Did you seal outside vents after Residential refer install?

Given the statistics of propane refrigerators causing RV fires, I am surprised that anyone would consider blocking the air flow design in an RV.

Some residentials place the condenser on the fridge's side walls, instead of having a finned visible heatsink one can easily vent.

Besides extra insulation, proper venting of condenser it the best way to increase efficiency, and also the easiest way to ensure poor performance if not vented properly.

Mine DC compressor fridge sucks coolest possible filtered ambient air and pushes it only once through condenser, across compressor and controller then out of the fridge cabinet entirely.

I closed top and bottom and provided proper clearances required by manufacturer. I can still remove my outside plastic grill to access cord etc. I also have no holes in the walls or ceiling in my home around that residential frig.

The folks who installed our Samsung residential last year completely sealed all of the old vents. Seems counter-intuitive to me, but no problems so far. They said that's the way it should be done. Since they do a lot of that type of thing, I figured they knew what they were doing.

I completely sealed off the lower vent and left 1/4 of the top vent open, vents are both on side of trailer. Under the front of the fridge I have a 1 1/2" gap that I put a vent cover over. The fridge can draw in cooler air from the inside and vent the heat out of the top vent. Seams to be working well. I used Gorilla tape to seal the inside of my vents.

I custom tailored my vents to provide the ultimate in convection. The register at floor level and left the original stack flue vent. One of the things that works well is to put a very very very low CFM 120vac muffin fan blowing upwards from the bottom of the condenser. It reduced my 24vdc daily amp hour consumption by >10% and that ain't peanuts. It would do similarly with AC kWh. Less compressor run time.

I sealed mine. You should end up with enough free air space around the coils of the fridge to allow cooling. Some of that is dependent on the model of fridge you have and clearances involved. Leaving the stack vent open on the top will surely ventilate the space. If it was mine, I'd probably close that up or restrict the opening. I do some camping in the Winter so having a big opening anywhere isn't a good thing.
