Requires ProfessionalSafe Checks You Can Do
-
1
Power cycle the cooktop
Turn off the circuit breaker for 5 minutes, then restore power.
A temporary electronic fault may clear with a complete power cycle.
-
2
Test each zone individually
After reset, turn on each cooking zone one at a time to identify if the issue is with one zone or all.
A single faulty zone points to the power module for that zone. All zones failing points to the main board.
When to Call a Professional
Contact a qualified technician if:
- Power module shows burned components
- Control board output voltages are incorrect
- Internal wiring shows heat damage
