Direct answer
A wrong result requires checking inputs, mode, calibration and output separately; a working control path can still be configured for the wrong state. 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
ReversibleWrite down the selected mode, input conditions and the exact unexpected output. 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. Use a known reference input or manufacturer test and compare the result. 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 setting, calibration or component proven by that comparison.
Verify and stop safely
ReversibleRepeat with the reference and a normal real-world case. 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.
