Problem; The refrigerator (top section) is not cooling, no air is coming out of the air duct, the fan is working properly as I covered the freezer vent (duct) located in the rear of the freezer compartment with tape and now cold air is blowing from the top vent like it should. I assume there is some type of valve or flapper that controls the cold air flow to the upper refrigerator area. Would it be a control or stuck valve(flapper) that is the problem. Everything else works fine, ,I clean the coils, compressor and fan area yearly with compressed air and a vacuum so its almost as clean as it was when new. Thanks so much for this fix it yourself help section. Mickee
The only vent that would be for the refrigerator compartment is in the refrigerator. It is the duct that the air blows out of at the top rear of the refrigerator section. There is a damper there and if the damper is not opening then the unit will not get cold air from the freezer. You will want to check the damper for operation but also pull the rear cover in the freezer and check to see if there is heavy frost building up on the coils. If so then it would be a defrost issue in which you will need to test the defrost thermostat and heater for continuity. If there is no continuity then replace the part. If there is continuity then the control board in the refrigerator section would need to be replaced.
My fridge is too cold. I set it at 38F and it runs at 33F, less in the lower portion, so my salad freezes. What could the problem be? How should I trouble shoot it?
Answer PP, Your first checks need to be to the interior and shelves. First remove the crisper bins ands check for debris and wrappers on the bottom of the refrigerator compartment, especially the rear corners, if there is something blocking the slots in the floor, this disrupts the air flow and causes over cooling. Check and make sure the bottom of the door gaskets are clean and they close and seal across the lower mullion flange. Check and make sure there are no articles hanging over the sides or front of the shelves, or against the back and side walls, this also disrupts the air flow and "traps" air at the bottom of the compartment. Check the top shelf, make sure theres no large or bulky article in the center of the shelf, this will redirect the air away from the control panel and thermistor, it will also force the air down the back wall and cause freezing in the crispers.
Where is the thermistor (#12002355) located? And how to I get to it to replace it?
Answer Hello Amelia,
There are two in this unit. The freezer thermistor is near the freezer ceiling just off to the right mounted in a small cover on the rear wall. The fresh food thermistor is mounted in the upper light assembly.
