Safety first: Turn off all burner knobs. If you smell gas, turn off the gas supply and ventilate the area.

Steps:

Check power: Verify that the cooktop/range is plugged in and that the circuit breaker is on. Test the outlet with another appliance.
Manual lighting test: With caution, try lighting a burner with a long match or lighter. If it lights, the gas system is working and the issue is with ignition only.
Inspect power cord and terminal: Disconnect power and access the rear or bottom to check the power cord and terminal block for loose or burnt connections.
Check internal fuse: Some SMEG models have an internal fuse on the ignition circuit. Replace if blown with the same rating.
Replace ignition module: If power is present but there is no clicking on any burner, replace the ignition module.

Warning: Do not leave burners lit with a match as a permanent solution; repair the ignition system properly.
