Switch, spark assembly restores the ignition switch that creates the spark for gas burners, helping burners light reliably. Replacing this assembly can stop continuous clicking, intermittent sparking, or complete loss of ignition at the burner. What it does:

• Sends spark pulses to the burner electrodes so gas ignites when a control is activated.
• Replaces a failed ignition/spark switch to restore consistent sparking.
• Common repair for symptoms like burners that won't light, intermittent spark, or controls that click but won't ignite.
• Designed as a direct-fit replacement for the factory switch assembly when the part number matches.

• Disconnect electrical power and shut off the gas supply before starting any repair.
• Handle electrodes and ceramic insulators carefully to avoid damage; do not bend or crack the ceramics.
• Match and reconnect wiring to the original terminals; ensure connectors are fully seated before testing.
