How to Fix / Troubleshooting
Burn safety: Always treat zones with 'H' as potentially hot, even if you suspect a fault.
- Allow extended cooling: Give the hob several hours to cool and see if the 'H' indicators clear.
- Power reset: Turn off at the breaker for 10 minutes, then restore power.
- If 'H' remains permanently: The residual heat sensor or its circuit on the control board may be faulty. A technician should test and replace the sensor or PCB.
