Gas-dryer ignition and flame keeps disconnecting or working intermittently

An appliance that fails partway through a cycle and sometimes completes normally usually points to a specific stage — fill, wash, spin, heat or dry — not total failure. This record isolates gas-dryer ignition and flame through gas supply versus igniter, valve/coils, sensor and vent.

An appliance that fails partway through a cycle and sometimes completes normally usually points to a specific stage — fill, wash, spin, heat or dry — not total 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

    1. Capture the exact failure state

      Reversible

      Note exactly which stage the cycle stops or errors at, and whether it's the same stage each time. Expected behavior: ignite controlled flame only with airflow and safety conditions satisfied.

    2. Isolate the component boundary

      Reversible

      Confirm valve open and observe ignition behavior externally during Timed Dry. Run the specific stage in isolation where the appliance allows it, and repeat with a different, similar-sized load. Boundary to separate: gas supply versus igniter, valve/coils, sensor and vent.

    3. Correct only the proven cause

      Reversible

      Correct only external supply/airflow and use qualified gas service internally. Correct the loading, supply or setting proven to affect that one stage, or arrange service for a component fault confirmed at that stage.

    4. Verify and stop safely

      Reversible

      Run two complete normal cycles in a row and confirm the same stage no longer fails. Leave and call the gas utility/emergency services for strong gas odor.
