This high-quality Lennox auto-reset limit switch is a vital safety component designed for residential and commercial HVAC systems. Functioning as a high-limit control, this fan disc switch protects your furnace or heating unit from overheating by monitoring internal temperatures. If the system reaches a critical heat level, the switch automatically interrupts the circuit to ensure safe operation. Featuring an L175-40F calibration, it is engineered to trip at 175°F and reset once the temperature drops by 40°F, restoring normal heating cycles without the need for manual intervention. Ideal for professional maintenance and DIY repairs, this temperature-sensitive switch ensures the continued safety and efficiency of your heating equipment.
