Gas Range Won't Light? Troubleshooting Igniter Problems

# Gas Range Igniter Troubleshooting When your gas range won't light, it's usually an igniter problem. Understanding how igniters work helps you diagnose issues and know when professional repair is needed. ## How Gas Igniters Work Modern gas ranges use electronic ignition: 1. You turn the burner knob 2. Gas valve opens 3. Igniter creates spark or heats up 4. Gas ignites 5. Flame sensor confirms ignition Two main types: - **Spark igniters:** Create visible spark (click-click sound) - **Hot surface igniters:** Glow orange before gas releases (mostly ovens) ## Cooktop Burner Problems ### Problem: Clicking but No Flame **Causes:** 1. Wet burner components 2. Food debris blocking ports 3. Misaligned burner cap 4. Weak spark (failing igniter) 5. Gas supply issue **Solutions:** 1. Dry all burner parts completely 2. Clean burner ports with a pin or brush 3. Ensure cap is seated properly 4. Igniter replacement (professional) 5. Check gas supply valve ### Problem: One Burner Won't Light, Others Work **Causes:** 1. Clogged burner ports 2. Failed individual igniter 3. Damaged igniter wire 4. Burner cap issue **Solutions:** 1. Deep clean the specific burner 2. Professional igniter replacement 3. Wire repair or replacement 4. Inspect and reseat cap ### Problem: All Burners Click Continuously **Causes:** 1. Moisture in igniter switches 2. Stuck igniter switch 3. Control module issue **Solutions:** 1. Let switches dry completely 2. May need switch replacement 3. Control module diagnosis ### Problem: No Clicking At All **Causes:** 1. No power to range 2. Failed igniter module 3. Disconnected wires **Solutions:** 1. Check electrical connection 2. Module replacement 3. Professional inspection ## Oven Igniter Problems ### Problem: Oven Won't Light **Symptoms:** - Gas smell without ignition - Long delay before ignition - No heating at all **Causes:** 1. Weak igniter (most common) 2. Failed igniter 3. Gas valve issue 4. Safety valve problem ### Testing Oven Igniters **Glow test (hot surface igniters):** - Turn on oven - Watch igniter through oven window or open door slightly - Igniter should glow bright orange within 60 seconds - Gas should ignite within 90 seconds **Weak glow = failing igniter** Igniters weaken over time. A dim glow means the igniter can't get hot enough to open the safety valve. ## Wolf Range Specifics Wolf ranges feature: - Dual-stacked burners with individual igniters - High-performance igniters rated for professional use - Spark ignition for all cooktop burners **Common Wolf igniter issues:** - Debris from high-heat cooking - Grease buildup affecting spark - Individual igniter failure ## Viking Range Specifics Viking ranges have: - Sealed burner design - Electronic ignition modules - Professional-grade components **Common Viking issues:** - Igniter electrode positioning - Control module failures - Electrode cracking from heat stress ## Safety Considerations **If you smell gas:** 1.
