Product description

The Lennox H5875 Blower Switch is a precision thermal control device designed to automate the operation of your heating system's fan. This switch is calibrated with a 140-20F temperature range, meaning it activates the blower when the heat exchanger reaches 140 degrees Fahrenheit and shuts it down once the temperature drops back by 20 degrees. This ensures that the fan only runs when there is sufficient heat to warm your home, preventing the distribution of cold air. By automating the blower cycle, this switch improves comfort and enhances the energy efficiency of the appliance. Its compact, snap-action design allows for quick response to temperature changes, providing reliable switching for thousands of cycles. This switch is a critical component for maintaining the proper sequence of operation in Lennox furnaces and stoves, ensuring a consistent and comfortable airflow throughout the heating season.
