- Screwdriver
- Towel
Parts Required

- Spark module (if all burners affected)
Diagnostic Steps
1
Test all burners. If none ignite, check the 120V breaker for the range — igniters are electrically powered.
Expected: Isolates whether one burner or all burners are affected.
2
Remove grate and burner cap. Inspect igniter ceramic for cracks, moisture, or food buildup.
Expected: Clean, dry ceramic igniter.
If fails: Clean and dry before retesting.
3
Clean igniter with dry toothbrush. Check burner cap ports with a paperclip to clear any blockage.
Expected: Ports are clear and igniter is clean.
4
Re-seat burner cap flat and centered. Restore power and test.
Expected: Burner ignites within 2-3 seconds.
If fails: Replace igniter switch if still no spark.

- Remove burner cap and clean igniter with dry toothbrush. Allow to air dry if wet.
- Clear clogged burner cap ports with a straightened paperclip.
- Re-seat burner cap flat and centered.
- Replace igniter switch or spark module if no spark after cleaning.
