Dryer Thermal Fuse
This is a non-resettable safety device that opens the electrical circuit to the heating element when internal temperatures exceed safe limits. When it blows, the dryer continues to tumble but produces no heat, leading the control board to blink the cooling light as it fails to detect a temperature increase. This is almost always caused by restricted airflow in the house exhaust ducting.

Heating Element Assembly
The heating element consists of a resistive NiCr coil that can fracture over time due to thermal expansion and contraction. A broken coil creates an open circuit, preventing heat generation and causing the control logic to bypass the drying phase and stay in a cooling or error state. Forensic evidence shows this typically occurs at the support insulators where mechanical stress is highest.

Dryer Thermistor
The thermistor is a Negative Temperature Coefficient (NTC) resistor that provides feedback to the main PCB. If the thermistor's resistance is out of range or fails to show change during the initial heat cycle, the dryer's firmware may terminate the heating phase immediately and trigger the cooling light to protect the load and the appliance from an uncontrolled thermal event.
