Possible Causes
Corrupted microcontroller on main PCB, Damaged PCB due to moisture or power surge, Loose display/control panel ribbon cable, Shorted low‑voltage circuit on PCB
How to Fix / Troubleshooting
Safety first: Disconnect the ice maker from mains power before opening the control housing.
- Power cycle: Unplug the unit for at least 15 minutes to discharge internal capacitors, then reconnect and test. Sometimes transient faults clear after a full reset.
- Inspect control panel connections: Remove the top or front cover to access the display and main PCB. Reseat any ribbon cables or plug‑in connectors between the display board and main control board.
- Check for moisture: Look for signs of condensation or water ingress around the control area. Dry gently with a hair dryer on low heat (do not overheat) and allow the unit to sit for several hours before retesting.
- Visual PCB inspection: Examine the main PCB for burnt components, cracked solder joints, or corrosion. If damage is visible, the board should be replaced with an original Clatronic control PCB.
- Surge protection: After replacement, consider using a surge‑protected outlet to prevent future PCB failures.
