Lochinvar & A.O. Smith 100112658 Pressure Switch
The Lochinvar & A.O. Smith 100112658 Pressure Switch is a critical safety and operational component designed for high-efficiency water heaters and boiler systems. Specifically calibrated at a 0.27" WC (Water Column) set point, this diaphragm-style switch ensures the vent blower or inducer motor is moving sufficient air to support safe combustion. As a genuine Honeywell IS20451-6168 OEM part, it delivers the precise switching required to prevent ignition during restricted venting or blower failure scenarios. This Normally Open (NO) switch is built for high-performance residential and commercial applications where maintaining exact pressure differentials is non-negotiable for system uptime.
This unit is a direct replacement for Lochinvar 100080047, as well as several discontinued or superseded numbers including Cleveland Controls NS2-1306-00, NS2-1563-00, and 9008267015. For contractors performing field service, this switch is the standard for Lochinvar and A.O. Smith water heater repair, providing reliable pressure regulation across diverse HVAC and commercial heating systems. Its robust construction is engineered to withstand the cycling demands of modern high-recovery units, ensuring your boilers and water heaters operate at peak 0.27" WC pressure setting specifications without premature failure.
Key Benefits:- Direct OEM Compatibility: Verified as the official replacement for part numbers 100080047, NS2-1306-00, and IS20451-6168.
- Precision Safety: Pre-calibrated at 0.27" WC to ensure accurate air prover functionality and prevent unsafe combustion.
- Durable Construction: Engineered by Honeywell for high-cycle industrial machinery and heavy-duty HVAC applications.
- Versatile Application: Suitable for use in a wide range of A.O. Smith and Lochinvar residential and commercial systems.
What are the symptoms of a failing 100112658 pressure switch?
Common signs include the inducer motor running continuously without the igniter glowing, or the control board throwing a "3 blinks" error code indicating the pressure switch is stuck open. This often prevents the ignition sequence from starting.
Can I use this to replace a switch with a different Water Column rating?
No. Pressure switches are safety-critical and model-specific. Replacing a 0.27" WC switch with a different rating can cause safety hazards or intermittent system lockouts. Always match the manufacturer’s specified set point.
Is this switch compatible with A.O. Smith water heaters?
Yes, this is a genuine Lochinvar & A.O. Smith OEM part. It is designed specifically for integration with their high-performance water heating and boiler lines.
