What to do if my mycom i160S Air Compressor stops immediately after startup?
- R
  Robert FrancoAug 15, 2025
  If your mycom Air Compressor stops immediately after starting, it could be due to the activation of the low pressure protection circuit. To resolve this, check for refrigerant leaks, stop any leaks found, and then add refrigerant. Also, be aware of potential moisture entering the system. Alternatively, the issue might stem from a malfunctioning low pressure protection switch, pressure sensor, or relay. Identify any defective devices, investigate the cause of the failure, take necessary actions, and replace the failed device.

How to troubleshoot a mycom Compressor that does not start up?
- B
  Belinda McfarlandAug 21, 2025
  If your mycom Compressor isn't starting, several factors could be at play. First, ensure the power source is active; use a checklist to confirm post-inspection actions. A main motor failure could also be the cause, so consult the motor's instruction manual for detailed troubleshooting. Check that the cooling water is circulating correctly, and if not, identify and replace any defective devices. A clogged circulation route can also prevent startup, so clear any blockages. Additionally, a faulty magnet, relay, or other component in the startup circuit may be the culprit, requiring replacement. Finally, a poor installation environment can hinder performance; improve temperature, humidity, and ventilation, and replace any defective ventilation fans.

  If the mycom Compressor stops immediately after starting, it could be due to the low pressure protection circuit activating. To fix this, check for refrigerant leaks, stop any leaks, and then add more refrigerant. Also, be mindful of moisture entering the system. Alternatively, the issue might stem from a failure in the low pressure protection switch, pressure sensor, or relay. In this case, identify the defective device, investigate the cause of failure, take necessary actions, and then replace the failed device.

Why does my mycom Compressor generate abnormal vibration and/or sound?
- D
  davidsmithAug 30, 2025
  If your mycom Compressor is generating abnormal vibration or sound, one potential cause is excessive vibration of the motor shaft. If other causes are ruled out, consider overhauling the compressor at a facility equipped for dynamic balance measurement and adjustment. Another cause could be liquid flow-back during startup, which often presents with a loud, abnormal noise; identify and address the root cause, then overhaul and inspect the compressor. Liquid flow-back during operation, indicated by notable frosting on the suction side, can also cause these issues. To prevent this, avoid rapid changes in heat load that exceed the set value of the heat exchanger and expansion valve.

What to do if there is a leak from the mechanical seal of my mycom Compressor?
- C
  Crystal WadeSep 2, 2025
  If you notice a leak from the mechanical seal of your mycom Compressor, it could be due to an initial leak after replacement, which should decrease gradually as the sliding faces settle. Ensure the leak doesn't increase continuously. The duration of this initial leak is approximately 200 hours. Alternatively, the sliding surface may be roughened due to overheating. In this case, review the operating conditions to reduce the frequency of starting and stopping the equipment. Finally, deteriorated parts can also cause leaks; replace them as needed, referring to causes and actions for "Overheating of sliding surface."

What causes capacity control malfunction in my mycom Compressor?
- B
  barbaramonroeSep 8, 2025
  If the capacity control is malfunctioning on your mycom Compressor, it could be due to a failure of the capacity control solenoid valve or related relays. If these parts are deteriorated, replace them. If water leakage is the cause, remove the source of the leak and replace any defective parts. Internal leakage of the capacity control solenoid valve can also cause issues, requiring replacement of the valve. Lastly, a defective capacity control oil supply line can lead to malfunction; remove the cause of the defect, and check the oil for contamination, replacing it if necessary.

What causes damaged thrust bearings in my mycom Compressor?
- K
  Kim MarquezSep 12, 2025
  If your mycom Compressor has damaged thrust bearings, one potential cause is excessive thrust stress due to high suction pressure exceeding the level set by operating conditions. Re-examine the operating conditions and improve them if possible. If improvement is difficult, review the maintenance interval management. Another cause could be faulty assembly, such as lock nuts tightened insufficiently, lock washer tab not bended, rotation stopper not set to thrust bearing gland, or spring washer not assembled. Tighten lock nuts to the specified torque or torque angle and record data on the assembly check sheet to prevent omission of work steps.
