Product Details

Description

The Lennox L170-40F Blue Label High Limit Switch is a critical safety component designed for furnace and HVAC systems. This fan disc style control switch acts as a fail-safe by monitoring the internal temperature of the heat exchanger. If the system exceeds a safe operating temperature of 170°F, the switch automatically interrupts power to prevent overheating and potential equipment damage. Once the temperature cools by the 40°F differential, the circuit resets. This high-quality replacement part is essential for maintaining the safe operation of residential and commercial heating units. If your furnace is short-cycling or failing to provide consistent heat, a faulty high-limit sensor may be the issue.
