Freezer too cold, items rock hard and brittle, ice crystals on packaging, temperature below -10°F (-23°C).

Safety first: Disconnect power before accessing sensors or control boards.

• Step 1 – Adjust setpoint: Raise the freezer temperature setting by a few degrees and wait 24 hours to see if conditions improve.
• Step 2 – Check sensor placement: Ensure the thermistor is properly clipped to the liner or evaporator cover and not touching the evaporator coil directly unless designed to.
• Step 3 – Reset control: Unplug for 5 minutes, then restore power and reprogram settings.
• Step 4 – Replace thermistor if needed: If the freezer continues to overcool, the thermistor may be misreading temperature and should be replaced.
