Yup, I searched the archives;

Recently I removed the fridge to install a new fan and upgrade the
insulation behind it.
When I installed the bracket for my fan I turned the unit upside down.
I had seen this inversion procedure recommended as a "tune up" so had
no qualms about inverting the devil.

Upon reinstallation the fridge the cooling at first seemed far less
effective, (a great reward for my efforts) then actually seemed to
become a heating process. After leaving the fridge on propane overnight
I noted water condensate on the outside of the vent (actually could see
some steam) and an interior temp of close to 60F. When I SHUT the
burner down the interior temperature actually went down about 6F in a
half hour as if the cooling cycle had started. The condensate had a
bitter salty taste.

I am interested in comments but here is my real question. Has anyone
actually had success "burping" the fridge? If so how? Simply invert?
How long? Or rotate through various attitudes in what order and for how
long. I'd like to hear from members who actually have done this.

I know that there are far more efficient units but I would very much
like to maintain the propane cooling option and to keep the van
original.

Thanks
