Refrigerator is cold and the freezer is cold but not freezing?
Answer Hello Brian,
This can be either a lack of air circulation inside or out of the unit or there could be a sealed system issue.
I cant find the defrost heater in the diagrams, the fridge doesn't have one?
Answer Hello Jules. You need to order 5421JJ1001A for the heater. It is part of the evaporator assembly.
For the defrost thermostat, there are 2 orange wires (which I assume is the defrost thermistor) and a red and brown wires (which is a fuse of sorts). When I connect an multi-meter to the 2 orange wires (the thermistor), I would've expected the Resistance to DECREASE as the temperature INCEASED, however, in my case the opposite it true. How is this possible?
Answer Hi John. The defrost thermistor (sensor)part # part # 6615JB2005C has a reading of 30 ohms resistence at O°F. At 77° it will have approx. 5.8k ohms resistence. Basically this is the way these types of thermisters are classified. They are positive temperature type. You really check the voltage output of the main contol board to see if you are getting .5-4.5 vdc output at the Point "c" pin 61 AIN1 connection. Let us know your exact model # to cross reference the parts. Thank You.
