An appliance problem limited to one cycle, load, zone or operating condition should be separated from a component that fails every time. 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
ReversibleName the failing cycle, load, zone or operating condition and one safe condition that still works. 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. Change only the cycle, load, temperature, zone or installation condition while keeping the appliance setup unchanged. 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 isolated selection, loading, installation or operating condition.
Verify and stop safely
ReversibleRepeat the safe controlled cycle and compare the known-working condition. 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.
