York S1-024-34680-000 Pressure Switch

The York S1-024-34680-000 Pressure Switch is a critical safety component designed for precise draft inducer motor monitoring in specific York, Coleman, and Luxaire gas furnaces. This tri-level pressure switch features calibrated set points of .70/1.00/.40 PF and operates in a Normally Open (N/O) configuration. Engineered to detect vent pressure fluctuations, it ensures the combustion blower is operating within manufacturer flight specs before allowing the ignition sequence to proceed. When diagnosing furnace pressure switch stuck open faults or limit circuit errors, this OEM replacement provides the exact electrical resistance and pneumatic sensitivity required for HVAC system reliability and furnace safety compliance.

• Direct OEM Replacement: Ensures seamless mechanical fit and correct electrical termination for York S1-024-34680-000 specifications.
• Precise Calibration: Features factory-set trip points (.70", 1.00", and .40") to prevent nuisance tripping and maintain combustion efficiency.
• Durable Diaphragm Construction: Built to withstand high-cycling under varying thermal conditions within the furnace cabinet.
• Safety Assurance: Rapidly detects blocked vent pipes or failed inducer motors to prevent hazardous operation.

Common Questions

How do I troubleshoot a pressure switch error on a York furnace?
First, inspect the pressure switch tubing for cracks or moisture buildup. Verify the inducer motor is spinning at full RPM and that the venting system is free of obstructions before testing the switch for continuity using a multimeter during the startup cycle.

What does the N/O designation mean for this switch?
The Normally Open configuration means the internal contacts remain open until the draft inducer creates sufficient negative pressure to close the circuit, signaling the integrated furnace control board to continue the heat call.

Does this switch replace other York pressure switch part numbers?
While many switches look similar, the set points (.70/1.00/.40) must match exactly. Always verify the part number on the existing switch's label to ensure furnace compatibility and safe operation.
