I "burped" my Dometic refrigerator


Recommended Posts

My domestic fridge just stopped cooling, no signs of leakage. Everything testing good on the troubleshooting guides. The opinion of the local RV  guy was that I had a failed cooling unit. That left  me with two options: buy a new unit or replace the cooling unit. After talking to Jason at Oliver and him telling me that to remove the fridge from the trailer you need to remove the door, I thought I would try to replace the cooling unit myself. I found some places that would ship a unit for $500 to $1000 and I do the install. I watched many videos and researched the work. In this research I found several people talking about burping this kind of unit, it entails flipping the unit on its side, top and allowing the ammonia mixture to reposition and displace any air pockets. Since I had to remove the fridge from its housing I thought I would try it...and it worked!  We just took a 10 day trip and it worked fine. Some RV techs said it was a wive's tale. Glad I tried it. Hope this might help somebody.

I've read about that, and I've seen a couple youtubes, but as far as I  know, you're the first Oliver owner to give it a try. Wish we had a badge for that. 

So glad it worked for you!

Out of curiosity, how long did you leave it flipped on its head?

Sounds like you preformed a refrigerant equivalent of the Canalith Repositioning Procedure. 
 

I’m  impressed. That was a bold move and I’m really glad it worked for you. Do you have any idea what might have caused the original problem?

I am thinking that I tripped the trailer nose up to facilitate dumping my gray tank, after a bit I leveled it and it sat for several months. I had seen in a repair video the the workers who were installing  the new cooling units made sure to tip them toward the "boiler" side before using. They said the ammonia could settle and not work properly.
