Ruud pd425144 Pressure Switch 0.30 Wc Single Port

Product Description

The RUUD pd425144 is a single-port pressure switch kit rated at 0.30 inches water column (WC), designed for use in residential gas furnace systems. Pressure switches are safety control devices that monitor the negative pressure produced by the inducer motor during furnace operation. If the required draft pressure is not established, the switch prevents ignition, protecting the heat exchanger and venting system from hazardous conditions. This kit is installed by licensed HVAC technicians as part of routine service or replacement of failed pressure switch assemblies in RUUD gas furnace models.

This pressure switch kit is specified for the RUUD R96PA, R96TA, and R96VA series gas furnaces. These are 96 percent AFUE, two-stage or modulating residential furnace platforms commonly installed in single-family homes. The single-port configuration and 0.30 WC set point match the inducer pressure requirements of these specific furnace lines, making it a direct OEM-style replacement for failed or out-of-spec pressure switch assemblies in field service applications.

Key Features

• 0.30 inches WC set point for precise inducer draft monitoring
• Single-port design matches factory configuration on compatible RUUD furnace models
• Functions as a safety interlock to prevent ignition without proper draft pressure
• Supplied as a complete kit for straightforward field replacement
• OEM-specified part number for R96PA, R96TA, and R96VA furnace series

Compatibility

Designed for use with RUUD R96PA, R96TA, and R96VA series gas furnaces as stated by the manufacturer.

Installation Notes

Installation should be performed by a licensed HVAC technician. Before servicing, shut off power to the furnace at the disconnect or breaker and turn off the gas supply. The pressure switch connects to the inducer housing port via a rubber hose and to the control board via low-voltage wiring. Verify hose condition and port integrity during replacement, as cracked hoses are a common cause of pressure switch faults.
