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 electric-dryer heat circuit, first test Timed Dry, reset both breaker poles once and verify exterior airflow.
What this covers
- electric-dryer heat circuit with this exact failure state
- Diagnosis across cycle setting/airflow versus 240-volt supply, heater and temperature controls

0 of 4 completedCapture the exact failure state
ReversibleNote exactly which stage the cycle stops or errors at, and whether it's the same stage each time. Expected behavior: receive both supply legs and cycle heat through protected elements.
Isolate the component boundary
ReversibleTest Timed Dry, reset both breaker poles once and verify exterior airflow. Run the specific stage in isolation where the appliance allows it, and repeat with a different, similar-sized load. Boundary to separate: cycle setting/airflow versus 240-volt supply, heater and temperature controls.
Correct only the proven cause
ReversibleCorrect household power/vent or service internal heater/controls. Correct the loading, supply or setting proven to affect that one stage, or arrange service for a component fault confirmed at that stage.
Verify and stop safely
ReversibleRun two complete normal cycles in a row and confirm the same stage no longer fails. Stop for breaker trips, hot plug, arcing, smoke or damaged cord.
