Kitchenaid Refrigerator Not Cooling But Freezer Works. The thermistor is a sensor that monitors air temperature. The start relay helps to start the compressor, and thus cool the refrigerator.
But first, check the start relay or start capacitor. The thermistor is a sensor that monitors air temperature. From there, the keys on the touch pad become soft keys.
The freezer works fine, the fan blowing air from the freezer to the fridge appears to work fine, but when i check to see if cold air is getting into the fridge there is no air flowing, it appears, from the bottom freezer unless i open the bottom freezer drawer at least a crack.
You can test the start relay with a multimeter and replace it if necessary. Turn the blades of the condenser fan with your hand to know if the motor is faulty. If the refrigerator is not cold enough there might be something caught in the condenser fan motor blade, or the condenser fan motor might be defective. If they don’t turn freely, the fan motor is bad.
