Quick Checks
Check the Gas Supply
Make sure the gas supply valve behind the stove is fully open. A partially closed valve can restrict gas flow.
Surface Burner is Wet?
If you recently cleaned the cooktop, make sure the burner and igniter are completely dry. Moisture can prevent ignition.
Check Other Burners
Try lighting other burners. If none of them light, the problem is likely with the main gas supply to the stove, not an individual burner.
Listen for the Igniter
When you turn the burner knob, listen for a clicking sound from the igniter. No clicking indicates a potential igniter problem.
Common Causes
Clogged Burner Ports
DIYDebris, food particles, or grease can block the burner ports, preventing gas from flowing evenly and igniting. Clean the burner head with a wire brush or a small needle to clear any blockages.
Dirty or Weak Igniter
DIYThe igniter creates the spark that lights the gas. If it's dirty, weak, or cracked, it may not produce a strong enough spark. Clean the igniter with a dry cloth. If cleaning doesn't help, the igniter may need replacement.
Faulty Igniter Switch
Call ProThe igniter switch sends power to the igniter when you turn the burner knob. If the switch is faulty, it won't send power. A multimeter can test the switch for continuity. Replacement requires disassembly.
Moisture Buildup
DIYAfter cleaning, trapped moisture can prevent proper ignition. Allow ample drying time, or use a hairdryer on a low setting to ensure complete dryness. This is especially common in Orange County due to coastal humidity.
Gas Regulator Failure
Call ProThe gas regulator controls the gas pressure to the burners. If it fails, it can cause insufficient gas flow. This requires professional diagnosis and repair.
Faulty Spark Module
Call ProSome gas stoves use a spark module to generate the ignition spark. If the module is faulty, it can prevent the burners from lighting. This typically requires professional replacement.
When to Call a Professional
- You smell gas even after the burner is turned off.
- You're uncomfortable working with gas lines or electrical components.
- You suspect a gas leak.
- You've cleaned the burner and igniter, and the problem persists.
Safety Warning
Gas leaks are extremely dangerous. If you smell gas, immediately evacuate the area, do not use any electrical switches, and call your gas company or 911 from a safe location.
Estimated Repair Cost
