KitchenAid Stove Burner Not Lighting

Common Symptoms

• Burner clicks rapidly but gas does not ignite
• One specific burner won't light while others light normally
• All burners clicking continuously even when all knobs are off
• Burner lights only after many attempts — delayed ignition with a 'pop'
• Sparking visible but flame does not catch
• No spark at all from one or more burner electrodes

Most Likely Causes

1. 1

   Moisture on the Igniter Electrode (Most Common After Boilover)

   Liquid from a stovetop boilover can soak the ceramic igniter base and surrounding burner area. Water is conductive — it creates a short path for the ignition spark, causing rapid clicking without a proper spark arc to the burner head. The spark fires into the moisture instead of the burner gas port. The fix is almost always free: dry the burner area thoroughly and let the stove air-dry for 30–60 minutes before attempting to light again. You can speed this up with a hair dryer on low heat. This is the most common cause of the 'clicks but won't light' problem on any gas range.

2. 2

   Clogged Burner Ports

   The burner head has a ring of small gas exit ports around its circumference. Cooked-on food residue, grease, and cleaning product residue can block these ports, preventing gas from reaching the spark at the igniter tip. A partially clogged burner will light unreliably or only after several attempts. A fully clogged section can prevent ignition entirely on that side of the burner. The fix is cleaning: a needle, straightened paper clip, or stiff nylon brush works well. Never use a toothpick that can break off and cause a deeper blockage.

3. 3

   Burner Cap Misalignment

   KitchenAid gas range burner caps must be seated flush and level on the burner base. After cleaning or a boilover disturbance, burner caps are frequently replaced crooked, which prevents gas flow from aligning with the igniter electrode. A misaligned burner cap causes the 'clicks but won't light' symptom. Lift the burner cap and reseat it — it should sit flat with no wobble. On KSGB900E and KSGG700E models, the burner cap has a specific orientation key on some burners — look for the alignment notch.

4. 4

   Cracked or Contaminated Igniter Electrode W10156630

   The porcelain igniter electrode W10156630 can develop hairline cracks from thermal cycling, physical impact, or aggressive cleaning with abrasive scrubbers. A cracked ceramic body allows spark energy to short to ground through the crack rather than arcing to the burner. Grease or food residue on the electrode tip also prevents a clean spark arc. Inspect the electrode for visible cracks or discoloration. Clean grease with a dry brush or toothbrush — avoid soaking the electrode in water or using steel wool. A cracked electrode must be replaced.

5. 5

   Failed Spark Module W10340303

   The spark module W10340303 is the control board that generates the high-voltage ignition pulses for all burners simultaneously. When you turn any burner knob to the START position, the spark module fires all electrodes at once — this is why all burners click when you light one. If the spark module fails, some or all igniters will stop sparking entirely (no clicking). A completely dead electrode (no click, no spark) after confirming the electrode itself is undamaged points to the spark module. W10340303 fits KSGB900E, KSGG700E, and KFGD500E models ($35–$75).

6. 6

   Gas Valve or Supply Issue

   If the igniter sparks correctly but the burner still won't light (no gas igniting the spark), the gas supply to that burner has been interrupted. Check that the main gas shutoff valve behind the range is fully open. If the igniter sparks visibly and gas supply is confirmed on other burners but one specific burner still won't light, the individual gas valve orifice for that burner may be clogged or the valve may have failed. Gas valve repairs require a qualified technician.

Quick DIY Checks

1. 1Step 1 — Gas safety first: before any hands-on inspection or cleaning, turn the affected burner knob to OFF. Confirm no gas odor is present. If you smell gas, do not attempt any repair — leave the home, avoid using any electrical switches, and call your gas utility from outside. For all non-emergency inspections, it is best practice to close the gas supply shutoff valve (behind the range on the flex line) before removing any burner components. Restore gas supply after reassembly and test all connections with soapy water.
2. 2Step 2 — Dry out the burner area (boilover recovery): if the issue started after a boilover or after cleaning, moisture is the prime suspect. Remove the burner grate and burner cap. Inspect the igniter electrode and burner base area for visible moisture or food residue. Dry all surfaces with a clean towel. Use a hair dryer on low heat to drive remaining moisture from the ceramic igniter base and the burner port area. Allow 30–60 minutes of air drying with the stovetop uncovered. Reseat the burner cap and attempt to light — in most boilover cases, this resolves the problem completely.
3. 3Step 3 — Check and reseat the burner cap: lift the burner cap off the burner base. Inspect the underside for food debris clogging the inner gas passages. Clean with warm soapy water and a soft brush. Before reinstalling, look at the burner base to confirm it is clean and dry. Reseat the burner cap flat and level — press down gently on all sides to confirm no wobble. On KSGB900E and KSGG700E models with a keyed burner cap, align the locating notch before seating. Replace the burner grate and test.
