An appliance problem starting right after a house move, a new detergent or additive, or a water/gas/power supply change should be checked against that specific change first. For gas surface-burner ignition, first after cooling, clean/dry approved parts and seat the cap before one test.
What this covers
- gas surface-burner ignition with this exact failure state
- Diagnosis across wet/dirty cap and ports versus electrode, gas supply and switch

0 of 4 completedCapture the exact failure state
ReversibleNote exactly what changed — installation, supply type or product used — and confirm it worked immediately before. Expected behavior: spark and light promptly with a correctly seated clean burner.
Isolate the component boundary
ReversibleAfter cooling, clean/dry approved parts and seat the cap before one test. Test with the previous product or a factory-recommended one, or verify the new supply connection matches the appliance's requirements. Boundary to separate: wet/dirty cap and ports versus electrode, gas supply and switch.
Correct only the proven cause
ReversibleCorrect cap/port condition or use qualified gas service. Correct the installation, switch back to a compatible product, or arrange service for a supply mismatch that cannot be user-corrected.
Verify and stop safely
ReversibleRun one complete normal cycle under the new conditions and confirm normal results. For a strong gas odor, do not operate switches — leave the building and call the gas utility or 911 from outside; turn off the gas and ventilate for repeated clicking without flame.
