Lochinvar & A.O. Smith 100112168 Switch
The Lochinvar & A.O. Smith 100112168 Switch is a critical safety component designed for low gas pressure detection in high-efficiency heating systems. As a genuine OEM replacement part, this low gas pressure switch is engineered to monitor the incoming fuel supply and interrupt the burner circuit if pressure drops below the required threshold, preventing unstable combustion and potential equipment damage. It is a direct-fit solution for Lochinvar Knight boilers and various A.O. Smith water heaters, ensuring the system maintains 4 inches water column (WC) or the specific setpoint required for safe ignition.
For service technicians performing maintenance or emergency repairs, using the Lochinvar 100112168 ensures full compatibility with the internal control logic of the appliance. This HVAC pressure switch features a compact design with robust electrical contacts capable of handling 24V control circuits. Proper integration of this gas pressure safety switch is essential for meeting code requirements on commercial and residential gas-fired equipment. To ensure a precise match, verify the part number against your unit's specific model and serial number before installation.
Key Benefits- Ensures safe boiler operation by preventing low-pressure flame rollout or nuisance flame failures.
- Designed for high-accuracy gas pressure monitoring to protect downstream gas valves and burners.
- Genuine 100112168 OEM part ensures exact mounting and terminal alignment for faster field replacements.
- Helps maintain the combustion efficiency and operational reliability of industrial water heaters and boilers.
What are the symptoms of a failing low gas pressure switch?
Common indicators include intermittent "low gas pressure" lockout codes on the control board or the system failing to initiate the ignition sequence despite adequate supply pressure.
Is the 100112168 a universal part for all A.O. Smith units?
No, this is a model-specific component. While it fits many Lochinvar Knight and A.O. Smith models, it must be verified against the manufacturer’s parts list to ensure the correct setpoint and electrical rating.
Can this switch be used for high-pressure gas applications?
No, this part is specifically calibrated as a low gas pressure switch and should only be used in low-pressure sensing lines as specified by the equipment manufacturer.
