Most Frequent Causes for Range Burners Spark All The Time
| Cause 1 Spark Ignition Switch | Cause 2 Spark Ignition Switch and Harness | Cause 3 Spark Module |
| One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the spark ignition switch fails with the electrical contacts closed, the switch will send continuous voltage to the spark module. To determine if any of the spark ignition switches is defective, use a multimeter to test each of the switches for continuity. If a spark ignition switches shows continuity at all settings, replace it. | One of the spark ignition switches might be defective. The spark ignition switch sends voltage to the spark module. When the electrical contacts inside the switch close, power flows to the spark module. If the switch contacts are wet or stuck in a closed position, the switch will send continuous voltage to the spark module, no matter where the dial is set. Each of the switches can be tested individually to determine if they are shorted. If a spark ignition switch is shorted and is not wet, or if drying it out doesn’t solve the problem, replace the switch. | The spark module provides power to each surface burner spark electrode.
