Lochinvar & A.O. Smith 100166238 Switch
The Lochinvar & A.O. Smith 100166238 Gas Pressure Switch is a critical safety component designed for high-performance gas-fired boilers and commercial water heaters. Featuring a 1-20" WC adjustable range, this manual reset gas pressure switch ensures system integrity by monitoring incoming or manifold gas pressure. If pressures deviate from the calibrated setpoint, the switch initiates a safety lockout, preventing hazardous combustion conditions. Built for professional HVACR environments, this OEM replacement part provides the precise sensitivity required for modulating systems where stable pressure is non-negotiable. Whether you are servicing a Lochinvar Knight boiler or an A.O. Smith Cyclone series, this switch integrates seamlessly with existing control strings. The durable housing and technical design are engineered to withstand the demanding thermal cycles of commercial mechanical rooms. Ensure your clients' equipment remains code-compliant and operational by utilizing authentic Lochinvar boiler controls that meet exact manufacturer specifications for gas pressure monitoring and system protection.
Key Benefits- Precise Pressure Monitoring: Adjustable 1-20" water column range allows for fine-tuning based on specific manifold or supply requirements.
- Manual Reset Safety: Integrated manual reset mechanism prevents automatic restarts during unsafe pressure fluctuations, requiring technician intervention.
- Broad Compatibility: Genuine A.O. Smith and Lochinvar part ensures a perfect fit for a wide range of commercial boilers and high-efficiency water heaters.
- Rugged Construction: Designed for reliability in high-cycle commercial heating applications, reducing nuisance trips and emergency service calls.
What are the symptoms of a failing gas pressure switch?
Common signs include the system remaining in a safety lockout, the burner failing to ignite despite a call for heat, or error codes specifically referencing gas pressure faults on the control board.
How do I adjust the setpoint on the 100166238?
Use a calibrated manometer to monitor the gas line while adjusting the internal dial to your required pressure threshold within the 1-20" WC range. Always verify the manufacturer's recommended settings for the specific model being serviced.
Can this switch be used for both high and low gas pressure monitoring?
This specific model is engineered as a manual reset gas pressure switch typically used to detect pressure drops or spikes depending on its orientation in the safety string. Always consult the wiring diagram to confirm its role in the limit circuit.
