Lennox 26H65 Limit Switch Els PW 17895 high-conductivity connection to the pipingThe Lennox 26H65 Limit Switch is a critical safety component designed for precise thermal regulation within residential heating systems and air handlers. This OEM Lennox replacement part is a normally closed limit control that functions on a temperature dependent circuit: it is engineered to open when the internal cabinet or heat exchanger temperature reaches 180F and automatically resets (closes) once the temperature drops to 150F.
