If your doors are not self closing, all of these symptoms will occur. Please read my above explanation to solve your issue. Your doors need to suction to front of frig using the earth's gravity. They will suction when compressor is on, because of air flow. Once it reaches its desired temp in fresh food, the freezer will be way below zero and water lines will be frozen. The frig shuts compressor down at 37 degrees and then doors fall off front of cabinet (gravity pulls them off) and warm air seeps in. It then turns back on and starts the cycle over and over again.
