Lennox 36K28 Limit Switch 323613-751 Reduced Pressure Drop: Clean internalThe Lennox 36K28 is a critical safety component designed for precise thermal regulation within residential and light commercial Lennox furnace systems. This automatic limit switch is engineered to monitor heat exchanger temperatures, effectively interrupting the burner circuit if internal conditions exceed the safety threshold. Operating with a fixed range of 160 190F, it provides a vital fail safe against overheating caused by restricted airflow or
