Possible Causes
Blocked ventilation, failed cooling fan, overheated control PCB, defective temperature sensor on control board
How to Fix / Troubleshooting
Safety first: Turn off power and allow the unit to cool completely before inspection.
- Ventilation and fan: Confirm that cabinet ventilation is adequate and that the internal fan runs when zones are active.
- Clean internals: Remove the cooktop and open the bottom cover. Clean dust from the control board and fan area.
- Sensor check: Locate any temperature sensors on the control PCB (small NTCs) and ensure they are properly soldered and not physically damaged.
- Board inspection: Look for heat discoloration, cracked solder joints, or warped PCB near power components.
- Replace components: If the fan is faulty, replace the cooling fan. If the board shows damage or E6 persists, replace the main control board.
Warning: Do not bypass temperature sensors; they are critical safety components.
