York 371-02757-003 Power Control Board

1. Advantage：

This YORK power control board (P/N 371-02757-003) is a large-format power stage board mounted on a rigid metal backplate. It carries a row of toroidal inductors, high-power orange components, a finned heat sink, and extensive drive circuitry-all the elements of a chiller power board that switches and conditions power to compressors or fans. The metal backplate provides both mechanical mounting and heat sinking, making this a heavy-duty assembly built for continuous industrial operation.

3.Our Advantage

Large power boards like this are expensive and ship at higher freight cost-getting the wrong one is a costly mistake. We confirm the board's part number against your chiller model and serial before dispatch. These boards fail under high-load conditions (compressor startup, voltage spikes), so if your chiller trips on overcurrent or refuses to start, this power board is a likely suspect. Send us your fault code and we will help confirm.
