Bosch Gas stove burner won't light
When your Bosch gas stove burner won't light, start with the burner cap, since a cap that is misaligned on the burner base can prevent the spark electrode from igniting the gas. Turn off the Bosch gas stove and let the cooktop cool, then reseat the cap correctly. If the cap is positioned properly, a weak or intermittent spark may point to the spark module. Check the spark electrode and spark wire before replacing the Bosch spark module. Next, confirm the range is receiving incoming power by testing the outlet with another device and checking the circuit breaker or fuse. If the other burners spark but one burner does not, the spark ignition switch may be defective. Some Bosch models require the spark ignition switch and harness assembly if the switch is not sold separately. A worn or defective spark electrode can also cause clicking without ignition. Inspect these parts carefully, and shut off the gas supply before servicing gas components. Enter your model number to find the exact replacement part for your Bosch gas stove and get the right fit for your repair.
01 - Burner cap not on correctly
If the burner cap is misaligned on the burner base the igniter may not spark properly, and the burner flame will be uneven. Confirm the appliance is turned off and the stovetop is cool to the touch, then readjust the burner cap, if necessary, so it is seated properly on the burner base.

02 - Bosch Range/Stove/Oven Spark Module
The spark modules provides power to each surface burner spark electrode. If the burner is produces a weak spark, or if the burner sparks intermittently, the spark module might be defective. Before replacing the spark module, first check the spark electrode and the spark wire. If the spark electrode and spark wire are not at fault, the spark module is likely defective. If the spark module is defective, replace it.

04 - Bosch Range/Stove/Oven Spark Ignition Switch
When the burner is turned on, the spark ignition switch sends voltage to the spark module to produce a spark. If the spark ignition switch is defective, it won't send voltage to the spark module, and the burner won't be able to produce a spark. If your range's burner isn't sparking, check to see if the other burners are sparking properly. If the other burners are sparking properly, the spark ignition switch is likely defective.

05 - Bosch Range/Stove/Oven Spark Ignition Switch and Harness
When the burner is turned on, the spark ignition switch sends voltage to the spark module to produce a spark. If the spark ignition switch is defective, it won't send voltage to the spark module, and the burner won't be able to produce a spark. If your range's burner isn't sparking, check to see if the other burners are sparking properly. If the other burners are sparking properly, the spark ignition switch is likely defective. If the spark ignition switch is not sold separately, you will have to purchase the switch and harness assembly.

06 - Bosch Range/Stove/Oven Spark Electrode
The spark electrode sends a spark to ignite the gas in the burner assembly. If the spark electrode is defective or worn out, it might not produce a spark, or the spark might be too weak to ignite the gas. As a result, the spark electrode will make a clicking sound when the burner is turned on, but the burner won't light. If the spark electrode is defective, replace it.
