Gas Burner Not Lighting — Causes & Parts

Burner Not Lighting

A gas burner that will not light fails in one of two distinct patterns, and telling them apart narrows the cause immediately: either you hear clicking with no flame (an ignition or gas-flow problem) or you hear nothing at all (an electrical or spark-module problem). Note which pattern you are seeing before checking parts.

Never attempt to light a burner manually with a match or lighter as a diagnostic step, and never test the spark module or igniter with gas flowing -- if gas is flowing but not igniting, shut off the burner knob and diagnose with gas off, or call a licensed technician if you smell gas at any point.

With the burner off and cool, lift off the cap and burner head and inspect the ports for debris or discoloration -- this costs nothing and rules out the single most common cause before you test or order anything electrical. Wipe the ports clean, reseat the head and cap exactly as they came off (misalignment here causes its own ignition problems), and retest before assuming a part has failed.

Safety first: ranges and ovens combine electricity, gas, and extreme heat.

  • Shut off power at the breaker before removing any panel, testing a switch, or touching internal wiring -- don't rely on the range's own power or oven control being off.
  • On a GAS range, shut off the gas supply at the shutoff valve before working near the burners, igniter, or gas valve. Never test an igniter, spark electrode, or gas valve with gas flowing to the appliance.
  • If you smell gas at any point, leave immediately and call your gas utility from outside the house -- do not flip switches, light anything, or try to troubleshoot the smell yourself.
  • The oven cavity, bake and broil elements, and stovetop burners stay dangerously hot long after use -- let the range cool completely before opening it up or reaching inside.
  • Gas line connections and gas valve work require a licensed technician. Do not attempt to disconnect, repair, or replace a gas line or gas valve yourself.

Most Likely Causes

Work through these from most to least common -- most range and oven repairs turn out to be one of the first two or three parts on this list, not the last.

  1. Clogged or misaligned burner ports — soot or food debris blocking the burner head produces an uneven, weak, or absent flame even when the spark and gas are both fine. Part type: Range Surface Burner Head (316212400), Range Surface Burner Head (316558300), or Range Surface Burner Head (WB16T10046).
  2. Spark module or electrode not sparking — no clicking sound at all, or a visible spark jumping at the wrong burner position instead of the one you turned on. Part type: Cooktop Spark Module (316135701).
  3. Burner cap seated incorrectly, misaligning the spark gap — Part type: Range Surface Burner Cap, 9,500-BTU (Matte Black) (316261804).
  4. Low or interrupted gas supply at the regulator — confirm the shutoff valve behind the range is fully open first. Part type: Range Pressure Regulator (316091706).
  5. Wiring or connector to that burner's igniter circuit — checked last, once the burner head, spark module, and gas supply all test normal.

How to Confirm Before You Buy a Part

Before ordering any replacement part, take a minute to confirm the fit -- it is the difference between a repair that works the first time and a part that does not match.

  1. Find the model/serial plate. On most ranges it is behind the storage drawer or kick panel at the bottom front, inside the oven door frame, or on the back panel of the unit. See how to find your model number for exact locations by appliance type.
  2. Read the full model number exactly as printed, including letters and dashes -- manufacturers often reuse near-identical model numbers across different production runs that take different parts.
  3. Verify the part fits that exact model using the model and part lookup tool before ordering, rather than assuming a part fits because it looks the same as the one you are replacing.

The full model number matters more than the brand and body style alone: one range body design is often sold under many model numbers over several years, with the exact igniter, element, switch, or control board changing partway through that run. Two ranges that look identical side by side can still take different parts if their model numbers differ, even by a single trailing letter or digit.

When to Call a Licensed Technician

Most of the parts above are within reach of a confident DIY repair using basic hand tools and a multimeter. Two situations are the exception. First, anything that requires opening a sealed gas valve, running a new gas line, or repairing a suspected gas leak is technician-only work -- these repairs need pressure testing and code-compliant fittings that are not a basic-tool job, and a mistake here is a safety hazard, not just a wasted part. Second, if you have already replaced the most likely part from the list above and the symptom persists, or a fault code keeps returning after a full power reset, a licensed technician with brand-specific diagnostic tools can usually isolate the remaining possibilities faster than continuing to swap parts by trial and error.

Check Your Exact Model

Part numbers above cover common range and oven platforms, but the only way to be certain a part fits your range is to look it up by model number with the model and part lookup tool. A few real range models with parts already indexed:
