  • Helps resolve symptoms like weak or uneven burners, weak ignition, or yellow/sooting flames when caused by a restricted orifice
  • Used on the oven top/burner assembly where a #38 sized jet is specified
  • Fits into the burner orifice holder and works with the existing regulator and valve
What's included: One orifice (natural gas, #38) Install notes:
  • Install only after shutting off the gas supply and following all safety procedures; check for leaks with a soapy water solution or approved leak detector

The Oven Burner Igniter is an OEM part for Bosch ranges. This part ignites the gas burner to provide the necessary heat for cooking. The igniter works by heating up and creating a spark that ignites the gas, ensuring efficient and reliable operation of the oven.

Causes of a bad igniter can include regular wear and tear, damage from repeated heating cycles, or issues with the electrical connections.  

Symptoms of a bad igniter include:

  • The oven not heating up
  • Difficulty igniting the burner
  • The burner not staying lit
  • Unusual clicking or sparking noises during ignition

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore models.

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
What's included: 1 glow igniter Install notes:
  • 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
