Lochinvar & A.O. Smith 100111630 Pressure Switch

Lochinvar & A.O. Smith 100111630 Pressure Switch

The Lochinvar & A.O. Smith 100111630 Pressure Switch is a critical safety component designed for precise air pressure detection in high-efficiency water heaters and boiler systems. Specifically calibrated to a 1.00" WC (Water Column) set point, this SPST (Single Pole Single Throw) switch features a normally open (NO) contact configuration. It is engineered to monitor the combustion chamber pressure, ensuring the blower motor is sufficiently venting flue gases before the ignition sequence begins. Built to the exact OEM specifications of Lochinvar and A.O. Smith, this switch is a direct replacement for part numbers 100111630 and 9006953005. Its robust diaphragm construction handles the cycling requirements of commercial and residential condensing water heaters, providing the reliability required by contractors to prevent nuisance lockouts and carbon monoxide risks associated with improper venting.

Key Benefits:
  • OEM Precision: Calibrated specifically for a 1.00" WC trip point to meet factory safety tolerances.
  • System Compatibility: Direct fit for A.O. Smith GPHE-50 models and various Lochinvar high-efficiency appliances.
  • Durable Construction: High-grade diaphragm and normally open contacts designed for industrial-level duty cycles.
  • Safety Compliance: Prevents burner operation during vent blockage or inducer fan failure.
Common Questions:

What are the symptoms of a failing pressure switch in an A.O. Smith unit?
Technicians typically see "blocked vent" or "pressure switch open" fault codes on the digital interface. If the inducer motor is running but the ignition doesn't spark, the 100111630 may be failing to close under the 1.00" WC load.

Is this switch compatible with other water column ratings?
No. Pressure switches are model-specific. Using a switch with a different WC rating than the original 100111630 specification can lead to dangerous combustion conditions or persistent system errors.

Can I use this as a cross-reference for American Water Heater parts?
Yes, this is the genuine OEM replacement for American Water Heater and John Wood units that call for the 100111630 or 9006953005 part numbers.
