Introduction

Use this guide to replace the fresh food thermistor on your GE side-by-side refrigerator.

The thermistor enables the refrigerator control to monitor air temperature inside the refrigerator.

If the fresh food thermistor fails, the refrigerator will not maintain a proper temperature in the fresh food compartment.

This guide was created using a GE model GSH25KGMB BB side-by-side refrigerator. Other GE side-by-side units should be similar.

Unplug your refrigerator before you begin your repair.
If you are testing or repairing the following items, you may also need to shut off and disconnect the water supply:
Condenser fan motor
Compressor motor and thermal overload device
Water supply valve assembly

Lift the front edge of the shelf to release it from the support bracket.
Lift the rear of the shelf slightly, while the front edge is lifted, and pull the shelf out toward the front of the compartment
Repeat for each shelf as needed.

Use a 1/4" nut driver to remove the two screws securing the damper cover to the left wall at the rear of the fresh food compartment.

Remove the damper cover by pulling it straight out from the wall of the fresh food compartment.
It may take some persistence as the cover is held in place by a bracket mounted to the top of the compartment.

If the thermistor is defective, either open circuit, short circuit, or out of specification for a temperature, cut the leads and splice in a new unit.
Make sure that the splices are made waterproof. Stagger the splices as well.
The two red marks in the photo show a suitable part of the wiring for splicing in the new thermistor.

Conclusion

To reassemble your device, follow these instructions in reverse order.
