Causes of a faulty temperature sensor can include wear and tear over time, damage due to electrical issues or exposure to extreme temperatures, or sensor calibration issues. These factors can result in temperature inconsistencies, inaccurate readings, or improper cooling performance of the refrigerator.

Symptoms of a bad temperature sensor may include:

• Incorrect temperature readings on the control panel
