I bought two thermometers and found my refrigerator was set near the coldest setting while the freezer was perfect. I raised the temperature to about 1/2 way between coldest and warmest safe temperatures by moving the thermostat a small amount each day until the refrigerator was safe, but warmer by a few degrees. I also removed the baffles in the freezer and made a copper wire to go into the drain. I also changed out two parts, but I believe the problem was the temperature settings and nothing else.
