Spark Electrode Not Working — Causes & Parts

Spark Electrode Not Working

This is the narrower, electrode-specific version of "burner not lighting": use this page if you can hear or see that the spark itself is the problem, rather than a clogged burner or a gas-supply issue. The key diagnostic question is whether just one burner fails to spark or whether all of them do, because that points at a completely different part.

A very common false alarm is a damp electrode right after cleaning the cooktop -- moisture on the electrode tip or spark module can prevent sparking for a few minutes with no part actually failed. Let everything dry fully and retest before assuming a part needs replacing.

Also note the opposite failure: a burner that keeps clicking continuously even after you release the knob, or when no burner is turned on at all. That points at the spark module or a stuck igniter switch rather than the electrode itself, and is worth mentioning if you call a technician, since it narrows the diagnosis differently than a burner that simply will not spark.

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. Spark module failure — if none of the burners click or spark at all, the module that drives every electrode is the most likely cause. Part type: Cooktop Spark Module (316135701).
2. Cracked or fouled individual electrode — if only one burner fails to spark while the others work fine, grease or food debris coating that one electrode tip is the more likely cause -- clean and fully dry it before replacing anything.
3. Electrode positioned too far from the burner cap — a bent bracket or misaligned cap widens the spark gap beyond what the module can jump. Part type: Range Surface Burner Cap, 9,500-BTU (Matte Black) (316261804).
4. Moisture on the electrode or module after cleaning — a very common false alarm right after cleaning the cooktop -- let it dry fully and retest before ordering parts.
5. Wiring or connector between the module and that electrode — checked last, once the module, the individual electrode, and moisture are all ruled out.

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:
