Direct answer
A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. 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
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleWrite down the selected mode, input conditions and the exact unexpected output. 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. Use a known reference input or manufacturer test and compare the result. 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. Correct the setting, calibration or component proven by that comparison.
Verify and stop safely
ReversibleRepeat with the reference and a normal real-world case. Leave and call the gas utility/emergency services for strong gas odor.

Exact questions
Common follow-ups
What should I check first when gas-dryer ignition and flame has this problem?+
Confirm valve open and observe ignition behavior externally during Timed Dry.
Why not factory-reset immediately?+
The useful boundary is gas supply versus igniter, valve/coils, sensor and vent. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
leave and call the gas utility/emergency services for strong gas odor.
