Manual reset limit switches are critical safety components that prevent automatic restart until the root cause of overheating is identified and corrected. When the switch trips due to excessive temperature, it must be manually reset by pressing the reset button after the system has cooled down. This design helps technicians identify persistent airflow problems, blower motor failures, or other issues that could lead to equipment damage or safety hazards.

This limit switch is compatible with various Bard HVAC furnaces and air handling units. Proper installation requires matching the temperature rating and mounting configuration to your specific equipment model.
