Joe for Model Number CTB1925GR Refrigerator and freezer were both warm. Cleaned out bottom back of dust, ordered and replaced the thermostat. Refrigerator and freezer are now cold, but the compressor constantly runs. The door that pops open to allow the cold air from the freezer to drop down into the refrigerator is always open (never closes). I checked resistance on the old thermostat after removing it (got 362k ohms). There is also ice build up on the copper tube that the thermostat is clipped onto. What else can I check to figure out the problem?
Answer Joe, The first thing you have to look at is whether the refrigerator is getting too cold. If the refrigerator is getting too cold then there should be an adjustment screw on the thermostat that you can try to adjust it a little at a time. If the unit is not getting too cold then the unit is working as it should be. This unit does not have a door that opens and closes between the refrigerator and freezer. This is just a duct that allows the cold air to flow. Read More... Answered by AppliancePartsPros.com | Monday, October 7, 2024
