York S1-024-35592-000 Control

The York S1-024-35592-000 Control is a critical low ambient head pressure control designed to maintain stable system performance when outdoor temperatures drop. For technicians servicing commercial RTUs and split systems, this OEM York replacement part is essential for preventing compressor slugging and evaporator freeze-ups by varying the condenser fan speed. By regulating the head pressure based on liquid line temperature or pressure inputs, this controller ensures the refrigeration cycle remains within OEM specifications, even in extreme cold-weather cooling applications.

Built for high-demand environments, the S1-024-35592-000 facilitates reliable low ambient operation by preventing the sharp drops in discharge pressure that lead to oil migration and mechanical failure. This robust pressure control head integrates seamlessly with Johnson Controls and York legacy equipment, offering a direct-fit solution for maintaining HVAC system efficiency. Its solid-state design provides accurate response times, essential for protecting condenser fan motors and sensitive compressor internals during off-season cooling cycles.

• Ensures consistent mechanical cooling performance in ambient temperatures below 55°F.
• Protects the compressor by preventing liquid refrigerant floodback and ensuring proper lubrication.
• Optimizes head pressure to maintain evaporator coil temperatures and prevent icing.
• Direct OEM replacement ensures compatibility with York and Source 1 inventory systems.
• Reduces condenser fan noise and energy consumption during low-load conditions.

How do I troubleshoot a system that trips on high pressure with this control?
Verify that the low ambient control is modulating the fan correctly. If the fan fails to ramp up as discharge pressure rises, check the sensor placement on the liquid line or the SEC board configuration settings for potential communication errors.

Can this control be used with any condenser fan motor?
This York S1-024-35592-000 is typically rated for specific ball bearing motors capable of speed modulation. Always verify that the motor is rated for use with solid-state speed controllers to avoid overheating the windings.

What symptom indicates this pressure control has failed?
Failures often manifest as the condenser fan running at full speed regardless of temperature, or not running at all, leading to rapid refrigerant pressure spikes and high-pressure limit trips.
