Whirlpool Top Burner Spark Igniter 74004053 — What It Fixes and How to Replace It

Understanding the Problem

What this part is and why it matters: The 74004053 (often sold as WP74004053) is the surface burner spark igniter/electrode used on many Whirlpool, KitchenAid and Maytag gas ranges. It produces the high-voltage spark at a specific point next to the burner ports so the gas lights. When it fails you’ll see clicking with no spark, intermittent ignition, or continuous sparking. Step-by-step diagnostic & repair instructions: 1) Safety first: shut off the oven/range power at the breaker and turn off the gas supply. Wait a few minutes for any residual voltage to discharge. 2) Confirm the symptom: remove the grate and burner cap. In a dim room, turn one burner to the LITE position and look for a visible spark at the electrode. If the burner clicks and you see spark, the igniter is producing a spark. If you hear clicking but no spark, the electrode or its wiring is suspect. 3) Visual inspection: look for cracked or broken ceramic on the electrode, carbon tracking (dark lines), melted tips, or corrosion at the connector. Any damage or heavy carbon deposit can short the spark or prevent it from forming. 4) Drying test: if the range was recently cleaned or there is moisture, dry the area thoroughly (hair dryer on low, fan or wait). Moisture often causes continuous clicking. 5) Continuity test (optional): with power off and the igniter disconnected from its harness, use a multimeter set to continuity/ohms and check for a closed circuit through the igniter wiring. An open/infinite reading usually means the electrode is broken and should be replaced. (Note: some electrodes are simple conductors so you should see continuity; others are more complex—if unsure, skip to replacement.) 6) Replace the igniter: remove grates, burner caps and burner head. Depending on model you may need to remove a few screws to lift the cooktop or simply pull the burner ring aside. Disconnect the igniter wire connector, remove the mounting screw or clip holding the electrode, replace with part 74004053, route and connect the wire exactly as removed, reassemble the burner head, cap and grate. 7) Test: restore power and gas. In a dim room, turn the burner to LITE and confirm a steady visible spark and that the burner lights reliably. If the new igniter sparks but the burner still won’t light, the problem may be the gas valve or gas supply. 8) If multiple burners produce no spark at all: suspect the spark module, fuse, or control board rather than the individual igniter. If only one burner fails, the igniter or its wiring is usually the culprit. Final safety note: Always cut power and gas before working on a range. If you smell gas strongly, ventilate, do not operate electrical switches, and contact a professional or gas utility immediately.

Common Symptoms

Burner clicks but won't light; intermittent ignition on one burner; continuous clicking; visible crack or carbon tracking on electrode; one burner dead while others work.

Common Causes

• Cracked, broken, or fouled igniter electrode (ceramic tip damaged or carbon-tracked)
• Damaged or corroded igniter wiring/connector preventing spark
• Moisture or food/residue causing shorting or continuous clicking (or faulty spark module if all burners fail)
