Troubleshooting Guide: Continuous Sparking of Cooktop Igniter

Reference: Appliance Fixer Gas Safety Check conducted on June 2023 in Boronia, VIC

It can be incredibly annoying when your cooktop igniter continuously sparks. Not only is the constant clicking sound irritating, but it can also be dangerous. When the igniter keeps sparking, gas can continuously flow out, creating a potential hazard in your kitchen. Here’s what you need to do to address this issue.

  • Step 1: Unplug the cooktop from the electrical outlet. The reason for this is that the oven ignition is electrically powered. By disconnecting it, you’ll stop the constant clicking of the igniter.
  • Step 2: Wait for 5 days. This will give ample time for any moisture to evaporate from the cooktop.
  • Step 3: In the meantime, the cooktop is still functional. You can use a lighter as an ignition source to continue using it.
  • Step 4: After waiting for 5 days, plug the cooktop back in. If moisture was the issue, it would have evaporated during this time, and the sparking issue should be resolved.
  • Step 5: If following the previous steps did not fix the issue and the cooktop’s igniter continues to spark, it’s important to call us for further assistance.

Explanation of Issues

Moisture in Igniter

Moisture can enter the cooktop’s igniter area due to various reasons such as spills during cooking, high humidity in the kitchen, or even cleaning with excessive water. 

When moisture accumulates in this area, it can interfere with the proper functioning of the igniter, leading to continuous sparking. 

This can be particularly problematic with gas cooktops because the continuous sparking can also result in a constant flow of gas, posing a safety risk.

If moisture is indeed the cause, waiting for it to evaporate as mentioned in the previous steps can often resolve the issue. However, if the problem persists even after drying out, it may indicate a faulty igniter that needs professional attention.

Faulty Igniter

A faulty igniter can be caused by several factors:

  • Age and Wear: Over time, the igniter components can wear out or degrade, leading to malfunction.
  • Contamination: If grease, food particles, or cleaning chemicals enter the igniter area, they can interfere with its operation.
  • Physical Damage: Accidental impacts or rough handling can damage the igniter, affecting its performance.
  • Electrical Issues: Wiring problems or electrical shorts can also lead to igniter malfunction.


If the issue persists despite drying out the cooktop and ensuring no moisture-related problems, it’s likely a faulty igniter. In such cases, you can either keep the cooktop unplugged and use a lighter for ignition temporarily, or it’s advisable to contact a professional for repair or replacement of the faulty igniter.
