Lochinvar & A.O. Smith 100271883 Pressure Switch
Maintain peak combustion safety with the Lochinvar & A.O. Smith 100271883 Pressure Switch, a critical OEM component designed for low gas pressure monitoring. As a veteran-grade K low gas pressure switch, this device acts as an essential safety interlock, continuously sensing the inlet gas supply to ensure it meets the minimum operational threshold of approximately 3.1" W.C. If the supply pressure drops below the setpoint, the internal contacts open, immediately breaking the safety circuit to prevent unstable burner operation or delayed ignition. This genuine replacement pressure switch is engineered for high-recovery commercial water heaters and high-efficiency boilers, including the BTH 120-300 series. Its robust construction resists vibration and internal fouling, ensuring the gas-fired appliance safety switch provides reliable continuity during the pre-purge and ignition sequences. For technicians managing Lochinvar boiler parts or A.O. Smith commercial water heater maintenance, utilizing this exact factory-spec switch is mandatory to maintain the system's UL/CSA combustion certification and ensure seamless integration with the integrated control board.
Key Benefits- Precise 3.1" W.C. Setpoint: Specifically calibrated to detect low-pressure conditions before nuisance flame failures or equipment damage occurs.
- OEM Compatibility: Designed for seamless fitment in A.O. Smith BTH models and various Lochinvar commercial heating units.
- Enhanced System Reliability: High-quality internal diaphragm and electrical contacts ensure consistent performance in demanding mechanical rooms.
- Automated Safety Interlock: Provides immediate feedback to the ignition control to verify safe gas supply pressure before every start-up cycle.
How do I verify if the 100271883 switch is causing a lockout?
Check for continuity across the terminals when the gas supply is active; if the pressure is above 3.1" W.C. but the circuit remains open, the internal diaphragm or contacts have likely failed.
Is this switch a manual or automatic reset?
This specific low gas pressure switch typically functions as an automatic reset safety device, though it should be verified against your specific equipment’s wiring diagram for manual reset interlock configurations.
What are the symptoms of a failing gas pressure switch?
The most common indicators are intermittent "Low Gas Pressure" fault codes, failure to start the ignition trial despite adequate supply pressure, or erratic cycling during high-demand periods.
