A cycle that takes noticeably longer than normal usually reflects load size, water temperature/pressure, or a sensor extending the cycle, not a failing motor. 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
ReversibleTime the cycle against the manufacturer's stated duration for that exact setting and load size. 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. Run the same cycle with a smaller, standard test load and normal supply conditions. 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. Adjust the load size or cycle selection, or correct the supply condition — water pressure, temperature or airflow — causing the extension.
Verify and stop safely
ReversibleRepeat the same cycle and confirm the duration returns to the expected range. 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.
