How do I replace the temperature sensor on my LG refrigerator?
Keeping this in consideration, what causes a thermistor to go bad?
Usually, thermistor failure is caused by an open circuit due to mechanical separation between the resistor element and lead material. This can happen as a result of improper handling, thermal mismatch, or heat damage. Another common reason thermistors fail is simply aging.
In this regard, why is my LG fridge not cooling?
Check the condenser coils to determine if they are dirty—if the condenser coils are dirty, clean them. The condenser fan motor draws air though the condenser coils and over the compressor. If the condenser fan motor is not working properly, the refrigerator won't cool properly.
In refrigerators, the thermistor is a key part of the system that allows the refrigerator to stay within a short range of temperatures and turn on its cooling cycle when the temperature starts to rise. Problems with the thermistor will keep the refrigerator from operating correctly.
