Westinghouse 632562 Inducer Pressure Switch 2-stage

Product Description

The WESTINGHOUSE 632562 is a dual-setpoint inducer pressure switch rated at 0.65 inches water column and 0.20 inches water column, designed for 2-stage condensing gas furnace applications. This pressure switch monitors negative pressure generated by the inducer draft motor to verify proper venting before allowing the furnace control board to advance through the ignition sequence. It is a direct replacement component installed by licensed HVAC technicians during routine maintenance, inducer assembly service, or furnace repair calls.

This switch is specified for use on 120-VD condensing gas furnaces. The dual-setpoint design supports 2-stage heating operation, providing a separate pressure trip point for low-fire and high-fire inducer speeds. Condensing furnace applications require precise pressure sensing due to the sealed combustion and secondary heat exchanger design, making accurate switch calibration critical to reliable furnace operation.

Key Features

• Dual setpoints at 0.65 inches WC and 0.20 inches WC for 2-stage inducer pressure sensing
• Designed for condensing gas furnace applications with sealed combustion systems
• Monitors inducer draft pressure to confirm safe venting before ignition
• OEM-style replacement for 120-VD series condensing gas furnaces

Compatibility

Designed for use on 120-VD condensing gas furnaces as specified by the manufacturer.

Installation Notes

Inducer pressure switches are installed by licensed HVAC technicians. Before servicing, shut off all electrical power to the furnace at the disconnect and set the thermostat to the off position. Inspect the pressure switch hose and port for blockage or cracking before installing the new switch, as hose faults are a common cause of nuisance switch failures. Work should comply with applicable local mechanical codes and the furnace manufacturer installation instructions.
