The spark module provides power to each surface burner spark electrode. A common burner spark problem that occurs when the spark module fails is when there is a very weak spark, or the spark happens intermittently rather than the steady, continuous spark it should have. If the burner spark problem you're experiencing is that one of the spark electrodes is not sparking and the others are this could be due to a problem with the module although it is more likely to be a problem with the individual spark electrode.

If there isn't any spark when the burner is turned on, but there is a spark when one of the other burners is used then the spark ignition switch is probably defective. This is a common burner spark problem. Mounted on each burner control valve is a small switch, as the knob is rotated to the "Lite" position electrical contacts in the switch are pressed together and provide power to the spark module. If the spark ignition switch is defective no power is sent to the module and there is no spark. This burner spark problem is easily repaired by replacing the spark ignition switch for that burner.

If there is a clicking sound when the burner knob is turned on, but the burner being turned on doesn't light, the burner spark problem might be caused by a bad spark electrode. The electrode is a small device that sits right next to the burner. It functions like a spark plug. As power is applied to it a spark jumps from the spark electrode to the burner, igniting the gas. If the electrode is broken or worn out the spark may not occur or may jump to a different metal surface. This burner spark problem is easy to correct by replacing the spark electrode.
