For example, on our Norcold, the installation manual recommends adding insulation batting in the spaces on the sides and top and also has specific recommendations for baffles to be added to the inner wall of the B190 to make sure that the air flows properly across the heat exchanger coils.
Airstream did not take either of the above measures with the factory fridge that was in our B190 previously. So I did them during my install of the new unit.
Thanks. I’ll look into that. There was definitely no insulation around the unit, which I plan to add. Even if it doesn’t help the fridge, it’ll help keep the interior of the camper more comfortable.
Which Norcold did you use? N305?
I also added window screen to the back side of the upper and lower ventilation grills to keep wasp from building nest in there.
Good idea.
Our unit works great on propane and 120 volt when the vehicle is stationary. We still have to watch it closely when driving. My guess is the airflow down the side of the B190 can sometimes interfere with the normal convection cooling on the back side of the fridge.
That’s interesting. I didn’t think it would matter what way the air is going, just as long as it’s being removed from the coils. In addition to the convection issue with the side vent, I think our fridges are also at a disadvantage due to being right over the tire and axle - lots of sources of heat right under the fridge.
After cleaning the dust off the coils, I set the fridge up on our deck, which gets late morning and afternoon sun. After two hours in the shade, the freezer was already below freezing. The fridge portion was in the 60s, but it had only been two hours. If there’s a blockage, though, it seems pretty clear it’s in the fridge section.
