Hello, I have a Kenmore 10659502990 side by side refrigerator that has me a little puzzled after troubleshooting it. The freezer works fine but the refrigerator side is cold but not as cold, it is about 45 degrees after I turn the knob to 9 (max coldest setting) on the refrigerator thermostat. I checked the door damper and it opens and closes fine, I checked the defroster thermostat and that has continuity when it is cold, the evaporator fan works fine, and the heater coils also checked with continuity. The evaporator has no frost build up on it, and it is not stuck in defrost. Also, all the air flow vents are free from obstruction. After troubleshooting, seems that the damper is closing prematurely around 45 degrees and opens at 50 degrees. Not sure what controls the damper, if I need to replace the refrigerator thermostat that it is faulty or if this fridge has a thermistor, or if its a control board that makes the damper open and close? Everything is working properly but the refrigerator just can not hold temperature between 32-40 degrees. Please advise, what part I need to buy and replace. Thank you

I have the same problem with my kitchenaid (KSSC48QMS02). The freezer is working but the refrigerator is not cooling. I have turned off the entire system to allow the freezer to defrost. I turned the system on after 24 hours hopping that the freezer defrosted. The freezer is cooling but the refrigerator is not.

Please let me know what other troubleshooting I should do before I purchase parts.

I apologize for the late response. Thank you for the Service and wiring sheet,, but I finally had some time to check the Freezer temperature, and it is indeed between 0 and 5 degrees, its is about 1 and 2 degrees F, seems a little high since service sheet says it needs to be 0 and -5 degree F. Not sure what this might mean? Or how accurate thermometer is. Does the refrigerator might need refrigerant?
I will do the baffle diagnostics next and see if it passes.

Hello, I ran the baffle diagnostics and the refrigerator passed the test, baffle opened and closed as they should per the instructions. I went ahead and ordered the Fresh Food thermostat and installed it. Unfortunately, I still have the original problem. Fresh food side of refrigerator is still above 42 degrees when I set the thermostat close to Max setting(8 out of 9), and can not get the temperature between 32-40 degrees F. If I set the thermostat to default (5) the temperature is about 46-48 degrees F. Seems that there is something fundamentally wrong with my fridge since the Freezer temperature wont go below 0 degrees and fresh food section wont go below 42 degrees F. Not sure what to do next? Please advice. Thank you.

I will try that next, I will set freezer side to max setting and see if it goes below zero. Right now the setting is at 6, one number above default setting of 5, the temperature hovers around 2-5 degrees F. The strange part is the freezer side, the evaporator fan is blowing but the baffle is closed as though it has reached the desired temperature. When the baffle is open, I feel the air coming out of the baffle but it doesn't feel very cold.
