#1 Air Conditioner is Not Turning On/Off After Restarting

This is a common and normal restart operation with your air conditioning unit. The Midea air conditioner has a 3-minute protection feature that prevents the unit from overloading after restarting. The unit cannot be restarted within three minutes of being turned off.

Alternatively, you may check your indoor or outdoor unit for any signs of excessive heat that is causing your air conditioner to overload. Cool down your unit before attempting to restart it to avoid overheating the air conditioner. For the outdoor unit, you may need to place a shade above the metal frame to protect it from the heat of the sun.

If your air conditioner is not powering on at all, check your power cord. The cord may have a loose connection, or may be unplugged. Secure the plug, and test to see if your air conditioning unit can function properly. Else, check the breaker box for any tripped circuit breakers, which may have set off during restarting. Flip the switch back to solve the issue.

#2 Air Conditioner Switches Between Cool Mode and Fan Mode

Air conditioners can frost up, and the AC unit may switch to fan mode to thaw out the frost that accumulated around the unit. This is a safety mechanism that protects the evaporator coils, compressor, and air filter from damage.

Because frost is often caused by a dirty air filter and coils, cleaning these components will minimize the frequency of air conditioners freezing up. You'll be able to enjoy unhindered cooling, while maintaining the good condition of your AC unit. However, cold temperatures outside may also cause frost, so it is best to avoid using the AC during cool weather.

Additionally, you may want to check your temperature settings. If your temperature setting is higher than the ambient room temperature, lower the temperature to keep your AC unit functional.

#3 Air Conditioner is Making Noise

If the indoor unit makes noises, identify the sound your air conditioner makes. Different noises indicate different issues, and determining the sound will help narrow down on the potential problems with your unit. A rattling noise may mean there is debris in your unit, while a whirring sound may be coming from the fan motor.

If both the indoor unit and outdoor unit make noises, check your compressor and capacitor. These components are at the heart of your air conditioner, which affects the performance of both indoor and outdoor units. Power off your air conditioner immediately, then contact our  technicians for aircon repair and replacements.

How to Reset Your Midea Air Conditioner

Reset Point: Circuit Breaker

To reset your Midea aircon, you will need to find the circuit that your AC unit is connected to. It is a good idea to unplug your other objects and devices from the same connection as you will be restarting the entire circuit.

Power off your air conditioning unit, then find the circuit it is connected to. Flip the switch, and wait 5-10 seconds before flipping the switch back into its original position. Power on your air conditioner to see if this does the trick. Most aircon issues can be resolved by a quick restart, but avoid regular restarting, especially if your circuit breaker trips frequently.

#1 Clean Your AC

More often than not, your AC unit is malfunctioning due to a dirty component, be it the filters, the air inlet and outlet vents, the coils, or other internal parts of your Midea AC unit. Cleaning these regularly will prevent most common aircon issues, and will solve most problems caused by an accumulation of dust and debris in your unit.

It is a good idea to schedule your cleaning session once every 4-6 months with a licensed technician at Luce Aircon. Our HVAC professionals will be able to deep clean your unit, leaving you with a fresh AC without any problems!
