Bosch Oven Burner Problems (Gas Ovens)
Burner cap not on correctly
Make sure the cap is properly aligned on the burner head. If the cap is misaligned the igniter may not spark properly, and the burner flame will be uneven.
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.
Incoming Power Problem
The electrical outlet may not be getting power. To determine if the outlet is getting power, try plugging something else into the outlet. If the outlet is not getting power, check the home circuit breakers or fuses.
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.
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.
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.
Bosch Range/Stove/Oven Surface Burner Valve
A stove burner that won’t light could be caused by a faulty surface burner valve. If you don’t hear the gas beginning to flow when you turn on the valve, the valve is likely defective and will need to be replaced.
Bosch Range/Stove/Oven Surface Burner Base
A stove burner that won’t light could be caused by a misaligned or corroded surface burner base. The base holds the orifice holder and electrode in place to allow ignition. Inspect the base for any damage or corrosion and replace the component if necessary.
Bosch Range/Stove/Oven Surface Burner Orifice Holder
A stove burner that won’t light could be caused by a bent or damaged surface burner orifice holder not allowing the gas to be ignited by the electrode. Inspect the holder to see if it’s misaligned and replace with a new one as required.
