Westinghouse 632561 Gas Furnace Pressure Switch 2-stage

Product Description

The WESTINGHOUSE 632561 is a two-stage pressure switch designed for condensing gas furnaces. It monitors negative pressure created by the inducer motor during furnace operation, confirming that proper draft conditions exist before allowing the control board to advance through the ignition sequence. Rated for two setpoints at 1.00 and 0.30 inches water column (WC), this switch provides the staged pressure sensing required for two-stage furnace operation. Installation is performed by licensed HVAC technicians as part of a diagnostic replacement or scheduled service procedure.

This pressure switch is specified for use on the 060-VB condensing gas furnace. Condensing furnaces operate with sealed combustion and secondary heat exchangers, making accurate pressure switch operation critical to safe ignition lockout and fault protection. A failed or out-of-spec pressure switch on a two-stage system can result in lockout codes, short cycling, or failure to advance to second-stage heat. Replacing with the correct OEM-specified part number ensures proper setpoint calibration for the 060-VB platform.

Key Features

• Two-stage pressure sensing at 1.00 and 0.30 inches WC setpoints
• Designed specifically for condensing gas furnace applications
• OEM-specified replacement for the 060-VB condensing gas furnace
• Monitors inducer draft to protect ignition sequencing and prevent unsafe operation

Compatibility

Specified for use on the 060-VB Condensing Gas Furnace per manufacturer application data.

Installation Notes

This part is installed by licensed HVAC technicians. Shut down furnace power at the disconnect and set the thermostat to the off position before beginning any pressure switch service. The pressure port tubing connections should be inspected for cracks, blockages, or moisture during replacement. Verify that the replacement switch matches both the stage count and the WC setpoints of the original before returning the system to operation.
