Mark for Model Number LG LFXS24623W Refrigerator temp works great but freezer won't get below 24 degrees. There is no frost build up, it seems maybe the freezer sensor is off. At 0 degrees it's 30, turn down to minus 6 and it cools to 24.
Answer Mark, the freezer thermistor 6500JB2002X can be tested directly at the main control to verify if it has failed. With the refrigerator unplugged, the main control can be accessed behind the access panel located above the compressor section. The connection for the freezer thermistor is going to be connection CON7 pin 15 to pin 16. Both wires are blue and white striped. At 5 degrees Fahrenheit, the thermistor should read 17K ohms. At -4 degrees, the resistance should read 23K ohms. Between 23 to 32 degrees, the resistance should read between 10 to 8 K ohms. If the resistance does not match the temperature in the freezer, then the thermistor has failed. If the resistance does match the temperature directly in the freezer, then the main control EBR79267107 has failed. Read More... Answered by AppliancePartsPros.com | Thursday, July 18, 2019
