This 115v ECM motor requires specific pulse-width modulation (PWM) or speed tap signals from the furnace control board

Failure is typically caused by excessive carbon deposits

maintaining the OEM circuit resistance specifications required for precise timing and consistent burner ignition

this valve is engineered to handle the higher operating pressures associated with R-410A and is also compatible with R-22 systems provided the 3/4" line size matches

providing a direct fit for 4-ton cooling cycles in residential and light commercial applications

York 025-40273-008 Sensor R-134A This 115v ECM motor requiresThe York 025 40273 008 Ambient Temperature Sensor is a critical thermistor based component engineered specifically for York YCAL Air Cooled Scroll Chillers. This NTC (Negative Temperature Coefficient) sensor provides high precision resistance feedback to the Millennium or OptiView control centers, allowing for accurate staging and head pressure management based on outdoor ambient conditions. As a direct OEM replacement part, it ensures the control
