York S1-025-42666-000 Control
The York S1-025-42666-000 Control, also identified by part number S1-ICM325A, is a high-performance, single-phase head pressure control designed for precise regulation in residential and commercial condensing units. Supporting a wide input range of 120-600V at 50/60Hz, this OEM-level component is built for reliability in varying environmental conditions. For service technicians, this unit serves as a critical condenser fan speed controller, modulating motor speed based on liquid line temperature or pressure to prevent compressor flooding and low-evaporator temperatures during low-ambient cooling operations. Its 1PH configuration ensures a direct fit for York HVAC replacement parts, helping maintain optimal head pressure and system efficiency. By eliminating the risk of excessive head pressure drops, this control stabilizes heat transfer across the coils, ensuring the refrigerant cycle remains within its engineered design parameters even when outside temperatures plummet. This is a rugged, field-proven solution for HVAC pressure switch upgrades and emergency repairs across the York, Luxaire, and Coleman product lines.
Key Benefits- Universal Voltage Integration: Compatible with 120V to 600V systems, offering maximum 1PH versatility for diverse equipment.
- Low-Ambient Stability: Prevents system short-cycling and evaporator freeze-ups by managing fan speeds in cold weather.
- OEM Precision: Direct replacement part ensures exact electrical specifications and mounting footprint for York and Johnson Controls units.
- Enhanced Efficiency: Extends component life by modulating motor torque rather than hard-starting on and off.
- Contractor Grade: Built to withstand the harsh electrical environments found in outdoor condensing sections.
Is the York S1-025-42666-000 a direct substitute for the S1-ICM325A?
Yes, the S1-025-42666-000 is cross-referenced as the S1-ICM325A. It is the official replacement for this voltage range and phase configuration.
What symptoms indicate this head pressure control has failed?
Typical failure signs include the condenser fan failing to start, the fan running at full speed regardless of temperature, or inconsistent compressor lockouts during low-ambient operation.
Does this control support 3-phase applications?
No, this specific part is engineered for 1PH (single-phase) motors only. Check your motor nameplate before installation to ensure compatibility.
