Refrigerator runs constantly and is too cold; food freezing in fresh food section.

Safety first: Unplug the refrigerator before accessing sensors or control boards.

Steps to resolve:

• Check settings: Set the refrigerator to 37–40°F (3–4°C) and freezer to 0°F (-18°C). Avoid the coldest settings unless necessary.
• Relocate sensitive items: Keep produce and liquids away from direct airflow vents where temperatures are coldest.
• Inspect thermistor location: Ensure the refrigerator thermistor is not directly in the path of cold air or touching the evaporator cover.
• Power reset: Unplug for 5 minutes, then restore power to reset the control.

If the unit continues to run excessively and temperatures remain too low, the thermistor or control board may be defective and should be tested and replaced by a technician.
