The RUUD PD425152 is a replacement pressure switch kit designed for use in gas furnace systems. The pressure switch monitors the negative pressure created by the inducer motor during furnace operation, confirming safe draft conditions before allowing ignition to proceed. This factory-sealed kit includes the necessary components for a direct OEM-style replacement. Licensed HVAC technicians perform this repair as part of standard furnace diagnostics and seasonal service work. The kit is built to restore proper operation when the original switch fails or reads out of spec.
This pressure switch kit is used on RUUD gas furnace models. It is suited for residential heating applications where the original switch has failed, is stuck open or closed, or has caused a lockout condition. Because the kit ships factory sealed, all components arrive ready for installation without the need to source additional hardware. This makes it a practical stocking part for HVAC service companies that regularly service RUUD furnace equipment.
Designed for use on RUUD furnace models U96VA and U97V-USA.
Installation should be performed by a licensed HVAC technician. Before servicing, shut off power to the furnace at the disconnect switch and allow the system to cool completely. Verify the new switch matches the pressure rating and port configuration of the original before connecting. Consult local codes and the furnace service manual for proper wiring and tubing reconnection procedures.
