All gas surface burners click continuously even when knobs are in the OFF position.

Safety first: Unplug the range or turn off power at the breaker. If you smell gas, shut off gas and ventilate.

Steps to check and correct:

• Dry out moisture: If the issue started after cleaning, remove burner knobs and allow the area to dry thoroughly. You can use a fan to speed drying.
• Inspect switches: Under each knob is a small switch. Check for broken housings or signs of liquid intrusion. Replace any damaged switches.
• Test individually: With power restored, turn each knob on and off to see if the clicking stops when a specific switch is disconnected (this is best done by a technician).
• Replace spark module: If all switches test good but clicking continues, the spark module may be defective and require replacement.

When to call a technician: Diagnosing which switch or module is at fault often requires live testing; professional service is recommended.
