York S1-025-38888-001 Control
The York S1-025-38888-001 High Pressure Switch is an essential safety component designed for commercial HVAC systems and residential split units utilizing R-410A refrigerant. This encapsulated pressure control is engineered for high-side protection, featuring a 650 PSI open and 450 PSI close setpoint to prevent compressor damage during high-head pressure events. As a direct OEM York replacement part, it ensures precise calibration and reliable cycling, maintaining system integrity under demanding peak-load conditions. The SPST auto-reset configuration allows for seamless integration into existing control boards, providing a ruggedized solution for high pressure cutout requirements. Technicians should prioritize this Johnson Controls manufactured part to maintain factory specifications and ensure proper refrigerant pressure monitoring within the cooling circuit.
Key Benefits- Factory-Calibrated Precision: Features a fixed 650 PSI trip point and 450 PSI automatic reset for consistent system protection.
- Rugged Encapsulation: Built to withstand vibration and environmental moisture, preventing premature switch failure in outdoor condensers.
- Direct OEM Compatibility: Ensures proper thread fit and electrical termination for York, Luxaire, and Coleman equipment without field modification.
- Enhanced Safety Margin: Rapidly interrupts the contactor circuit to protect the compressor from thermal overload and mechanical stress.
What causes this switch to trip in high-efficiency systems?
Frequent tripping usually indicates a dirty condenser coil, a failing outdoor fan motor, or an overcharged system. If the switch opens at 650 PSI, verify subcooling levels to diagnose the root cause.
Can this pressure switch be used with refrigerants other than R-410A?
This control is specifically rated for the higher operating pressures of R-410A. Applying it to R-22 or low-pressure systems will result in improper cutout thresholds and potential equipment damage.
Is this an automatic or manual reset control?
The York S1-025-38888-001 is an automatic reset switch. Once head pressure drops below the 450 PSI differential setpoint, the internal contacts will close to resume cooling operations.
