Product Details

Description

The Lennox L140-40F High Limit Switch is a vital safety component designed for HVAC systems and forced-air furnaces. This SPDT (Single Pole Double Throw) fan disc control switch acts as a thermal safeguard, monitoring internal temperatures to prevent equipment overheating. When the system reaches its 140°F limit, the switch automatically interrupts the heating circuit to protect the appliance from damage. With its convenient auto-reset feature, the switch restores operation once the temperature cools by its 40°F differential. This high-quality replacement part is essential for maintaining the safe and efficient operation of residential and commercial heating units, ensuring reliable climate control and long-term durability of your HVAC equipment.
