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-dryer ignition and flame, first confirm valve open and observe ignition behavior externally during Timed Dry.
What this covers
- gas-dryer ignition and flame with this exact failure state
- Diagnosis across gas supply versus igniter, valve/coils, sensor and vent
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: ignite controlled flame only with airflow and safety conditions satisfied.
Isolate the component boundary
ReversibleConfirm valve open and observe ignition behavior externally during Timed Dry. Try the simplest normal cycle with a light or empty load, keeping the door/lid and power connection unchanged. Boundary to separate: gas supply versus igniter, valve/coils, sensor and vent.
Correct only the proven cause
ReversibleCorrect only external supply/airflow and use qualified gas service internally. 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. Leave and call the gas utility/emergency services for strong gas odor.
