Gas stove burners spark all the time: Common Causes & How to Fix

Repair Instructions:

One of the parts called spark ignition switches could be broken. This switch sends power to the spark module. When the electrical contacts in the switch close, power goes to the spark module. If the switch breaks while the contacts are closed, it will keep sending power to the spark module. To see if any of the switches are broken, you can use a tool called a multimeter to test each switch's continuity, which is the flow of electricity. If a switch shows continuity at all settings, it should be replaced.

How to Replace Range/Stove/Oven Spark Ignition Switch

1. Shut off power to the range at the main circuit breaker for safety.

2. Remove any control knobs, bezels, or panels covering the front surface area.

3. Locate the ignition switch mounted under the control knob cluster or gas valve.

4. Disconnect the wire harness by pressing locking tabs and pulling the connector.

5. Remove mounting screws or retaining clips holding the switch in position.

6. Remove the old ignition switch by gently wriggling it free from the mounting portal.

7. Insert the replacement switch at the same mounting point.

8. Reconnect the wire harness firmly until fully locked in place.

9. Secure with original screws or clips and tighten fully.

10. Replace any removed control equipment and test appliance ignition functions.

Repair Instructions:

One of the spark ignition switches could be broken. This switch sends power to the spark module. When the electrical parts inside the switch close, power goes to the spark module. If these parts are wet or stuck closed, the switch will keep sending power to the spark module, no matter where the dial is set. You can test each switch one by one to see if they're shorted, which means the electricity isn't flowing right. If a switch is shorted and it's not wet, or if drying it doesn't fix the problem, you should replace the switch.

Some burners have a special circuit that can sense the burner flame through the spark electrode circuit. If the burner has a good flame but the igniter keeps sparking, the orifice holder, which helps light the burner, might not be damaged and not grounding right. Check the holder to see if it's not lined up properly, and if it's not, you should replace it with a new one if needed.

Repair Instructions:

The stove's spark module sends pulses to each spark electrode to make a spark and light the gas. If the module can sense the flame, it'll automatically stop sending pulses when the burner lights up. If the electrode is broken, the module won't be able to sense the flame and the electrode will keep sparking after the flame is lit. Look at the electrode to see if it's visibly damaged or dirty, and if it is, it should be replaced.

Repair Instructions:

The spark switches, which are located under the burner knobs, need to be dry to work right. If water spills over or gets on the spark switches, they might short out, which can cause the burners to spark even when the switch is off. If this happens, unplug the stove and let it dry for a day.

Repair Instructions:

On some stove models, the spark module will stop the spark by itself when the burner lights up. If the burner cap isn't on right, the gas or flame might not reach the igniter, causing it to keep sparking. Make sure the burner cap is on correctly.
