Whirlpool WP3977767 High-Limit Thermostat for Dryer

The Whirlpool WP3977767 Dryer High-Limit Thermostat is for regulating the temperature within the dryer to prevent overheating. It monitors the internal heat levels and identifies any significant increases in temperature. When the temperature exceed a predetermined limit, it interrupts the electrical supply to the heating element, shutting it down. This interruption allows the dryer to cool down to a safe temperature before the thermostat resets and power is restored. By managing heat levels, it helps protect internal components from damage and reduces the risk of fire, contributing to the overall functionality of the dryer. This mechanism also aids in maintaining proper airflow and energy efficiency while preventing clothes from overdrying.
