What to do when your Coovert room air conditioner won't start

Reset the circuit breaker on the power plug if the power cord has that component on your room air conditioner.

If your room air conditioner has electrical power--the control panel powers up--but the compressor and fans won't run, possible causes include an electronic control failure or a wiring problem.

The window air conditioner also won't start if the electronic control detects a component problem such as a defective thermistor. Check the control panel for an error code, which usually indicates which component failed. To decipher an error code, check our error code tables or refer to your owner's manual. Some repairs that could correct the problem are listed below.

Top replacement parts for Coovert room air conditioners

• User interface control board. The user interface control board is a circuit board with selection buttons and display components, which is mounted on the control panel of the air conditioner. The user interface control board sends signals to the electronic control board to communicate the window air conditioner’s settings.
• Thermistor. The thermistor is a temperature sensor in the window air conditioner that sends information to the electronic control board.
• 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.
• 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.
