York S1-024-25006-708 Pressure Switch

The York S1-024-25006-708 Pressure Switch is a critical safety component designed for specific York, Coleman, and Luxaire gas-fired furnaces. This single-pole single-throw (SPST) switch is factory-calibrated to a 1.20" WC setpoint, ensuring the inducer motor maintains optimal static pressure before allowing the ignition sequence to proceed. Engineered for precision, it features a 1/4" barbed hose connection for secure pneumatic coupling and standard 1/4" male spade terminals for seamless integration into the existing wiring harness. As an OEM furnace pressure switch, this unit serves as a direct replacement for failing diaphragm sensors that cause intermittent "limit circuit open" codes or ignition failure. When diagnosing HVAC pressure switch troubleshooting issues, verify that the venting is clear and the heat exchanger is intact, as this York replacement part is built to high tolerances to prevent operation under unsafe combustion conditions.

• Precise 1.20" WC Calibration: Ensures accurate flue gas pressure detection to prevent rollout or incomplete combustion.
• OEM Compatibility: Genuine York S1-024-25006-708 part ensures exact fitment and electrical specifications for residential furnace models.
• Durable Diaphragm Construction: Designed to withstand high-cycle operation and temperature fluctuations within the burner cabinet.
• Standardized Connections: Features a 1/4" barbed connection and spade terminals for fast, professional installation.

How do I know if my York pressure switch is bad?
If the furnace inducer motor runs but the igniter fails to glow, check for a "3-flash" or similar error code indicating a pressure switch stuck open. Use a manometer to verify the system is pulling more than 1.20" WC; if it is and the SPST pressure switch fails to close, the internal diaphragm or contacts have likely failed.

Can I use a switch with a different WC rating?
No. Using a switch with a lower or higher "WC rating will compromise safety or lead to nuisance tripping. Always match the 1.20" WC specification found on the S1-024-25006-708 for proper combustion air validation.

Does this switch handle high voltage?
This is a pilot duty safety switch designed for 24V control circuits. It should never be wired directly to line voltage components.
