⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: THERMISTOR ALARM Difficulty: Moderate
Problem: Either the freezer or refrigerator thermistor circuit is open. The freezer or refrigerator indicator light shows and temperature indicators 4 through 7 turn on in sequence.
How to Fix THERMISTOR ALARM Error (Step-by-Step)
- Disconnect the refrigerator from its power source by unplugging it from the wall.
- Determine which compartment, the freezer or the refrigerator, is triggering the alarm based on the indicator lights.
- Find the thermistor inside the affected compartment. It is a small sensor, often shaped like a small capsule, located behind a plastic cover on an interior wall.
- Use a small screwdriver or putty knife to gently release the clips or screws holding the cover in place.
- Disconnect the wire connector from the old thermistor and confirm the error stays cleared during a full test cycle.
- Connect the new thermistor to the wire harness and snap the sensor into its designated mounting spot.
- Reinstall the plastic cover, restore power to the refrigerator, and monitor it to ensure the alarm code is cleared.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
