The Johnson Controls J9993DDW Ignitor Pilot is an ignition assembly used in compatible commercial gas heating and cooking equipment. It generates the spark required to ignite the pilot flame and works with the flame sensing system during burner startup. This assembly features a 1/4-inch CCT tube connection, left flame pattern, 35-inch spark lead, integrated ignitor, flame sensor, and protective boot for ignition applications. Suitable for both natural gas and LP gas systems, it functions as part of the burner ignition circuit. Replacing a faulty pilot assembly restores proper ignition sequence and burner operation.
