My 2013 dometic 1350 quit cooling on a trip. Mobil repair tech found a blockage in the cooling unit. He suggested we removed the fridge and turn it upside down to burp the cooling unit. We did that and turned it right side up after a few minutes. The fridge started working like normal. My question is and which the tech couldn't answer, is this a permanent fix or will the blockage show up in the cooling unit somewhere else.
Anyone had this done to their fridge and did it fix the problem long term?
thanks

temporary at best. just moving the blockage so it can show up some where else or the same place later. best be is to just replace the cooling unit on the back of the fridge if you want it to be real reliable.

Like many things in life, some are luckier than others. It may only work properly for a short time, or if you are lucky, it may work for a long time. Only you can decide, should I just replace the cooling unit now, while convenient, or wait till it quits again, at a time I really need it.

Another thought, is why did it have blockage? Most times from operating off level. In the future, try to keep the trailer closer to level, while running the fridge.

I've found that the average life for Dometic RV two/three way absorption refrigerators to be around 9 to 14 years depending on the use/abuse cycle. Living in the RV full time or not using it at all, parking way off level, failing to keep the burner can/vents clean, operating in extremely hot/cold temperatures, and a lot of off road use (bouncing around), tend to reduce the life. Some units make it over twenty years without major repairs, . . . . but, not many. Do you feel lucky?

There is no such thing as a permanent Fix. Sooner or later either A: it will happen again or B: something else will fail.

NOTE: This statement also applies to replacing the cooling unit (Or the entire fridge) Sooner or later the new unit will also fail.. Unlelss it gets lucky and some nice semi driver totals the RV as happend to me (The new cooling unit did NOT fail..) (Note.. it really turned out to be a good thing as other thins were about to fail..but did not.. quite.. due to the insurance payment.. .I can't believe the issues I found during cleanout).


Home was where I park it. but alas the.

Thanks for the responses. I guess I'm trying to convince myself to gamble with the burp thing. However, my better half says get a new cooling unit. BTW the fridge is still working like it should, but it's parked at the house.

You haven't stated HOW MUCH you DEPEND on your RV for the necessities of life. IMO, if it's a vehicle that you occasionally use to venture into the wild blue yonder and you have many options available to you, I wouldn't hesitate to take a chance on it. (It's not that hard to fix if/when it breaks, it's just $$$) But if you (and others) deeply boondock regularly and ALL your favorite perishable foods are stored there, . . . . well, I would replace it tomorrow. (at least the cooling unit if there's no other physical damage)

We are selling our house and plan on living in the 5th wheel until we find a new house. No idea on how long but could be several months.
thanks.

Sal at Kool Fun and I spent a lot of time tracing down blockage issues with Dometic and Norcold. Since he built absorbsion cooling units and was a warranty station for OEM he was no backyard boltstripper.

We filtered out manufacturers welding SLAG from cooling unit media. Could be slop right out of manufacturing UF ring or broken loose later.

Before hassling with removal try shutting the unit down for several days. If it then operates normally Slag is percolating slowly but surely up through solution and will re block the same orifice.

Aftermarket replacement cooling units did not exist at that time so I have zero information about their success rate.

I do know with giant lithium bromide chillers used for mass cooling the manufacturers spend an enormous amount of time and resources flushing and reverse flushing their production line products. Violent velocity scrubbing to remove manufacturing welding slag.

Again remove the heat from your RV refrigerator and let it sit in place for several days then try it.

The practice of "burping" absorbsion refrigerators began 90 years ago with Servel brand stand alone units. They were made in Sweden with much thicker high alloy Swedish steel.

Hope this helps

The blockage was where the dimples are at the top. Afer the burping its working fine. I did turn it off and let it sit for 24 hrs, turned it back on and it again working normal. Oh the unit is out of its cabinet and sitting on living room floor.
The unit if probadly 10-11 years old and this is first problem.
appreciate your response.
