A cycle that takes noticeably longer than normal usually reflects load size, water temperature/pressure, or a sensor extending the cycle, not a failing motor. 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
ReversibleTime the cycle against the manufacturer's stated duration for that exact setting and load size. 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 same cycle with a smaller, standard test load and normal supply conditions. 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. Adjust the load size or cycle selection, or correct the supply condition — water pressure, temperature or airflow — causing the extension.
Verify and stop safely
ReversibleRepeat the same cycle and confirm the duration returns to the expected range. Stop for breaker trips, hot plug, arcing, smoke or damaged cord.
