Unplug and Remove Old Thermistor: Disconnect power and carefully remove the old thermistor from its mounting
Before beginning the process of replacing the thermistor on your Whirlpool refrigerator, it is crucial to ensure your safety and the proper functioning of the appliance. Start by disconnecting the power supply to the refrigerator. This can typically be done by unplugging the power cord from the wall outlet or, if necessary, turning off the circuit breaker that supplies power to the refrigerator. Once the power is disconnected, you can proceed to remove the old thermistor.
Carefully locate the thermistor, which is usually mounted inside the refrigerator compartment. It may be attached to the back wall or another internal surface. Gently detach the mounting bracket or clip that holds the thermistor in place. Be cautious not to damage any surrounding components or wiring during this process.
After removing the mounting bracket, carefully pull the old thermistor away from its housing. Take note of how it is positioned and connected, as this will be important when installing the new thermistor. Ensure that you do not touch any electrical contacts or components with your bare hands, as this could result in electrical shock or damage to the refrigerator.
Once the old thermistor is removed, inspect it for any signs of damage or wear. If the thermistor appears to be in good condition, it may be possible to reuse it. However, if it is damaged or malfunctioning, it is recommended to replace it with a new one.
When handling the new thermistor, be sure to follow the manufacturer's instructions for installation. Align the new thermistor with the mounting bracket and carefully insert it into the housing. Secure the thermistor in place by reattaching the mounting bracket or clip. Make sure that all electrical connections are properly aligned and secured.
After installing the new thermistor, reconnect the power supply to the refrigerator. Turn the appliance on and allow it to run for a few hours to ensure that the new thermistor is functioning correctly. Monitor the temperature inside the refrigerator to make sure it is maintaining the desired level. If you encounter any issues or the temperature does not stabilize, you may need to adjust the thermistor or consult a professional for further assistance.
