An appliance that will not run a cycle at all should be separated into power/door-safety interlocks, the selected cycle's own requirements and the specific component before assuming a major failure. 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
What it does not cover
Try in this order
0 of 4 completedCapture the exact failure state
ReversibleCheck whether the appliance powers on at all, whether the door or lid shows as fully closed and locked, and whether an error code displays. 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. Try the simplest normal cycle with a light or empty load, keeping the door/lid and power connection 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. Fully close and re-latch the door, clear the specific error code's documented cause, or restore power at the breaker.
Verify and stop safely
ReversibleRun one complete normal cycle and confirm it finishes without re-triggering the fault. 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.
