Carrier 30GT515217 EXV Board

The Carrier 30GT515217 EXV Board is a high-precision, programmed electronic expansion valve board engineered for advanced refrigerant metering in commercial chillers. As a critical replacement for legacy part numbers HK50AA026 and BRD-3907, this genuine OEM Carrier part provides the exact logic required to modulate electronic expansion valves (EXV) based on real-time superheat data and refrigeration load. Operating on 50/60Hz single-phase power, the module ensures optimal cooling efficiency by maintaining precise evaporator temperatures, which is vital for protecting compressors from liquid slugging.

Designed for seamless integration with Carrier 30GTN and 30RAP Series chillers, this Factory Authorized Part eliminates the compatibility risks associated with generic alternatives. Its robust architecture is built to withstand the electrical demands of heavy-duty HVACR environments, providing reliable service life for Carrier, Bryant, and Payne equipment. This HVAC control board comes pre-programmed from the manufacturer, facilitating a straightforward "plug-and-play" installation for technicians looking to restore system integrity and precise refrigerant flow control in industrial applications.
