Freezer interior is too cold, excessive frost on food, and temperature is much lower than setpoint.

Safety: Unplug the freezer before accessing controls.

Steps:

• 1. Verify settings: Ensure the temperature is not set to the coldest or fast-freeze mode permanently. Adjust to a higher temperature and wait several hours.
• 2. Mechanical thermostat models: If your Amica freezer uses a dial thermostat, remove the control housing and inspect the thermostat. If the compressor never stops regardless of dial position, the thermostat contacts may be stuck. Replace with an "Amica Freezer Thermostat".
• 3. Electronic models: Check for error codes. If none, but the compressor runs constantly, the main control relay may be stuck. This usually requires replacing the main control board.
• 4. Sensor placement: Ensure the freezer temperature sensor is correctly located and not touching the evaporator coil directly, which can cause it to read too warm and overcool.

Note: Overfreezing wastes energy and can damage packaging and food quality.
