Customer Questions and Answers for Glow Igniter (Oven) by Bosch

This glow igniter heats electrically to light the appliance's gas burner. A weak or failed igniter can stop ignition or cause very long preheat times; replacing it restores reliable burner lighting and proper heating performance.

• Heats to a bright glow to ignite the gas burner
• Common fix for oven not heating or burner not lighting
• Often resolves long preheat times or intermittent ignition
• If the igniter doesn't glow—or glows but no flame appears—it may be weak or failed

• Disconnect power and shut off gas before servicing; allow the unit to cool completely
• Handle the ceramic element carefully; avoid touching the igniter surface and do not flex, drop, or strike it
• Transfer any reusable mounting hardware and wiring/connectors from the old part as needed
• Verify secure connections and proper positioning near the burner before restoring power and gas
