Fridge door gasket/insulation
I recently turned my 1.8 cubic foot Vitrifrigo c51is 12vDC compressor fridge off, defrosted it, cleaned and fluffed door seals, left door open for 16 days.
On restarting it, I set it to my usual spot on the dial, about 2.8 of 7, went shopping, placed a gallon of milk inside at 7:30 pm, and the top of it was frozen in the morning, despite also putting in a half gallon of warm tomato juice and some other things grocery store cold at the same time.
Usually, this setting does not allow freezing of things in the box.
I hypothesize that the cleaned, fluffed, not compressed for 2+ week door seals sealing tighter, contributed to this unintentional partial freezing of some items within. Looking at door seal, which is not really in good condition, It appears as if I could add another seal inside the current one, and have it rest on the interior plastic, instead of the metal of the fridge box on which the current seal seats. This seemingly would vastly increase the effectiveness of the air seal, but also keep the warm exterior metal box of fridge fridge from being in direct contact with the inside, across the seals width, conducting heat inside the box.
Anybody ever considered upgrading the seals on their fridge, not just replacing original, but adding an second seal inside, or perhaps outside, the original?
I've got much added extra insulation on the other sides of the fridge, and a very well ventilated condenser, but the door itself is lacking in thickness and the door seals are not what they were new, and I believe the design is a bit inefficient with metal from fridge body wrapping around to inside the door seal, conducting heat inside.
I believe much room for improvement exists here and would reduce battery draw and extend battery and compressor life. I have a solid area on the door and a flat mating plastic surface inside the current seal for adding another seal.Guess I could replace original seal too.
Just got to get the right amount of compression I guess as well as cut perfect 45's at the right length and glue edges together.
