York 024-25509-000 Thermostat

Ensure terminal climate control and compressor safety with the York 024-25509-000 Oil Heater Thermostat. Engineered specifically for York Chiller systems and large-scale HVAC oil heater applications, this SPST switch is a critical component for regulating lubricant temperature. It features a fixed setpoint calibrated at 115 degrees F, preventing oil viscosity issues and ensuring the crankcase heater maintains optimal thermal conditions to prevent refrigerant migration during off-cycles. This OEM York replacement part provides the precise on-off temperature control required to protect expensive compressor rotors and bearings from cold-start wear.

The York 024-25509-000 is built for industrial-grade durability, handling the high-vibration environments typical of commercial chiller operations. Integrating this oil heater thermostat into your maintenance routine ensures that the crankcase heating system operates only when necessary, optimizing energy efficiency while upholding the mechanical integrity of the refrigeration circuit. For contractors performing HVAC troubleshooting, this direct replacement thermostat ensures a seamless fit and rapid restoration of system parameters without the need for field recalibration.

• Fixed Thermal Precision: Factory-set at 115°F (46°C) to maintain proper oil lubrication properties and compressor longevity.
• Reliable SPST Action: Simple Single-Pole Single-Throw mechanism provides dependable on-off temperature control for HVAC oil heaters.
• Direct OEM Compatibility: Specifically designed for York applied systems and rotary screw liquid chillers, ensuring perfect physical and electrical fitment.
• Industrial Durability: Robust construction capable of withstanding the demanding conditions of commercial cooling and heating systems.

What happens if the oil heater thermostat fails?
If the York 024-25509-000 fails in the open position, the oil heater will not activate, leading to low oil temperatures and potential compressor slugs. If it fails closed, the heater may run continuously, overheating the oil and degrading its lubricating properties.

Where is this thermostat typically installed?
This HVAC part is usually found mounted on or near the compressor crankcase or oil reservoir in York centrifugal or screw chillers to monitor oil temperature directly.

Can I use this for any oil heater application?
While it is an industrial-grade temperature control, it is optimized for systems requiring a 115°F setpoint. Always verify York OEM part numbers against your specific unit’s technical manual before installation.
