York S1-024-39713-000 Pressure Switch

The York S1-024-39713-000 Pressure Switch is a critical safety component designed for precise monitoring of combustion air and exhaust venting in high-efficiency HVAC systems. This 1.10 WC pressure switch ensures that the inducer motor is moving sufficient air to safely vent combustion gases before the ignition sequence initiates. As the direct S1-024-35777-000 replacement, this OEM part maintains the specific factory-spec calibration required for modern gas-fired furnaces. For contractors troubleshooting a York inducer motor pressure switch error, this SPST switch provides the electrical reliability needed to prevent nuisance tripping and common pressure switch stuck open codes. Engineered for durability in high-cycle environments, the S1-024-39713-000 features a rugged construction that integrates seamlessly with existing control board logic. When a furnace pressure switch troubleshooting process identifies a failed internal diaphragm or oxidized contacts, swapping in this properly calibrated assembly is the professional standard for restoring heating system operation and safety integrity across various York, Coleman, and Luxaire units.

Common Questions

What is the specific set point for the York S1-024-39713-000?
This switch is calibrated to trigger at 1.10 inches WC, making it essential for specific high-efficiency furnace models that require high static pressure for safe operation.

Is this compatible with the legacy S1-024-35777-000 switch?
Yes, this part is the manufacturer-designated direct replacement for the older S1-024-35777-000 model and meets all original performance requirements.

How do I know if this pressure switch is the cause of a furnace failure?
Indicators include the inducer motor running without ignition or receiving a 3-flash error code; always verify the 1.10 inch WC set point matches the data plate and test with a manometer before replacement.
