Introduction
Use this guide to replace the freezer thermistor on your GE side-by-side refrigerator.
The thermistor enables the refrigerator control to monitor air temperature inside the freezer compartment.
If the freezer thermistor fails, the refrigerator will not maintain a proper temperature in the freezer compartment. It may also affect the fresh food compartment temperature.
This guide was created using a GE model GSH25KGMB BB side-by-side refrigerator. Other GE side-by-side units should be similar.
