How to Fix / Troubleshooting
Safety first: Unplug the cooler before removing the control panel or display assembly.
Steps to check and fix:
- 1. Power reset: Disconnect power for 5–10 minutes, then reconnect and test the buttons again.
- 2. Clean control surface: Wipe the touch panel with a soft, dry cloth. Do not use excessive water or cleaners that can seep behind the panel.
- 3. Inspect ribbon cable: Remove the control panel and check the ribbon or harness connecting the touch board to the main PCB. Reseat the connectors.
- 4. Replace touch panel: If certain keys never respond, replace the user interface/touch PCB with a Vestfrost-compatible part.
- 5. PCB replacement: If a new touch panel does not resolve the issue, the main control PCB may be faulty.
