How to Fix / Troubleshooting
Safety first: Unplug the freezer before working on accessory modules.

- Check connections: Access the accessory (often in the top or side of the freezer) and ensure its wiring harness is firmly connected.
- Reset accessory: For SmartDevice modules, remove the module, wait 1–2 minutes, then reinstall and reconnect power.
