For LG Defrost Thermostat (Part Number: AP4457170)

Answer or Comment

View all Questions

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?

John for Model Number AP4457170

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.
