Gas cooktop with electronic ignition shows F0 on display (if equipped) and burners do not ignite automatically

Safety first: Turn off all gas burner knobs. If you smell gas, ventilate the room immediately and do not operate electrical switches. Close the gas shutoff valve and contact a professional.

User checks:

• Ensure burner caps and crowns are correctly seated.
• Dry the area around the ignition electrodes if you recently cleaned or spilled liquid.
• Try igniting with a match or lighter; if the burner lights manually, the gas supply is present and the issue is with ignition.

Technician checks:

• Disconnect power to the cooktop.
• Access the underside and inspect the spark generator module and wiring to each electrode.
• Check for cracked ceramic insulators on electrodes and replace if arcing to chassis.
• Test the ignition module for output when a knob is turned (requires live testing; only for trained personnel).
• Replace the spark generator or control board if no spark output is present.
