Top repair parts for Midea portable air conditioners

• Electronic control board. The electronic control board controls the major electro-mechanical components in the air conditioner. The electronic control board receives input from temperature sensors to monitor the temperatures inside the room and at the evaporator. With this information, the electronic control board manages the on/off cycling of the compressor to cool the room to the set temperature. The electronic control board activates the compressor and fans when it senses that the room temperature exceeds the set temperature.
• Compressor. The compressor receives low-pressure refrigerant gas from the evaporator and rotates to compress that refrigerant to a high-pressure gas that moves through the condenser. The refrigerant gets hot when compressed by the compressor pump. The condenser is a heat exchanger that removes heat from the refrigerant gas and condenses it into a high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows through the expansion device and into the evaporator that's at low pressure. The high-pressure refrigerant expands and evaporates. It absorbs the latent heat of vaporization as it changes from a liquid to a gas, which causes the cooling action in the evaporator. The refrigerant flows through the evaporator and back to the compressor where the cycles starts over.
• Evaporator fan. The evaporator fan is mounted behind the evaporator assembly. It moves air across the evaporator fins and into the room for cooling.
• Thermistor. The thermistor is a temperature sensor in the air conditioner that sends information to the electronic control board.

Midea portable air conditioner cleaning tips

Before cleaning, turn the portable air conditioner off and unplug the power cord.

Regularly clean the outer surfaces of the portable air conditioner with a damp cloth then dry the surfaces with a soft, dry cloth. For safety, never wash the air conditioner with water. Don't use petroleum products, alcohol or solvents to clean the air conditioner.

To keep your portable air conditioner running efficiently, clean the air filter weekly. Remove the air filter by pulling it upward. Use a vacuum cleaner to remove dust and dirt from the air filter. When it's very dirty, immerse the filter in warm water then rinse it under tap water thoroughly. Let the filter air dry completely before reinstalling it in the air conditioner.
