# Range cooktop burners will not spark, or spark continuously

> Range cooktop burners will not spark, or spark continuously: symptoms, likely causes and how a technician diagnoses it. Very common AGA issue. Mon–Sun 8:00AM–8:00PM. Call or text 206-427-7323.

Very common issue — here is how we diagnose it, which parts are usually involved, and when to call a pro.

**Very common** · Starts with cleaning

## What you will notice

- No clicking when the knob is pushed in
- One burner will not spark
- Clicking that will not stop even with all knobs off
- Sparking but no ignition

## What is usually behind it

- Ignition electrode / burner ports blocked by debris, grease or spillage (most common)
- Moisture around the electrode after a spill or cleaning (very common (causes continuous clicking))
- Ignition switch jammed or damaged (common)
- Spark module / spark generator failed (common)
- Burner head incorrectly located after cleaning (common)
- No power to the range (check first)

## How a technician diagnoses it

1. Confirm power is on — the burners will not spark without it, even though gas is present.
2. For continuous clicking: turn everything off, dry and clean the ignition electrodes to remove grease and debris, and let the area dry fully.
3. Check the ignition switch is not jammed.
4. If cleaning does not resolve it, check the spark electrode and spark wire before condemning the module. If those are good, the spark module is likely defective.
5. Confirm burner heads and caps are correctly seated after any cleaning.
