York S1-025-38948-000 Reversing Valve Coil

The York S1-025-38948-000 is a precision-engineered 24V Reversing Valve Coil designed for high-duty cycle performance in residential and light commercial heat pump systems. Built to the exact specifications of York, Luxaire, and Coleman equipment, this solenoid coil facilitates the critical transition between heating and cooling modes by providing the electromagnetic force necessary to actuate the 4-way reversing valve. Operating on a standard 24V AC control circuit, this component is a primary solution for technicians troubleshooting "stuck" systems or electrical failures within the reversing circuit. The coil features high-grade internal windings protected against thermal stress and moisture, common in outdoor condensing units. Its slide-on design allows for rapid field replacement on compatible valve stems, enabling HVAC contractors to restore system reversing functionality without the need for refrigerant recovery or system evacuation, provided the mechanical valve body remains operational.

Key Benefits

• Ensures precise 4-way valve actuation for reliable seasonal mode switching.
• Direct OEM replacement for S1-025-38948-000, eliminating fitment issues in York heat pumps.
• Heavy-duty lead wires and insulation designed for the high-vibration environment of HVAC condensers.

Common Questions

How do I verify if the coil has failed?
Use a multimeter to check for solenoid continuity and verify that the coil is receiving 24V AC from the defrost board or thermostat when the O/B terminal is energized.

Will this work with other brands besides York?
While primarily designed for Johnson Controls brands (York, Coleman, Luxaire), this 24V coil may fit other valves with the same stem diameter; however, verifying the specific S1-025-38948-000 part number is recommended for guaranteed compatibility.

Does this coil include the valve body?
No, this is the replacement solenoid coil only. If the internal slide mechanism of the reversing valve is mechanically seized, a full valve replacement will be required.
