This tutorial, we will listed down the full list of Midea AC error codes but before that, we would like to share some common issues of Midea AC. The following problems are not a malfunction and in most situations will not require repairs.
Midea AC common issues and possible causes
|Unit does not turn on when pressing ON/OFF button||The Unit has a 3-minute protection feature that prevents the unit from overloading. The unit cannot be restarted within three minutes of being turned off.|
|The unit changes from COOL/HEAT mode to FAN mode||The unit may change its setting to prevent frost from forming|
on the unit. Once the temperature increases, the unit will start
operating in the previously selected mode again.
|The indoor unit emits white mist||In humid regions, a large temperature difference between the|
room’s air and the conditioned air can cause white mist.
|Both the indoor and outdoor units emit white mist||When the unit restarts in HEAT mode after defrosting, white|
mist may be emitted due to moisture generated from the
|The indoor unit makes noises||A rushing air sound may occur when the louver resets its|
|Both the indoor unit and outdoor unit make noises||Squeaking sound: Normal expansion and contraction of|
plastic and metal parts caused by temperature changes during
operation can cause squeaking noises.
|The outdoor unit makes noises||The unit will make different sounds based on its current|
|Dust is emitted from either the indoor or outdoor unit||The unit may accumulate dust during extended periods of|
non-use, which will be emitted when the unit is turned on.
This can be mitigated by covering the unit during long periods
|The unit emits a bad odor||The unit may absorb odors from the environment (such as|
furniture, cooking, cigarettes, etc.) which will be emitted
|The fan of the outdoor unit does not operate||During operation, the fan speed is controlled to optimize|
|Operation is erratic, unpredictable, or unit is unresponsive||Interference from cell phone towers and remote boosters may|
cause the unit to malfunction. In this case, try the following:
• Disconnect the power, then reconnect.
• Press ON/OFF button on remote control to restart operation
How to check midea ac error codes?
If the indicator lamps continue to flash or error codes appear, wait for about 10 minutes. The problem may resolve itself. If not, disconnect the power, then connect it again. Turn the unit on.
If the problem persists, disconnect the power and contact your nearest customer service center.

Midea aircon troubleshooting
When troubles occur, please check the following points before contacting aircon servicing companies. If your problem persists after performing the checks and diagnostics below, turn off your midea ac unit immediately and contact an authorized service center.
Poor Cooling Performance
|Temperature setting may be higher than ambient room temperature||Lower the temperature setting|
|The heat exchanger on the indoor or outdoor unit is dirty||Clean the affected heat exchanger|
|The air filter is dirty||Remove the filter and clean it according to instructions|
|The air inlet or outlet of either unit is blocked||Turn the unit off, remove the obstruction and turn it back on|
|Doors and windows are open||Make sure that all doors and windows are closed while|
operating the unit
|Excessive heat is generated by sunlight||Close windows and curtains during periods of high heat or bright sunshine|
|Too many sources of heat in the room (people, computers, electronics, etc.)||Reduce amount of heat sources|
|Low refrigerant due to leak or long-term use||Check for leaks, re-seal if necessary and top off refrigerant|
|SILENCE function is activated||SILENCE function can lower product performance by reducing|
operating frequency. Turn off SILENCE function
The unit is not working
|Power failure||Wait for the power to be restored|
|The power is turned off||Turn on the power|
|The fuse is burned out||Replace the fuse|
|Remote control batteries are dead||Replace batteries|
|The Unit’s 3-minute protection has been activated||Wait three minutes after restarting the unit|
|Timer is activated||Turn timer off|
The unit starts and stops frequently
|There’s too much or too little refrigerant in the system||Check for leaks and recharge the system with refrigerant.|
|Incompressible gas or moisture has entered the system||Evacuate and recharge the system with refrigerant|
|The compressor is broken||Replace the compressor|
|The voltage is too high or too low||Install a manostat to regulate the voltage|
If ANY of the following conditions occurs, turn off your unit immediately!
- The power cord is damaged or abnormally warm
- You smell a burning odor
- The unit emits loud or abnormal sounds
- A power fuse blows or the circuit breaker frequently trips
- Water or other objects fall into or out of the unit
