An appliance problem starting right after a house move, a new detergent or additive, or a water/gas/power supply change should be checked against that specific change first. 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

0 of 4 completedCapture the exact failure state
ReversibleNote exactly what changed — installation, supply type or product used — and confirm it worked immediately before. 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. Test with the previous product or a factory-recommended one, or verify the new supply connection matches the appliance's requirements. 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 installation, switch back to a compatible product, or arrange service for a supply mismatch that cannot be user-corrected.
Verify and stop safely
ReversibleRun one complete normal cycle under the new conditions and confirm normal results. Leave and call the gas utility/emergency services for strong gas odor.
