The Lennox 60M59 is an OEM replacement L160-40F automatic reset limit switch engineered to protect furnaces and heating systems from overheating conditions. When supply air temperatures reach the set point, the limit switch interrupts the burner circuit, preventing heat exchanger damage and ensuring safe system operation.
How It Works
This automatic reset limit switch opens the circuit at 160°F and automatically resets once temperatures fall by 40°F (reset point: 120°F). The auto-reset design eliminates the need for manual intervention after a high-temperature event, minimizing system downtime and service calls.
