Gas Burner Won't Light?
Troubleshooting Gas Range Ignition Problems
Understanding This Problem
When a gas range burner clicks but won't light, or won't click at all, cooking becomes difficult. Many ignition problems have simple causes like spilled food or moisture, while others require professional attention. Understanding the difference is key.
Common Causes (Most to Least Likely)
Wet or Dirty Igniter
Spilled food, grease, or moisture on the igniter can prevent proper spark. This is especially common after cleaning or spills.
Clogged Burner Ports
Food debris can clog the small holes in the burner cap where gas flows, preventing even ignition or any ignition.
Misaligned Burner Cap
If the burner cap is not seated correctly after cleaning, gas flow and ignition can be affected.
Faulty Spark Igniter
The igniter creates the spark that lights the gas. If it fails, you won't hear clicking or see a spark.
Faulty Spark Module
The spark module sends electricity to all igniters. If it fails, multiple burners may not spark.
Gas Supply Issue
A closed valve, empty propane tank, or supply line issue will prevent all burners from lighting.
Warning Signs to Watch For
- Strong gas smell (turn off gas and ventilate)
- Multiple burners affected simultaneously
- Clicking continues even when burner is turned off
- Weak or orange flame instead of strong blue flame
- Flame lifts off or is uneven around the burner
Things to Try First
Before calling for service, try these troubleshooting steps:
- 1Dry the igniter area if wet—leave burner caps off to air dry
- 2Clean burner caps and grates with warm soapy water
- 3Use a toothbrush or pin to clear clogged burner ports
- 4Ensure burner caps are properly seated and level
- 5Check that the gas shutoff valve is fully open
- 6Light manually with a match while troubleshooting (carefully)
