How to Fix / Troubleshooting
Safety first: Unplug the freezer before opening the control panel.
Step-by-step checks:
- 1. Power reset: Unplug for 5 minutes, then reconnect. Observe if the display returns to normal.
- 2. Access display panel: Remove screws securing the front/top control panel and gently pull it forward.
- 3. Check connectors: Ensure the ribbon cable or wiring harness between the display and main PCB is firmly seated.
- 4. Inspect for moisture: Look for condensation or water marks. Allow the panel to dry completely if wet.
- 5. Replace display PCB: If the display remains blank or flickers despite good connections, replace the display PCB with a Gram-compatible part.
When to call a technician: If you are not comfortable handling electronic boards or if the main PCB power supply is suspected, contact a technician.
