Mazak KMV-150-M15-G Chiller Unit

The Mazak KMV‑150‑M15‑G is a chiller control board used to regulate coolant temperature and flow in Mazak machine tools. Common failure points for this class of industrial electronic boards include degraded power supply filtering, burnt capacitors or solder joints on the main controller IC, and overheating of the cooling fan or heat sink. Initial troubleshooting should verify that the 24 V DC input is within spec, inspect the board for visual signs of component damage (burn marks, bulging caps), and check the status LEDs or error codes displayed on the unit’s panel. If no faults are apparent, perform a continuity test across the fan driver circuit and measure the output voltage to the coolant pump to ensure proper signal transmission.[oss-gpt-20b]
