The Lennox 25J26 Limit Switch is a critical high-temperature safety component engineered for precision thermal monitoring in residential and commercial heating systems

9% pure wrot copper for superior thermal conductivity and corrosion resistance

or a failing blower motor which prevents heat from being stripped away from the heat exchanger efficiently

This industrial elastomer insert is a direct drop-in replacement

maintaining the integrity of the Type E valve is paramount for consistent downstream pressure regulation and system efficiency
