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