This high-quality Fan Disc Limit Switch is a critical safety component designed for furnace and HVAC heating systems. Functioning as a high limit control, this thermal switch monitors the internal temperature of your heating equipment to prevent dangerous overheating. If the temperature exceeds the pre-set safety threshold, the switch automatically breaks the electrical circuit to shut down the heating element or burner, protecting your system from damage and ensuring home safety. This snap-action disc switch is also integral to regulating blower fan operation, ensuring the fan activates and deactivates at the appropriate thermal levels for peak energy efficiency. It is an ideal replacement part for malfunctioning thermal sensors or safety cut-offs in forced-air heating units.
