Possible Causes
How to Fix / Troubleshooting
Safety: Disconnect power before opening the control panel.
What to try:
- Hard reset: Unplug the ice maker for at least 15 minutes to allow capacitors to discharge. Plug back in and attempt to start a cycle.
- Check power source: Plug the unit directly into a grounded wall outlet (no extension cords or power strips). Verify outlet voltage is stable with another appliance.
- Inspect control connections: Remove the top or front panel to access the control board and display PCB. Ensure all ribbon cables and connectors are fully seated and not corroded.
- Look for visible damage: Examine the control board for burnt components, bulging capacitors, or signs of moisture intrusion.
Next steps: If E7 remains after reseating connectors and power cycling, the main control board is likely defective. Replacement requires transferring all connectors correctly and should be done by a technician or an experienced DIYer following a service manual.
