Lennox 24L26 Limit Switch One of the primary benefitsThe Lennox 24L26 Limit Switch is a critical OEM furnace safety control engineered for high static environments and precise thermal monitoring. This automatic reset limit switch is designed to protect the heat exchanger and blower assembly from thermal runaway by interrupting the burner circuit when temperatures reach the 200F high limit trip point. Once the plenum cools to the 160F reset temperature, the switch automatically closes to resume normal
