Gas Stove Ignition Troubleshooting: Electrode, Igniter & Wiring Guide

Ignition failure is the single most common service call on a gas stove, and it almost always traces back to a small, replaceable part. For parts distributors, that means a steady stream of demand — if you can help your customers diagnose the fault correctly. Here is a practical troubleshooting guide you can share with every repair shop you serve.

The Three Ignition Components

Most gas stove ignition systems have three replaceable parts. The spark electrode sits near the burner and produces the spark. The igniter (or spark module) generates the high-voltage pulse. And the wiring and connections carry that pulse to each electrode. Any of the three can fail, and each needs a different fix.

Step-by-Step Diagnosis

• No spark at all — first check power and the igniter module, then the wiring.
• Weak or intermittent spark — usually a cracked or misaligned electrode, or a dirty ceramic insulator.
• Sparks but no flame — the gas path or nozzle is the likely culprit, not the ignition itself.
• One burner fails while others work — a single electrode or its wiring is at fault.

The Part Most People Miss

The ceramic insulator around the spark electrode cracks over time from repeated heating and cooling. A hairline crack lets the spark leak to ground instead of jumping to the burner — so the stove stops lighting even though nothing looks broken. Stocking replacement electrodes with durable ceramic insulation is a reliable, high-turn line for any parts business.
