Why MAYEKAWA 8M motor does not operate?
- J
  Jennifer FuentesAug 23, 2025
  If your MAYEKAWA Air Compressor motor isn't operating, it could be due to several reasons. It may be a motor failure, in this case you should inspect and repair or replace the motor. Alternatively, the belt tension might be too high (adjust the tension). It is also possible that the voltage is dropped. Another cause could be failure of the cylinder sleeve, piston, ring, or metal part (inspect and repair or replace). Finally, there might be a failure or mistake in automatic control or electrical connections (inspect and repair).

  If the head cover of your MAYEKAWA Air Compressor is overheated, accompanied by high discharge and suction pressure, it could be because the compression ratio has increased due to increased condensed temperature or refrigerant load. Increase cooling water for the condenser, or higher the cooling water temperature.

  If the cooling water temperature of your MAYEKAWA Air Compressor's evaporative condenser is warm, it could be due to fan failure or clogged spray nozzle and strainer. Inspect, repair, and clean the affected components.

  If your MAYEKAWA Air Compressor motor does not operate, there could be several reasons. It could be due to motor failure, in which case you should inspect and repair or replace the motor. The belt tension might be too high, requiring adjustment. A voltage drop could also be the cause. If, upon removing the belt and rotating the pulley by hand, the pulley still doesn't rotate, there may be a failure of the cylinder sleeve, piston, ring, or metal part (shaft seal component), requiring inspection and repair or replacement. Lastly, there might be a failure or mistake in the automatic control and electric related connections (single phase), which would need inspection and repair.

  If the head cover of your MAYEKAWA Air Compressor is overheated, it may be due to insufficient cooling water distribution or a dirty cooling pipe. Distribute water evenly, or clean the cooling pipe.

  William GonzalezAug 31, 2025
  If there's no response when pressing the magnet switch button on your MAYEKAWA Air Compressor, check if the breakers have tripped and replace them if needed. Also, inspect and replace the magnet switch contact if it has failed, or if the protection switch is being pressed. Inspect and replace any electric wires that are cut off. Finally, ensure the OP (low oil pressure failure protection equipment) or HP (high pressure protection equipment) is reset (restored).

Why is my MAYEKAWA 8M Air Compressor condenser temperature warmer than usual?
- C
  Casey ZimmermanAug 29, 2025
  If the condenser temperature of your MAYEKAWA Air Compressor is warmer than usual, it could be due to a cooling water shortage or excessively high cooling water temperature. Increase the volume of cooling water, or lower the cooling water temperature.

What to do if MAYEKAWA Air Compressor energized when the magnet switch button is pressed, but turns off when released?
- D
  Dr. David PerryAug 28, 2025
  If your MAYEKAWA Air Compressor energizes when the magnet switch button is pressed but turns off when released, there may be a mistake in the automatic control related connections (inspect and repair). Another possible cause is a contact defect of the auxiliary contact or equivalent (inspect and repair or replace).

  Dustin Ray Jr.Aug 27, 2025
  If the condenser temperature of your MAYEKAWA Air Compressor is warmer than usual, it may be due to a cooling water shortage or excessively high cooling water temperature. To resolve this, increase the volume of cooling water or lower the cooling water temperature.

  If there's no response when you press the magnet switch button on your MAYEKAWA Air Compressor, it could be due to tripped breakers (inspect and replace). It may also be caused by a failure of the magnet switch contact, a pressed protection switch (inspect and repair or replace), cut electric wires (inspect and repair or replace), or the OP/HP being activated and not reset (restore).
