Possible Causes

How to Fix / Troubleshooting
Safety: Unplug the freezer before accessing the control area.
Steps:
- Check cooling: Confirm that the compressor and fans are operating and the interior is cold. This indicates the main control may still be functioning.
- Access display: Remove the control fascia to expose the display board and connectors.
- Inspect connectors: Reseat the display harness and look for corrosion or damage.
- Visual inspection: Check the display PCB for burnt components or cracked solder joints. Replace the display module if damaged.
- Main board check: If the display is good but not receiving power, the main board’s low-voltage supply may have failed and require replacement.
Note: Label connectors before removal to ensure correct reassembly.
