I have a Frigidaire side-by-side (FRS26RLECSC) and it will not stop running! I can hear the motor humming and cold air being blown into both sides probably 20-30 minutes per hour, every hour. I tried turning down the temperature setting, but it keeps running. I cleaned the condenser coils and checked to make sure the doors were sealed properly. I don't have frost or any other signs of malfunction -- other than the fridge running too often. The fridge is located out of direct sunlight, and i keep the temp at 66. Any tips or ways to fix this?
