I have a double sided refrigerator that seems to keep freezing temperatures in the freezer but does not retain the correct temperature in the fridgerator. If I turn the unit off and let it sit for a few days and then turn it back on, it will function properly for a week maybe two, then the fridge will begin to warm up and a few more weeks later the freezer will slowly rise above freezing. I am trying to get some feedback on what to look for first, thanks for nay help given!!!
