Possible Causes
Corrupted firmware on control PCB, failed memory IC, power surge damage, incorrect replacement PCB not programmed for model
How to Fix / Troubleshooting
Safety first: Turn off power at the mains before removing any covers.
- Power cycle: Disconnect power for 15 minutes to allow capacitors to discharge. Restore power and see if the error clears.
- Check model label: Confirm the control PCB part number matches the exact New World model. Incorrect boards can trigger configuration errors.
- Factory reset (if documented): Some models allow a service reset via key combinations; refer to the service manual if available. Do not attempt undocumented procedures.
- Replace control PCB: If F12 persists, the main control board is likely faulty and must be replaced with a correctly programmed New World PCB. This is typically a technician-level repair.
