How to fix over high air discharge pressure in Midea MGB-F60W/RN1 Chiller (Cooling operation)?

  Michelle WilliamsAug 20, 2025
  High air discharge pressure during cooling can stem from several issues. It could be due to air or non-condensing gas in the system, requiring you to discharge the gas and re-vacuum if needed. Dirty condenser fins or obstructions can also cause this, so clean the fins. Inspect the condenser fan for errors and ensure sufficient chilling air volume. Also, check if the ambient temperature is too high. Finally, if the refrigerant charging volume is excessive, discharge the extra refrigerant. If the air suction pressure is excessive high, refer to the section addressing that specific issue.

What to do if my Midea MGB-F60W/RN1 compressor stops because of motor Overload?

  If the compressor stops due to motor overload, the issue might be high air expelling and suction pressure (refer to those sections), voltage problems (ensure voltage isn't 20V above or below rated), a motor short circuit (check motor resistor connections), or an overload assembly error (replace the assembly).

What causes a Midea MGB-F60W/RN1 compressor to stop due to freeze-proof protection (Cooling operation)?
- M
  Mr. Joshua GonzalesAug 25, 2025
  The compressor might stop due to freeze-proof protection because of insufficient chilling water flow (check/repair the pump or flow control), gas in the water loop (discharge the air), or a thermal resistor error (replace it if confirmed).

What causes over low air suction pressure in Midea Chiller (Cooling operation)?

  Stephen Friedman Jr.Aug 27, 2025
  Low air suction pressure can occur due to several reasons: insufficient water flow (adjust flow based on temperature difference), low inlet chilled-water temperature (check installation), refrigerant leaks or insufficient refrigerant (find and repair leaks or recharge), or scaling in the evaporator (descale).

Why is the air suction pressure over high in my Midea MGB-F60W/RN1 Chiller (Cooling operation)?
- J
  Julia RochaAug 28, 2025
  High air suction pressure in cooling mode can result from overcharged refrigerant (discharge excess) or high inlet chilled-water temperature (check water pipeline insulation).

Why is the air suction pressure over high in my Midea Chiller (Heating operation)?
- K
  Kaitlyn ThomasAug 30, 2025
  Excessive air suction pressure during heating can be due to overheated air at the air heat exchanger (check ambient temperature) or overcharging of refrigerant (discharge the excess).

What causes a Midea MGB-F60W/RN1 Chiller compressor to stop due to Hi-pressure protection?
- E
  Eileen BarnesAug 31, 2025
  If the compressor stops because of high-pressure protection, it could be due to over high air expelling pressure (refer to that section) or a faulty high-pressure switch (replace if defective).

What causes a Midea MGB-F60W/RN1 Chiller compressor to stop because of Lo-pressure protection?
- R
  Robert JonesSep 4, 2025
  If the compressor stops due to low-pressure protection, it could be a blocked filter in front or rear of the expanding valve (replace the filter), a faulty low-voltage switch (replace it), or excessive low air suction pressure (refer to that section).

  Low air discharge pressure during cooling operation might be caused by a low surrounding temperature (measure the temperature) or a refrigerant leak or insufficient refrigerant (find the leak and recharge). If the suction pressure is low, refer to the “low suction pressure” section.
