If your Midea Air Conditioner sends air out but doesn't cool, the setting temperature might be improper. Ensure the setting temperature is lower than the room's during cooling or higher during heating. Also, the compressor might be under a 3-minute protection cycle; wait for 3 minutes and check again.
What to do if my Midea MTA1-76HR is not turning on?
Your Midea Air Conditioner may not be running due to a power supply failure. Operate it after the power supply resumes and ensure it's properly connected. Also, check if the power switch is connected. Replace the fuse if it's blown, and check for electric leakage. Finally, check the remote controller or wired controller for any issues.
How to improve the cooling effect of my Midea Air Conditioner?
The cooling effect of your Midea Air Conditioner might be poor because the condenser or evaporator is too dirty. Clean the heat exchanger to resolve this. Also, check if the filter is blocked and clean it if necessary. Ensure that the intake and exhaust orifices of both the indoor and outdoor units are not blocked. Remove any obstructions to maintain proper ventilation. Close all windows and doors, obstruct sunlight with curtains, and reduce heat sources in the room. It's also possible that the outdoor temperature is too high, which can deteriorate cooling performance. Finally, check for refrigerant leaks and replenish if needed.
Why is the cooling effect of my Midea MTA1-76HR Air Conditioner so poor?
The cooling effect of your Midea Air Conditioner may be poor due to excessive or deficient refrigerant. Detect any leaks and fill the refrigerant to the correct quantity. Air or non-condensable gas in the refrigerant loop can also cause this; make a vacuum again and refill the refrigerant. If the compressor fails, repair or replace it. Voltage that is too high or too low can also affect performance; install a voltage regulator to correct this. Finally, check for obstructions in the refrigerant loop; locate the cause and replace the affected part.
Why is the heating effect of my Midea MTA1-76HR Air Conditioner poor?
The heating effect of your Midea Air Conditioner might be poor because the outdoor temperature is lower than -7°C. In this case, use a heating device as the unit cannot operate normally. Ensure the doors and windows are closed tightly. If the refrigerant has leaked or is deficient, detect the leak and refill the refrigerant to the correct quantity.
Why doesn't the temperature indicator light up on my Midea MTA1-76HR?
The temperature indicator on your Midea Air Conditioner won't light up if the mode marked on the screen is FAN. In fan mode, the temperature cannot be set.
Why does the display disappear on my Midea Air Conditioner?
The display on your Midea Air Conditioner might disappear because the time set on the timer has expired, causing the air conditioner to stop running. Alternatively, if the timer is set to start the air conditioner, the display will disappear once the operation begins automatically.
