How to Troubleshoot Gas Range Ignition Spark Problems

Modern non-commercial gas ranges rely on an electronic ignition system to ignite each individual burner. The electronic ignition system consists of a spark control module, which is installed in the control panel housing of the range, as well as several igniters, one on each burner. If one igniter or several igniters are not functioning, there are several steps that can be taken to determine the source of the malfunction.

  1. 1

    Turn the stove burner to the "Lite" position and examine the spark created by the igniter. Turn on the other burners and compare the sparks created by the igniters. A properly functioning igniter creates three to five blue sparks per second. If one igniter underperforms the other igniters, or does not function at all, the igniter is bad.

  2. 2

    Listen for the frequency of the creation of the sparks. A properly functioning igniter steadily creates three to five sparks per second. If the igniters are creating sparks at a much slower rate, there may be reverse polarity at the power outlet. If there is no clicking sound or no sparks created by any igniter, the spark module must be replaced.

  3. 3

    Examine any non-functioning igniter to ensure there is no food stuck to the side of the igniter, preventing the module from sparking.

  4. 4

    Pull the range away from the wall, then unplug the power cord. Remove the rear panel of the range by removing the screws securing the panel in place. Inspect the spark module for disconnected wires, or for signs of damage.
