Why is my Midea MPK2-09CRN1-QB6 Air Conditioner not cooling or heating?
- M
  madisonmorenoAug 19, 2025
  If your Midea Air Conditioner isn't cooling or heating, begin by checking the voltage. Verify the wiring terminals are secure, repairing them if loose. Ensure the temperature and mode settings are correctly adjusted. Inspect the compressor, overload protector, and wiring for any damage, replacing if necessary. If the unit uses an electric heater, check for damage and replace if needed. Also, examine the overheat fuse and replace if it's damaged. Finally, check the voltage of the main PCB; if the unit fails in heating mode, replace the main PCB.

How to fix no power display on panel of Midea MPK2-09CRN1-QB6 Air Conditioner?
- C
  Cheryl RyanAug 22, 2025
  If there is no power display on the panel or button failure on your Midea Air Conditioner, check the power supply to ensure it's providing power to the unit. Inspect the power cord for damage and correct if necessary. Check the resistance between the input/output lines on the transformer (discharge transformer before testing), and replace the transformer if either input/output is open or the transformer is damaged. Check the voltage on the display board, replace the display board if it is +5V else replace the main PCB.

What to do if Midea MPK2-09CRN1-QB6 shows water full alarm?
- J
  Jennifer ThomasAug 26, 2025
  If you're getting a water full alarm on your Midea Air Conditioner, start by checking if the water tank is full and empty it if necessary. Inspect the water depth sensor and replace it if it has failed. Check the water pump and replace it if it's not working. If the water depth is overloaded in the chassis, drain the water by opening the drainage hose. Finally, inspect the water depth sensing structure and replace or realign it if it's faulty.

How to fix Midea MPK2-09CRN1-QB6 Air Conditioner fan motor noise?
- M
  mark33Aug 28, 2025
  If your Midea Air Conditioner's fan motor is making noise, the fan blower might be cracked, out of balance, or partially missing; replace it if any of these issues are present. Check for any loose screws and tighten them. If knocking sounds continue when the motor is running, or if the motor hums or the noise appears internal, the bearings may be worn; replace the motor in this case.

What to do if compressor will not run while fan motor runs in Midea Air Conditioner?
- S
  Stephanie LambertAug 31, 2025
  If the fan motor runs but the compressor won't start on your Midea Air Conditioner, start by checking the voltage. Inspect the wire connections and repair or replace any loose terminals. If wires are off, refer to the wiring diagram for proper placement. Check the voltage of the main PCB and replace it if open. Examine 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 room temperature setting is at the coolest setting in cooling mode or the warmest in heating mode. Finally, check the compressor for open circuits or grounding, and replace the compressor if necessary.

Why does my Midea MPK2-09CRN1-QB6 unit start and stop frequently?
- M
  michelle12Sep 6, 2025
  If your Midea Air Conditioner starts and stops frequently, the input power supply voltage may be too low. Check the voltage and call an electrician if it's not within limits. Inspect the main PCB and replace it if the compressor relay on the PCB is shorted or damaged. Also, when the room temperature is too high, the compressor will protect itself.

Why does Midea MPK2-09CRN1-QB6 compressor stop instantly after startup?
- M
  myoungSep 9, 2025
  If the compressor on your Midea Air Conditioner stops instantly after startup, it could be due to too much refrigerant, causing the compressor load to be too high. Recycle and recharge the refrigerant after checking for the reason. Alternatively, the compressor might be blocked internally; replace it after investigating the cause.

Why does Midea Air Conditioner fan motor run intermittently?
- J
  Jeremy HowardSep 12, 2025
  If the fan motor on your Midea Air Conditioner runs intermittently, it may be cycling on overload. Check the voltage, and if it's not within limits, call an electrician. Test the capacitor and replace it if it's not within +/-10% of the manufacturer's rating. Check the bearings; if the blower wheel cannot rotate freely, replace the motor. If the speed does not change from high speed to low speed, replace the motor.
