Just recently I changed my fridge gasket and thought that might be the problem but I then switched back to the previous one but when my fridge is set to 39, I am measuring temps close to 32. The damper is opening and closing but there is some frost buildup where the damper cover is and moisture build-up on the celing lamp. I cleaned out the coils area which was very dirty with pet fur in front but still have the issue. Could the damper still be a problem or possibler a tempewrature sensor and where is that located?
