An appliance problem limited to one cycle, load, zone or operating condition should be separated from a component that fails every time. 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
ReversibleName the failing cycle, load, zone or operating condition and one safe condition that still works. 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. Change only the cycle, load, temperature, zone or installation condition while keeping the appliance setup unchanged. 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 isolated selection, loading, installation or operating condition.
Verify and stop safely
ReversibleRepeat the safe controlled cycle and compare the known-working condition. Stop for breaker trips, hot plug, arcing, smoke or damaged cord.
