York S1-02435311000 Pressure Switch -0.65" PF SPNO WC

The York S1-02435311000 is a genuine Source 1 OEM pressure switch designed for York, Luxaire, and Coleman gas furnaces. As a primary safety device, this switch monitors the negative pressure created by the draft inducer motor, ensuring the flue is clear and combustion air is flowing before allowing the ignition sequence to begin.

Technical Performance

This high-precision switch is factory-calibrated to a -0.65" WC (Water Column) set point. Featuring a Single Pole Normally Open (SPNO) configuration, it is engineered to close the electrical circuit only when the specific venting pressure is reached. Being a Genuine Source 1 part ensures the internal diaphragm is resistant to the corrosive effects of flue gas condensate, preventing the nuisance trips common with universal "adjustable" switches.

Key Features and Function

  • Feature 1: Precision Pressure Sensing – Calibrated to -0.65" WC to ensure exact safety thresholds are met for combustion.
  • Feature 2: OEM Safety Integration – Designed to communicate directly with York control boards for seamless fault code reporting.
  • Feature 3: SPNO Configuration – Single Pole Normally Open logic ensures the furnace fails-safe if pressure is lost or the inducer fails.
  • Feature 4: Durable Diaphragm – Built with heavy-duty materials to withstand thousands of cycles in high-humidity venting environments.

🛠️ HVAC Depot Pro Tip: The "Tubing Trap"

When replacing an S1-02435311000, always inspect the rubber pressure tubing for cracks or "kinks." Even a perfect switch won't close if the tube has a pinhole leak or if the tiny metal orifice on the inducer housing is clogged with rust. Give it a quick poke with a paperclip!

The S1-02435311000 is a direct OEM replacement for the following part numbers:

  • OEM Numbers: 024-35311-000, 02435311000, S1-024-35311-000
