Causes for your Sharp portable air conditioner running but not cooling

When your portable air conditioner's compressor and fans are running but the air conditioner isn't cooling, possible causes include a failed compressor or the lack of refrigerant due to a leak in the sealed system. If the compressor isn't running but the fans work, the start relay or compressor might have failed. A defective electronic control board or control thermostat could prevent the air conditioner from cooling.

Top repair parts for Sharp 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.
