Description
The Reznor RZ146464 Fan Control Limit Switch regulates blower operation and temperature limiting in compatible furnace and air handling equipment, featuring a 135F close and 40F open temperature range for controlled cycling. The switch reacts to internal temperature changes by activating or interrupting connected circuits once preset conditions are reached. Mounted within the heat section or control compartment, it assists with airflow management and overheating prevention during equipment operation. Proper temperature response and cycling coordination contribute to stable airflow control and regulated operation in HVAC systems across warm air furnaces and packaged heating units.
