Lochinvar & A.O. Smith 100111732 Pressure Switch
The Lochinvar & A.O. Smith 100111732 Pressure Switch is a critical safety component engineered for high-efficiency boilers and commercial water heaters. This .75" WC air pressure switch (normally open) is designed to monitor the pressure differential across the heat exchanger, ensuring that the inducer motor is moving a sufficient volume of combustion air before the ignition sequence initiates. As a veteran-preferred OEM replacement part, the 100111732 is the designated update for the legacy 9007122015 kit, offering improved reliability in detecting blocked vent conditions or intake obstructions. This HVAC air pressure switch features a robust internal diaphragm calibrated to precise tolerances, maintaining system integrity by preventing operation under hazardous low-airflow conditions. It is compatible with a wide range of Lochinvar and A.O. Smith water heaters, providing a direct-fit solution that eliminates the need for field modifications and ensures your equipment meets original factory performance standards.
Key Benefits:
- OEM Precision: Genuine Lochinvar 100111732 factory component ensures exact set-point calibration at -.75" WC.
- Enhanced Safety: Acts as a primary limit control to prevent combustion in the event of flue gas recirculation or blocked intakes.
- Direct Cross-Reference: Serves as the official successor to the 9007122015 pressure switch kit for seamless maintenance.
- Industrial Build: Engineered to withstand the thermal cycling and high-demand environments typical of commercial HVACR systems.
Common Questions:
- How do I know if the 100111732 switch is failing? If your boiler is stuck in the pre-purge cycle or throwing a "Pressure Switch Did Not Close" error code, use a manometer to verify if the inducer is pulling the required -.75" WC. If the pressure is sufficient but the switch remains open, a replacement is necessary.
- Is this switch compatible with residential A.O. Smith models? Yes, this part is used across several residential and light commercial platforms. Always verify the part number against your specific unit's data plate or service manual.
- Can I adjust the set point on this switch? No. This is a factory-calibrated safety device. Field adjustments can lead to unsafe combustion conditions and should never be attempted.
