Description
The York S1-324-35886-000 is a factory-authorized pressure switch kit engineered specifically for York two-stage, 96% AFUE high-efficiency gas furnaces. Pressure switches are a critical safety component in condensing furnaces — they verify that the inducer motor has established proper negative pressure before allowing the gas valve to open, protecting against flue gas spillage and unsafe combustion conditions.
Why Replace Your Pressure Switch Kit?
Over time, pressure switches can fail due to diaphragm fatigue, moisture exposure from condensate, or normal wear. A faulty pressure switch is one of the most common causes of furnace lockout and no-heat service calls. Using a genuine York OEM replacement kit ensures proper calibration, reliable operation, and compatibility with your specific furnace model — eliminating the guesswork of aftermarket substitutions.
