Mounted near the heat exchanger, it monitors plenum temperature and opens the circuit to shut down the burners if things get too hot — most commonly when airflow drops due to a dirty filter or a failed blower. It's a critical safety device calibrated to your Lennox unit's exact trip point.\u003c\/p\u003e\u003cp\u003eA failing \u003cstrong\u003e56L60\u003c\/strong\u003e often causes short cycling on heat, the furnace shutting down mid-cycle, or no heat at all if the switch fails open. A switch that trips repeatedly can also be flagging a real airflow or heat-exchanger problem worth investigating.\u003c\/p\u003e\u003cp\u003eOEM is essential on a safety control. The genuine Lennox \u003cstrong\u003e56L60\u003c\/strong\u003e is set to the precise open\/close temperatures your furnace requires — a generic switch with the wrong setpoint can nuisance-trip or, worse, fail to protect the equipment.
