York S1-024-34561-000 Pressure Switch

The York S1-024-34561-000 Pressure Switch is a critical safety and operational component designed for high-efficiency York gas furnaces and air handlers. Engineered with a set point of .95/.4" WC (inches Water Column), this OEM York replacement part monitors the pressure differential within the combustion chamber to ensure the inducer motor is moving sufficient air for safe ignition. This SPDT pressure switch (Single Pole Double Throw) handles up to 15A at 125/250 VAC, providing robust electrical switching for heavy-duty HVAC cycles.

Field-proven for compatibility with specific models like the GF9S080C16DH11J, this switch prevents hazardous operation by interlocking the gas valve with proper venting. When troubleshooting common furnace pressure switch stuck open codes or inducer motor short cycling, replacing a degraded sensor with this exact-spec HVAC pressure control ensures the system maintains its original factory safety parameters. The dual-pressure range is calibrated to high precision, ensuring reliable performance in demanding residential and light commercial applications.

• OEM Precision: Calibrated specifically to .95/.4" WC to match York factory airflow requirements.
• High Electrical Capacity: Rated at 15A for long-term durability in 24V furnace control circuits.
• Safety Interlock: Crucial for preventing ignition if the vent pipe or heat exchanger is obstructed.
• Universal SPDT Configuration: Offers versatile wiring options for diverse HVAC mechanical switch applications.

• What causes a "Pressure Switch Stuck Open" error? This is often due to a blocked flue, a failing inducer motor, or cracked vacuum tubing, though common mechanical failure of the internal diaphragm also necessitates a replacement switch.
• Can I use a switch with a different "WC rating? No. Using a switch with an incorrect Water Column rating can lead to premature shutdowns or, more dangerously, allow the furnace to run with inadequate venting.
• Is this switch compatible with 24V systems? Yes, while rated for up to 250 VAC, it is standard for 24V control boards found in modern York heating units.
