Lochinvar & A.O. Smith 100112659 Pressure Switch
The Lochinvar & A.O. Smith 100112659 Pressure Switch is a critical safety component designed for Series 200/201 Power Vent Heaters and high-efficiency commercial gas water heaters. This genuine OEM replacement part features a precise 0.37" WC (Water Column) set point, ensuring the inducer motor provides sufficient draft before allowing the ignition sequence to proceed. Engineered for normally open operation, it effectively monitors the vacuum in the combustion chamber to prevent hazardous operation under blocked flue or intake conditions.
As a veteran technician, you know that identical to IS20451-6169, this 0.37" pressure switch is the updated version of the legacy 9008268015. It utilizes a durable sensing diaphragm housed in a robust casing to withstand the thermal and pressure fluctuations common in HVAC inducer assemblies. When troubleshooting a 3-blink error code or TCO/Pressure Switch failed open status on GPVL-50 or Cyclone Xi models, this Lochinvar boiler part is the standard for restoring reliable system cycling and air proving functionality.
Key Benefits- OEM Compatibility: Specifically calibrated for A.O. Smith and Lochinvar power vent systems, ensuring exact 0.37-inch water column response.
- System Protection: Prevents the burner from firing if the draft inducer fails or if there is an obstruction in the venting, protecting the heat exchanger.
- Drop-in Replacement: Directly replaces part numbers 100112659, 9008268015, and IS20451-6169 without mounting modifications.
- Precision Reliability: High-quality electric contacts provide consistent switching logic for long-term performance in demanding commercial environments.
What are the signs of a failing 100112659 pressure switch?
Common indicators include the inducer motor running continuously without ignition, or the controller displaying a pressure switch lockout code. Technicians often find 0.37" switches stuck open due to diaphragm fatigue or moisture in the sensing line.
How do I test the 0.37" WC set point during service?
Use a digital manometer to measure the suction at the inducer port. If the vacuum exceeds 0.37" WC but the 100112659 pressure switch fails to close its 24V circuit, the internal diaphragm or contacts are likely compromised.
Can this switch be used in other power vent series?
While many switches look similar, this unit is specifically calibrated for a 0.37 inch water column. Installing a switch with a different set point can lead to unsafe combustion or frequent nuisance trips.
