Direct answer
Intermittent behavior is diagnosed by the trigger—movement, heat, load, sleep, distance or time—not by repeating broad resets. 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
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleLog the trigger, duration, indicator state and whether physical movement or temperature changes it. 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. Hold every variable constant except one cable, location, load or host at a time. 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. Replace or reconfigure the one variable that reproduces the drop.
Verify and stop safely
ReversibleRun beyond the previous failure time and through sleep, movement or load once. Stop for breaker trips, hot plug, arcing, smoke or damaged cord.

Exact questions
Common follow-ups
What should I check first when electric-dryer heat circuit has this problem?+
Test Timed Dry, reset both breaker poles once and verify exterior airflow.
Why not factory-reset immediately?+
The useful boundary is cycle setting/airflow versus 240-volt supply, heater and temperature controls. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
stop for breaker trips, hot plug, arcing, smoke or damaged cord.
