RV Refrigerator not getting Cold.
after extensive research and personal knowledge this is what I did to get the refrigerator working Way Better.
(cost zero) 1. Moved the temperature sensor from third on right cooling fin to twelve on right cooling fin, this allowed the temperature to go from 50 degrees to 40 degrees in the refrigerator.
(cost $35) 2. installed exterior fans on the outside of the refrigerator, as seen in photo "outside fan" they are 2 large computer fans, zip tied to the outside cover. this allowed me to lower the refrigerator temperature from 9 to 7, still keeping the same 40 degrees. they are wired into the 12V feed for the refrigerator with a 2amp fuse, I let them run all the time because I'm not in cold weather.
(cost $25) 3. installed a smaller computer fan inside the refrigerator, as seen in the photo labeled "inside fan" thus allowing the air to be distributed, hopefully lowering the bottom shelf of the refrigerator temp to 40 degree. this was a bit of a challenge due to the power, and connecting it to the fins without damaging the fins and ruining the refrigerator. I used zip ties and the "z" clips you get at Auto parts stores to hold wire, the power wire I ran up the drain tube.
I hope this helps others, because a warm refrigerator is only good for wine!
I also noticed the "home refrigerators" get their cold air from the freezer portion via a fan and door to control the volume of cold air, RV refrigerators, have separate cooling fins for the refrigerator and freezer portion, I wonder if that has any effect?
