Dryer Thermal Cut-Off Kit
This kit contains both the thermal cut-off and the high-limit thermostat. The thermal fuse acts as a sacrificial safety link that permanently opens the circuit when the heater housing exceeds safe temperatures, usually due to airflow restrictions. Replacing the pair ensures that both the primary safety and the secondary limit are operating at factory specifications.

Dryer Heating Element
The heating element often fails when the coiled nickel-chromium wire fatigues, sags, and makes contact with the grounded heater housing. This creates a short-to-ground scenario that can cause localized overheating or 'runaway' heating, which triggers the thermal fuse. Replacing the element restores the integrity of the resistance-heating circuit.

Dryer Thermistor
The thermistor is a Negative Temperature Coefficient (NTC) resistor that sends temperature feedback to the control board. If its resistance drifts out of calibration (measured at ~12k ohms at room temperature), the control board may fail to cycle the heater off correctly, leading to the high-limit temperatures that blow the thermal fuse.
