Top replacement parts for Frigidaire window air conditioners

• Electronic control board. The electronic control board controls the major electro-mechanical components in the window 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.
• Condenser fan. The condenser fan moves air across the condenser to enhance the cooling process of the hot, compressed refrigerant that flows through the condenser.
• Refrigerant. Refrigerant is the fluid—such as Freon—that flows through the compressor and sealed system of the window air conditioner. The refrigerant enters the compressor and is compressed to a hot, high-pressure gas. The hot refrigerant gas then flows through the condenser where it cools and condenses to a liquid before entering the low-pressure evaporator. When the refrigerant enters the low-pressure environment of the evaporator, the liquid refrigerant evaporates to a vapor. The evaporating refrigerant absorbs the heat from the air that blows across the metal fins in the evaporator. The air cools as it blows across the metal fins of the evaporator.
• Thermistor. The thermistor is a temperature sensor in the window air conditioner that sends information to the electronic control board.

What to do when evaporator fins ice up on your Frigidaire window air conditioner

See the repairs below to help correct a problem with evaporator finds that ice up.
