- MV4000 Main Controller Board
The Bard 8612-038 MV4000 Main Controller Board is the OEM control board used in Bard MV4000 Series dual-unit lead/lag controller systems, where one controller coordinates two Bard wall-mount air conditioners for automatic lead rotation, staging, and redundancy. This board provides the low-voltage control logic and terminal connections that manage fan and cooling/heating outputs for each unit, helping ensure dependable changeover and consistent operation in telecom shelters and other critical applications. If your MV4000 controller has failed outputs, erratic staging, or will not run one or both units correctly, replacing the 8612-038 with the correct Bard factory board is the right repair to restore proper sequence of operation and system reliability; confirm compatibility by matching your MV4000 model and the parts list in the Bard MV4000 manual before ordering.
