How to Fix / Troubleshooting
Safety first: Turn all burner knobs to OFF. If you smell gas, open windows, do not use electrical switches, and close the gas shutoff valve. Call a professional if the smell persists.
User checks:
- Verify that the cooktop is plugged in and that the circuit breaker is on.
- Try another electrical outlet with a small appliance to confirm power.
- Check that burner caps and crowns are correctly positioned.
Technician checks:
- Remove the knobs and test the ignition switches for continuity when pressed.
- Access the underside and inspect the spark generator module and wiring to each electrode.
- Replace any damaged ignition wires or cracked electrodes.
- If no clicking is heard on any burner when a knob is turned, replace the spark generator module.
