Title	How to Test the Defrost Thermistor on your LG Refrigerator
Introduction	Use this guide to test the defrost thermistor on your LG refrigerator. ***This guide will work for most LG refrigerators.*** This guide is written with an LG model LFX25973 refrigerator. If you have a different model, you may encounter some minor disassembly differences, but the overall repair process will be the same. The defrost thermistor monitors the temperature of the defrost process and signals the control board when the heat needs to be shut down. If the defrost thermistor fails, the refrigerator will have trouble defrosting. Also a couple of error codes could be triggered. These will be displayed on the temperature displays. They may include the ***''dH''*** error if the unit isn't defrosting properly, and the ***''dS''*** error if the sensor is malfunctioning (Either short circuit or open circuit). Replacing the defrost sensor involves splicing wires in the freezer compartment. You can check to see if the connector is not plugged in properly when you check the sensor.
