Mickee S. for Model Number MBR2256KES 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
Answer 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. Read More... Answered by AppliancePartsPros.com | Thursday, November 7, 2013
