Gas Range Burner Won't Light: Causes and How to Fix It
Most gas burners that will not light are blocked or wet, not broken. Lift off the cap and head, clear each port with a straightened paperclip, wash and fully dry the parts, and reseat the cap flat and centered. Clicking with no flame after that points to the igniter, spark module, or gas supply. If you smell gas at any point, leave the home and call your gas utility first. Call (888) 822-7754 if it comes back.
When your gas burner won't light, the fix is often simpler than you'd expect, a clogged port or a damp burner cap. Other times the igniter or spark module has failed and needs a pro. This guide walks through why your gas stove is not lighting, the checks you can safely do yourself, and when to call a certified Express Xpert technician.
What the Burner Is Telling You
Match what you see and hear to a row below. Two of these you can clear yourself in under fifteen minutes, and the rest tell you exactly what to ask a technician to test.
| What you notice | What it means | What to do |
|---|---|---|
| Clicking, but no flame | The spark works but gas is not reaching it. | Dry and reseat the burner cap flat and centered, clear the ports, and confirm the shutoff valve is fully open. |
| One burner dead, the others work | A localized fault at that burner. | Clean that burner's ports and cap first. If it still will not light, its igniter or spark switch is the suspect. |
| Weak or orange-yellow spark | The igniter is failing. | Have a technician replace the igniter. A healthy spark is bright white-blue. |
| All burners clicking at once, or slow clicking | The spark module is weakening. | Book a technician to test the module and its wiring. This is high-voltage ignition work. |
| Gas smell at any point | A possible leak. | Leave the home and call your gas utility before anything else. |
Most Common Causes
When to Call a Pro
Call a professional if the burner still won't light after cleaning the ports, drying and reseating the cap, and confirming gas is on, or if you smell gas at any point (leave and call your utility first). Clicking with no spark, all burners clicking, or a cracked igniter point to ignition components that need a certified, insured technician.
