  If your LG Chiller vibrates loudly, several issues could be the cause. Start by checking if the fan-motor connecting bolt, motor-mount assembly, compressor assembly bolt, or frame assembly bolt are loose and tighten them if needed. Also, inspect the fan for balance and replace it if necessary, checking its rotation range beforehand. Finally, listen for abnormal noise from the motor (a noise in multiples of RPM) which could indicate a burnt motor bearing, requiring motor replacement.

  If your LG Chiller's condensation pressure is high and it constantly stops, first check if the outdoor temperature is within the operating range. If the temperature is acceptable, inspect the condenser for accumulated particles and clean it if necessary. Finally, check the fan for any defects and replace it if needed.

  If your LG Chiller does not start, begin by checking the power supply to the device, including the over-current protection device and fuse. Ensure the device configuration and wiring are correct. Also, check for any active alarms and follow the alarm troubleshooting process, referring to the HMI input channel for alarm condition input. Finally, verify whether the compressor has entered a start delay time.
