Nordyne 632515R Pressure Switch

The Nordyne 632515R Pressure Switch is a critical OEM replacement part designed for high-efficiency gas furnaces and air handlers. Engineered as a dual pressure switch, this component performs a vital safety function by monitoring both negative and positive pressure conditions within the combustion assembly. This unit is the direct factory-authorized successor to the retired Nordyne 632515, featuring precise set points calibrated at -0.73" WC (vacuum) and 0.43" WC (positive pressure). These specific thresholds ensure the inducer motor is moving sufficient air for safe ignition and consistent combustion, protecting the system from dangerous exhaust build-up or blocked vent conditions.

For field technicians, the 632515R maintains a Normally Open (NO) configuration and incorporates 1/4" male quick-connect spade terminals for seamless wiring integration. The dual-stage design utilizes 1/4" barbed fittings to accommodate standard vacuum and pressure tubing. This HVAC pressure switch is fully compatible with Nordyne, Miller, and Intertherm furnaces, providing a reliable solution for diagnostic codes related to pressure switch stuck open or closed. Built with a durable thermoplastic housing, it is rated for operating temperatures between -40?F and 150?F, ensuring stable performance in extreme attic or mechanical room environments.

• Direct OEM Replacement: Safely replaces the obsolete Nordyne 632515 with identical mounting footprints.
• Dual-Function Protection: Monitors both inducer vacuum and positive pressure for comprehensive airflow verification.
• Precision Calibration: Factory-set at -0.73" / 0.43" WC to match original equipment specifications for N-Series furnaces.
• Universal Terminal Compatibility: Standard 1/4" spade connectors and barbed ports eliminate the need for field modifications.

• Can I use this to replace a single-stage switch? No, the 632515R is a dual pressure switch specifically for 2-stage systems or units requiring vacuum and positive pressure monitoring.
• Does it include the mounting bracket? This is the switch only; it is designed to snap into the existing factory mounting bracket.
• How do I test this switch? Use a calibrated manometer to verify it closes at -0.73" WC on the negative side and 0.43" WC on the positive side.
