RV is level and hasn't moved in years. I'm off-grid and it runs on AC during the day and propane at night. I'm looking at so called Amish cooling unit as a replacement.

If it makes you feel any better, my heater went out the next day...
