Moquet 860-654873B-01 power controller Repair Service

Professional diagnostic and board-level repair service for this Moquet 860-654873B-01 power controller.

Moquet 860‑654873B‑01 is a microprocessor‑controlled chiller control port circuit board used to regulate compressor speed and fan drives in HVAC chillers. Common failure points on this class of boards include burnt or tripped MOSFETs, degraded electrolytic capacitors, and damaged I/O connectors; the board’s firmware can also become corrupted during power interruptions. Begin diagnostics by verifying that the supply rails (±15 V, 24 V DC) are within spec, inspecting for visual signs of component damage or burn marks, and checking all input/output signals against the chiller’s data sheet. If no obvious hardware faults appear, review the controller’s diagnostic logs for error codes related to motor control or communication failures. Post Comment
