How to Fix / Troubleshooting
Safety First: Unplug the freezer before testing switches or sensors.
- Step 1 – Confirm actual temperature: Use a thermometer to verify that temperature is stable around 0°F (-18°C).
- Step 2 – Check door switch: Wiggle the door while watching the interior light. If it flickers, replace the door switch.
- Step 3 – Inspect sensor wiring: Ensure thermistor harnesses are secure and not damaged.
- Step 4 – Reset alarm: Use the Alarm Reset button. If alarms persist without real temperature issues, the control board may be overly sensitive and require replacement.
