Lochinvar & A.O. Smith 100093633 Switch

The Lochinvar & A.O. Smith 100093633 Pressure Switch is a critical OEM safety component engineered for high-efficiency water heating systems, including Polaris water heaters. This 0.85" WC pressure switch operates as a normally open contact that closes when the inducer fan generates sufficient static pressure, ensuring the combustion cycle only proceeds under safe venting conditions. As a direct Polaris IS22085 replacement, this kit provides a precise set point of 0.85 inches water column, specifically calibrated to prevent nuisance tripping and pressure switch lockout codes. Technicians should verify the water heater pressure switch calibration matches the data plate to maintain AFUE ratings and proper flue gas drafting. This genuine A.O. Smith performance part is compatible with various Lochinvar and A.O. Smith commercial and residential platforms, offering a robust solution for troubleshooting exhaust pressure switch failures in condensing water heaters.

Key Benefits for Technicians:
  • OEM Calibration: Exact 0.85" WC set point ensures precise blower proving and system safety.
  • Drop-in Compatibility: Designed specifically for Lochinvar boiler parts and A.O. Smith systems using the IS22085 configuration.
  • Complete Integration: Includes the Polaris IS22085 pressure switch kit components for a comprehensive field repair.
  • Reliable Signal: High-quality electrical contacts prevent high-resistance readings that cause intermittent ignition failures.
Common Questions & Technical Support:

What causes a Lochinvar 100093633 pressure switch to stay open?
Usually, this occurs due to a blocked flue, a failing inducer motor, or moisture accumulation in the sensing tubes. Always check for 0.85" WC of vacuum at the switch before replacing the component.

Can I use a universal pressure switch instead of the 100093633?
It is not recommended. This OEM pressure switch is calibrated for a specific pressure differential required to maintain the safety certification of the appliance.

How do I test the Lochinvar 100093633?
Using a manometer, verify the system is pulling at least 0.85" WC. Use a multimeter to check for continuity across the terminals once the set point is reached.
