Product Details

Description

This High Limit Switch is a vital safety component designed for heating and ventilation systems. As a fan disc-style thermal control, it acts as a fail-safe by monitoring the internal temperature of your appliance. If the unit reaches a dangerously high temperature, this limit control switch automatically breaks the electrical circuit to prevent overheating, protecting both the equipment and your home. Common in furnaces, air handlers, and heating units, this bimetal disc switch is essential for maintaining a safe and efficient HVAC system. Replacing a faulty high limit switch can restore proper cycling and ensure your heating element or burner operates within safe parameters.
