York S1-024-25329-705 Pressure Switch

The York S1-024-25329-705 is a high-precision 1.3" WC air pressure switch designed for critical safety monitoring in York, Coleman, and Luxaire gas furnaces. As an OEM HVAC replacement part, this SPNC (Single Pole Normally Closed) switch is engineered to monitor the negative pressure generated by the furnace inducer motor. Its Open On Rise functionality ensures that if the combustion air blower fails or the venting system becomes restricted, the heating cycle is immediately interrupted to prevent unsafe operation. For technicians in the field, this Source 1 pressure control offers a drop-in HVAC inducer safety switch solution that maintains the precise static pressure setpoints required by commercial and residential air handlers.

• Precise 1.3" WC Rating: Calibrated to meet exact factory specifications for accurate furnace pressure switch troubleshooting.
• Broad Compatibility: An official Source 1 OEM part compatible with various York furnace pressure switch models and associated brands.
• Enhanced Safety: The Open On Rise mechanism provides reliable circuit interruption during flue obstructions or mechanical inducer failure.
• Durable Construction: Built to withstand the high-temperature environments of gas-fired furnace compartments without drift in setpoint.

What does 'Open On Rise' mean for this part?
This indicates that the electrical contacts are normally closed and will move to the open position when the sensed pressure rises to the 1.3" WC threshold, effectively breaking the safety circuit.

Can I use a switch with a different WC rating?
No. For safety and performance, you must use a switch that matches the manufacturer-specified pressure rating, like this S1-024-25329-705, to ensure the inducer is moving the correct volume of air.

Does this switch work on both York and Coleman units?
Yes, because both brands utilize Source 1 service parts, this switch is a direct cross-reference for multiple 1.3" WC applications across those equipment lines.
