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

IssuePossible Causes
Unit does not turn on when pressing ON/OFF buttonThe 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 modeThe 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 mistIn 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 mistWhen the unit restarts in HEAT mode after defrosting, white
mist may be emitted due to moisture generated from the
defrosting process
The indoor unit makes noisesA rushing air sound may occur when the louver resets its
position.
Both the indoor unit and outdoor unit make noisesSqueaking sound: Normal expansion and contraction of
plastic and metal parts caused by temperature changes during
operation can cause squeaking noises.
The outdoor unit makes noisesThe unit will make different sounds based on its current
operating mode.
Dust is emitted from either the indoor or outdoor unitThe 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
of inactivity.
The unit emits a bad odorThe unit may absorb odors from the environment (such as
furniture, cooking, cigarettes, etc.) which will be emitted
during operations.
The fan of the outdoor unit does not operateDuring operation, the fan speed is controlled to optimize
product operation.
Operation is erratic, unpredictable, or unit is unresponsiveInterference 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
