In my first post I showed where my unit has been frosting over.
I have noticed that my unit is defrosting normally when the temps are between 30 and up, however once it dips into the low 20's it frost over and stays frosted over. This mainly occurs at night when the sun doesn't do its thing and help warm the unit up.
We are now going through blizzard like conditions and I just walked out and noticed that along with the snow build-up on the unit (grill and top) that my coils are seriously frosted over again. I assume this is due to moisture being present in the air. My question is should I be concerned and is there anything I should be doing to prevent the frost from damaging the unit?
