Why is my LG ACHH017VBAB Chiller vibrating loudly?
- O
  ogilbertAug 13, 2025
  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.

What to do if the condensation pressure is high and my LG Chiller stops constantly?
- R
  Robert JonesAug 17, 2025
  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.

How to troubleshoot an LG ACHH017VBAB that does not start?
- Z
  zbenitezAug 20, 2025
  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.

What to do if my LG ACHH017VBAB's evaporation pressure is low and it constantly stops?
- R
  randymartinezAug 25, 2025
  If the evaporation pressure in your LG Chiller is low and the product constantly stops, it could be due to insufficient refrigerant. Check for any leakage and refill the refrigerant as needed. Another potential cause is insufficient cold water. Inspect the cold water system, ensuring the rated flow is maintained, the cold water system valve is open, the pressure difference between the inlet and outlet is appropriate, and there is no air in the cold water system.

Why my LG ACHH017VBAB is constantly hunting for cold water temperature?
- S
  Sarah EscobarAug 28, 2025
  If your LG Chiller is constantly hunting for cold water temperature, it may be due to insufficient cold water. Check the cold water system to ensure the rated flow is correct. Verify that the valve of the cold water system is open, the pressure difference between the inlet and outlet is appropriate, there is no air in the cold water system, and the cooling load is within the appropriate range.

How to fix resonance sound in LG ACHH017VBAB Chiller?
- K
  Kyle ChaseSep 1, 2025
  If you notice a resonance sound coming from your LG Chiller, the rubber fixed condition of the motor mount might be defective, requiring replacement of the motor mount. Alternatively, there could be a pipe vibration defect around the compressor, in which case you should replace the anti-vibration rubber attached to the pipe.

How to eliminate high frequency wave noise from the front of my LG Chiller?
- J
  John ParksSep 4, 2025
  If you are experiencing a high-frequency wave noise from the front side of your LG Chiller, it may be due to a defect in the heat emitting fan in the control box. Try cleaning the area around the heat emitting fan.

Why is the evaporation pressure high in my LG Chiller?
- C
  Carl WarrenSep 8, 2025
  If the evaporation pressure of your LG Chiller is high, it may be due to a temporary rise in cold water temperature caused by an abnormal increase in load. This is not necessarily abnormal, but you should check if it is within the operating range.
