- 1
Allow components to dry
If moisture is suspected, allow burner caps, heads, and igniter area to dry completely. A hairdryer on low can accelerate this.
- 2
Clean burner caps and heads
Remove burner caps and heads. Wash in warm soapy water, scrub with soft brush, and dry completely before reinstalling.
- 3
Clear burner ports
Use a straight pin to clear each port hole in the burner head. Do not use toothpicks that can break.
- 4
Clean the igniter
Gently clean the igniter electrode with a soft toothbrush. Remove any buildup around the base.
- 5
Verify burner cap alignment
Ensure burner caps are seated flat and properly aligned. Crooked caps prevent proper ignition.

Check other burners
If one burner lights, compare its components to the problem burner. Look for differences.
