Lochinvar & A.O. Smith 100110095 LWCO

The Lochinvar & A.O. Smith 100110095 is a critical safety component designed for high-performance hydronic heating systems. This heavy-duty 120V low water cut-off (LWCO) includes a high-conductivity probe to ensure precise water level monitoring, protecting heat exchangers from dry-fire conditions. Engineered as a direct OEM replacement part, this unit offers seamless integration into residential and commercial boiler controls. It provides a reliable fail-safe by interrupting the burner circuit if water levels drop below the safe operating threshold. For technicians servicing legacy equipment, the 100110095 is the official replacement for the obsolete 9004819105 water cutoff. Built to withstand the rigorous demands of mechanical rooms, this 120V LWCO with probe ensures field reliability and maintains the structural integrity of the boiler assembly. Use this genuine boiler safety control to maintain factory specifications and ensure consistent system uptime in demanding HVACR environments.

• Direct OEM Compatibility: Perfectly replaces obsolete part numbers, including 9004819105, ensuring exact fit and function.
• Integrated Probe Sensing: Utilizes advanced probe technology for electronic low water detection without moving domestic parts that can scale or foul.
• Industrial Build Quality: Housing and internal relays are designed for high-cycle applications in 120V control circuits.
• Critical Safety Shutdown: Provides immediate burner interruption to prevent catastrophic equipment failure during loss of system pressure.
