Functioning as a high limit control, this fan disc switch monitors internal temperatures to prevent the appliance from overheating. The switch is engineered with an automatic reset feature for seamless operation: it is calibrated to trip and open the circuit when temperatures reach 150°F, protecting your system from thermal damage, and will automatically close to restore function once the unit cools to 110°F.
