Why is my Midea Air Conditioner not cooling or heating at all?
- O
  oclarkAug 18, 2025
  If your Midea Air Conditioner is not cooling or heating, check the voltage and call an electrician if it's not within the limit. Inspect the terminals and repair or correct any loose connections. Check and adjust the thermostat and main switch settings. Inspect the resistance of the reverse valve wire and replace it if it's shorted, open, or damaged. If the reverse valve is blocked, which prevents heating, replace it after checking the reason.

Why is my Midea Air Conditioner fan motor so noisy?
- D
  Dana FranklinAug 22, 2025
  If your Midea Air Conditioner fan motor is noisy, replace the fan or blower if it's cracked, out of balance, or partially missing. Tighten any loose screws. If knocking sounds persist or the motor hums, replace the motor due to worn bearings.

Why does my Midea MWF-09CM start and stop frequently?
- R
  rodriguezbrandonAug 26, 2025
  If your Midea Air Conditioner unit starts and stops frequently, the input power supply voltage may be too low; consult an electrician if it's not within limits. Alternatively, the compressor may be protecting itself because the outdoor temperature is too high.

What to do if Midea MWF-09CM compressor will not run but fan motor runs?

  jeffreynguyenAug 28, 2025
  If your Midea Air Conditioner compressor won't run while the fan motor does, check the voltage and call the Supply Authority if it's not within limits. Inspect the wire connections; repair or replace any loose terminals, and refer to the wiring diagram to correct any misplaced wires. Replace the main switch if it has failed. Check the capacitor and replace it if it's not within +/-10% of the manufacturer's rating or if it's shorted, open, or damaged. Ensure the thermostat is set to the coolest setting for cooling mode or the warmest for heating mode. Check the compressor for an open circuit or ground; replace it if found.

How to fix Midea MWF-09CM Air Conditioner fan motor that will not run?
- J
  jessicacruzAug 31, 2025
  If your Midea Air Conditioner fan motor won't run, first check the voltage at the electrical outlet and correct it if there's no power. Then, check the voltage at the power cord terminal and replace the power cord if there's no voltage. Inspect for disconnected or loose wires, connecting them according to the wiring diagram and repairing or replacing any loose terminals. If the main switch has failed, replace it. Test the capacitor (after discharging it) and replace it if it's not within +/-10% of the manufacturer's rating or if it's shorted, open, or damaged. Finally, realign the assembly if the fan blade is hitting the shroud or the blower is hitting the scroll, and check the fan motor bearings; replace the motor if the shaft doesn't rotate.

What to do if Midea Air Conditioner stops instantly after startup?
- M
  masseybrookeSep 4, 2025
  If your Midea Air Conditioner stops instantly after startup, it could be due to too much refrigerant, causing the compressor to overload. Recycle and recharge the refrigerant after identifying the cause. Alternatively, the compressor may be seized, requiring replacement after checking the reason.

Why Midea MWF-09CM fan motor runs intermittently?
- L
  latoya99Sep 7, 2025
  If your Midea Air Conditioner fan motor is running intermittently, check the voltage and consult an electrician if it's not within the correct limits. Test the capacitor and replace it if it's not within +/-10% of the manufacturer's rating. Check the bearings and replace the motor if the fan blade doesn't rotate freely. Also, observe any changes from high to low speed; replace the motor if the speed doesn't change.

  Joseph SmithSep 12, 2025
  If the compressor of your Midea Air Conditioner does not stop even when the room temperature reaches the setting temperature, check the thermostat and replace it if it is damaged.
