Answer to continue safely

Is it safe to keep using?

Maybe. If the burner cannot be lit, do not attempt to use that burner until the ignition fault is resolved. Other burners on the cooktop may continue to be used safely. If you suspect a gas leak (smell of gas without the burner running), evacuate and contact your gas provider immediately.

Can I reset the code?

No. Gas ignition faults do not have a software reset. The fault is mechanical or electrical — cleaning the electrode and burner area resolves most cases. A failed electrode or module requires physical replacement.

When to stop immediately?

Stop if you notice: Smell of gas near the cooktop at any time, Clicking continues after releasing the ignition knob.

Symptoms You May Notice

Clicking without ignition

The ignition system clicks continuously when the knob is pressed but the burner does not light.

Intermittent ignition

The burner lights on some attempts but not others, even with the same technique.

One burner fails while others light normally

The fault is isolated to a single burner, confirming the issue is at that burner rather than the ignition module.

Possible Causes

1

Wet or contaminated igniter electrode

Spilled liquid or grease on the ceramic igniter electrode is shorting the spark to ground before it can jump to the burner.

DIY Possible
2

Burner cap misaligned or blocked

The burner cap is not seated correctly or food debris is blocking the flame ports, preventing gas from reaching the spark zone.

DIY Possible
3

Faulty igniter electrode or lead

The ceramic electrode has cracked or the high-voltage lead has broken, preventing a spark from being generated at that burner.

Requires Professional
4

Failed ignition module

The electronic ignition control module has failed and is not generating high voltage for the affected burner circuit.

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Dry the igniter area

    If the cooktop has been recently cleaned or a spill occurred, ensure the area around the igniter electrode is completely dry. Use a soft dry cloth and allow adequate drying time.

    A hair dryer on a low setting held 15 cm from the burner area for 30 seconds can accelerate drying of a wet electrode.

  2. 2

    Clean the burner and igniter area

    Remove the burner cap and crown. Clean around the igniter electrode with a dry toothbrush to remove food debris and grease. Replace the burner cap and ensure it seats flat.

    The burner cap must sit level and flush — even a slight tilt can prevent correct flame distribution and affect ignition.

  3. 3

    Check gas supply

    Confirm the gas supply valve is fully open and that other burners on the cooktop or other gas appliances in the home are working normally.

    If no gas appliance in the home is working, the issue is with the gas supply — contact your gas provider, not an appliance technician.

  4. 4

    Test the igniter visually

    In a darkened room, press the ignition knob and observe the electrode. A healthy spark appears as a bright blue flash at the electrode tip. No visible spark confirms an electrode or module fault.

    Observe from a safe distance — never place your face close to a gas burner during ignition testing.

When to Call a Professional

Contact a qualified technician if:

  • Igniter electrode replacement requires accessing connections beneath the cooktop
  • Ignition module replacement involves gas appliance wiring
  • Any suspected gas leak requires immediate gas company involvement, not DIY repair
