Use this guide to test and replace the freezer thermistor in 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 freezer thermistor monitors the temperature inside the freezer compartment. It has a resistance that varies according to temperature, and the main control board monitors this value.
If the thermistor fails, the freezer temperatures will not be correct, and an Er FS error code may show on the display.
