Lochinvar & A.O. Smith 100327064 Switch
The Lochinvar & A.O. Smith 100327064 Switch is a critical OEM replacement part designed for high-performance commercial and residential heating systems. As a primary main power switch, this component ensures the safe manual isolation of the 120V circuit, allowing contractors to perform maintenance or diagnostic checks without fully depowering the mechanical room's sub-panels. Engineered for seamless HVAC system integration, it maintains the electrical integrity of Lochinvar boilers and A.O. Smith water heaters, preventing accidental current draw during service. When dealing with a water heater not heating or a boiler that refuses to cycle, verifying the power supply continuity at the switch is a standard first step in the HVAC troubleshooting process. This heavy-duty toggle switch is built to withstand the high-cycle demands of industrial environments, providing a reliable electrical disconnect for service technicians. Using genuine parts like the 100327064 ensures exact fitment and keeps the system within original manufacturer technical specifications for voltage and amperage handling.
Key Benefits for the Contractor:- Direct OEM Match: Purpose-built for Lochinvar and A.O. Smith equipment, eliminating the need for field modifications or bracket adjustments.
- Circuit Safety: Provides a robust physical break in the 120V power supply to protect downstream control boards and sensitive electronics.
- Compact Form Factor: Fits standard control housing covers, allowing for fast HVAC service and minimal downtime.
- High Cycle Life: Heavy-duty internal contacts are designed to handle the inductive loads of HVAC blower motors and ignition controls.
- How do I verify if the 100327064 switch is faulty? Use a multimeter to check for electrical continuity across the terminals in the 'ON' position. If the switch shows high resistance or an open circuit while engaged, it must be replaced.
- Is this switch compatible with 240V systems? This specific part is generally rated for 120V main power applications. Always verify the voltage requirements on your unit’s wiring diagram before installation.
- Do I need special tools for replacement? Most installations require only a 1/4" socket or standard screwdrivers to access the control housing cover and secure the mounting hardware.
