Important Tips for Bosch Models

Bosch gas ovens use specific igniter parts (e.g., Bosch OEM igniter models) that should be matched to the model number; generic igniters may work but confirmation of compatibility is required.

Possible Causes

Faulty igniter or ignition element

How to Identify: Igniter does not glow or spark when oven is turned on; oven clicking without ignition; visible signs of damage to the igniter element.

Part: Gas oven igniter / hot surface igniter

DIY Solutions

Advanced 30-60 minutes

Tools Needed: multimeter, screwdrivers, replacement igniter part

Disconnect power and gas supply to the oven.
