Nordyne 632673 Pressure Switch

Nordyne 632673 Pressure Switch

The Nordyne 632673 Inducer Pressure Switch is a critical safety component designed for high-efficiency forced-air furnaces. As a genuine OEM replacement part, this single-pole, single-throw (SPST) switch is factory-calibrated to a 1.13 in. W.C. set point, ensuring the draft inducer motor establishes proper static pressure before the ignition sequence begins. This furnace air pressure switch prevents hazardous operation by monitoring the venting system for blockages or inducer failure, providing a reliable 1.13-inch water column actuation threshold essential for HVAC combustion safety.

Engineered for compatibility with Nordyne, Miller, Intertherm, and Revolv M-series condensing units, the 632673 features a rugged ABS housing and 1/4-inch quick-connect terminals for streamlined field installation. This draft inducer pressure switch is the direct spec-match for mobile home and residential gas furnaces requiring specific pressure tolerances to avoid nuisance lockouts or "pressure switch open" fault codes. By maintaining precise airflow verification, this component ensures consistent burner performance across varying atmospheric conditions.

Key Benefits
  • Precise 1.13 in. W.C. Actuation: Factory-set to ensure exact draft confirmation for high-efficiency gas furnaces.
  • OEM Compatibility: Direct replacement for Nordyne 632673, maintaining factory safety protocols in Intertherm and Miller units.
  • Industrial Build Quality: Features a durable diaphragm and corrosion-resistant housing for long-term reliability in high-temperature environments.
  • Simplified Wiring: Equipped with standard male spade terminals for fast connection to the 24V control circuit.
Common Questions

What causes a furnace pressure switch to stay open?
An open switch signal often indicates a blocked vent pipe, a failing inducer motor, or moisture buildup in the pressure tubing. If the inducer is running but the switch does not close at the 1.13 in. W.C. threshold, the switch or the pneumatic signal may be compromised.

Can I use a universal pressure switch to replace the Nordyne 632673?
While universal switches exist, using the genuine Nordyne 632673 is recommended to ensure the set point precisely matches the manufacturer’s combustion airflow requirements for safety and efficiency.

How do I test the 632673 pressure switch?
Technicians should use a manometer to verify the inducer is pulling at least 1.13 in. W.C. of negative pressure and use a multimeter to check for continuity across the terminals when the set point is reached.
