Yes mine is in a Dometic 7 cu foot in my 2014 23D. Thanks for the kind words, but I made mine also. Simple 2x3 aluminum extruded tube milled to make an air duct. Two 60mm fans inside pull air into the duct and blows it out the holes in the back of the duct. Blowing the air through the cooling fins in the back of the fridge. A 3 amp breaker two 2x3 plastic end caps and a power switch complete the project. I’ve been using mine for about 3 years now and it helps keep fridge temps low and I never have problems with icing up. 12volt power was obtained by running the 12 volt positive lead out through the drain tube and the ground is attached to one of the cooling fin screws via a eye crimp.
There is a guy now making them and selling them online called “fridge-fix”

12volt power can be obtain by running a wire out through the drain line.

GMFL - if you made that fan yourself then the guy making and selling them copied your design. Nice work.

R3100 NovaKool

I had a terrible frost/icing problem that was simply solved but it was a pretty specific issue.

The NovaKool R3100 has a reversible door that is hinged on the left.

There is a bottom bracket with a hinge pin on the right that receives the door when the door swing is reversed.

On mine, the bracket was bent up just enough to interfere with the door gasket sealing. I bent the bracket down and made sure the gasket was sealing when the door closed.

Voila...no more icing.

Something to check when troubleshooting.

VAtom - good tip. I noticed same problem on mine just before my last trip. That seal has to close tight to keep frost down.

VATOM - What MIKE said. No major icing issues here but won't hurt to check. Thanks for tip!
