Description
The Rheem-Ruud PD425169 is an OEM replacement pressure switch engineered specifically for Rheem and Ruud heating systems. Pressure switches play a critical role in furnace safety — they verify that the draft inducer motor is operating correctly and that proper venting pressure is established before allowing the ignition sequence to proceed, helping to prevent unsafe combustion conditions.
Key Features
- OEM Rheem-Ruud replacement pressure switch — SKU PD425169
- Set points: +1.08″ W.C. (positive) and -0.60″ W.C. (negative)
- Designed to confirm adequate draft pressure before ignition
- Helps prevent unsafe furnace operation due to blocked flues or failed inducer motors
- Direct OEM fit for compatible Rheem and Ruud furnace models
- Supports reliable, code-compliant furnace operation
Application
This pressure switch is intended for use in Rheem and Ruud gas furnaces as a direct OEM replacement. It monitors the pressure differential created by the draft inducer blower to confirm safe venting conditions. If the required pressure is not achieved — due to a blocked vent, failed inducer motor, or other fault — the switch prevents the furnace from proceeding through the ignition sequence, protecting both equipment and occupants.
Installation Notes
- Always verify compatibility with your specific furnace model before installation
- Refer to the furnace service manual for wiring diagrams and replacement procedures
- Disconnect power to the unit before servicing
- Inspect inducer hose and port for cracks, clogs, or moisture before replacing the switch
