Most Frequent Causes for Stove burner won't light

Cause 1Spark 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.

Cause 2Spark 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.

Cause 3Spark 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.
