This ignition device generates the high-voltage spark that lights gas burners so your cooktop or range ignites reliably. Replace a failing module to stop repeated clicking and restore consistent ignition. What it does:

• Produces spark pulses for gas burners and oven ignition.
• Stops continuous clicking when the burner won't light.
• Fixes intermittent ignition or no-spark symptoms at the burner.
• Helps prevent prolonged gas flow when ignition fails.

• Turn off electrical power and shut off the gas supply before beginning any service.
• Handle the module and wiring harness carefully.
• Avoid wetting the module or direct contact with high-voltage terminals; use basic hand tools and follow factory service instructions.
• After installation, test operation and check for proper ignition; if you smell gas or ignition still fails, stop.
