York S1-324-35972-000 Pressure Switch Kit

As an experienced HVAC contractor, you know that a faulty furnace pressure switch is one of the most common causes of no-heat calls. The York S1-324-35972-000 Pressure Switch Kit is the precise OEM furnace replacement part required for maintaining the safety sequence of mid-efficiency and mobile home gas furnaces. Calibrated to a critical 0.10" WC (Water Column) trip point, this vacuum air pressure switch ensures the inducer motor is drafting correctly before allowing the ignition process to proceed. This genuine Source1 kit—also recognized under part number 324-35972-000—is designed for York, Coleman, and Luxaire equipment, specifically the DGAA, DGAH, DGPA, and DGPH series. Installing this induction fan pressure switch guarantees that your system monitors flue vacuum levels with the accuracy required to prevent unsafe combustion or rollout conditions. When performing HVAC pressure switch troubleshooting, using this factory-spec kit ensures a seamless fit and exact electrical termination for long-term reliability on the job site.

• Precise 0.10" WC Calibration: Factory-set to ensure the furnace only fires when the correct venting pressure is established.
• Broad Unit Compatibility: Directly supports popular York DGAA056 and DGAH mobile home furnace models.
• OEM-Grade Construction: Built by Source1 to meet rigid manufacturer specifications for safety and performance.
• Reduced Callbacks: Using a genuine HVAC safety switch ensures your repairs hold up under peak winter loads.

What are the symptoms of a failing S1-324-35972-000 switch?
If the furnace inducer motor runs but the igniter never glows, or if you see a "pressure switch stuck open" error code on the control board, the 0.10" WC switch is likely failing to close or detect the vacuum.

Can I use a universal switch as a substitute?
While universal switches exist, they often lack the exact 0.10" WC set point required for specific York pressure switch kits. Using an incorrect rating can lead to intermittent shutdowns or safety hazards, so sticking to the S1-324-35972-000 is recommended for these specific DGAA and DGAH units.

Does this kit include everything needed for installation?
Yes, this pressure switch kit is designed for straightforward field replacement with standard wiring terminals and hose ports for a fast swap-out during service calls.
