Westinghouse 632514 Furnace Pressure Switch 0.63 in Wc

Product Description

The WESTINGHOUSE 632514 is a furnace pressure switch rated at 0.63 inches water column (WC), designed for use in 2-stage condensing and non-condensing gas furnace applications. Pressure switches are safety-control devices that monitor negative pressure produced by the inducer motor. If the correct pressure is not established, the switch prevents the furnace from advancing through the ignition sequence. This part is a direct OEM-style replacement installed by licensed HVAC technicians during routine service or component-level repair.

This pressure switch is specified for use on the PGC2 2-stage condensing and non-condensing furnace platform. The 2-stage design means the switch is calibrated to the pressure differentials produced during both low-fire and high-fire inducer operation. Correct setpoint matching to the furnace model is critical for proper ignition sequence control and safe operation.

Key Features

• Rated at 0.63 inches WC for precise pressure differential sensing
• Compatible with 2-stage furnace operation, covering both low-fire and high-fire inducer cycles
• Serves as a safety lockout device to prevent ignition if inducer pressure is insufficient
• OEM-specified replacement for the PGC2 furnace platform

Compatibility

Designed as a replacement pressure switch for the WESTINGHOUSE PGC2 2-Stage Condensing and Non-Condensing Furnace.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the furnace at the disconnect switch or breaker before removing or installing any control components. Verify the replacement switch setpoint matches the original part number before installation, as incorrect pressure ratings will cause nuisance lockouts or unsafe operation. Refer to the furnace wiring diagram for correct hose port and terminal connections.
