Product Details

Description

Ensure your heating system operates safely and efficiently with this professional-grade Fan and Limit Switch. Designed as a critical safety and operational component for forced-air furnaces, this dual-function control switch regulates the blower fan's cycle while providing essential protection against system overheating. The high-limit sensor monitors the heat exchanger's temperature, automatically cutting off power to the heating elements or burners if the system exceeds safe thermal parameters. Simultaneously, the fan control ensures the blower only activates once the air is sufficiently warmed and continues running until the residual heat is distributed. This replacement thermal disc is an essential repair part for HVAC systems experiencing issues with constant fan operation, short-cycling, or safety shut-offs.
