If the air conditioner is used for a long time and is not maintained regularly, the cooling effect suddenly drops, which may be the leakage of refrigerant. If the refrigerant leaks, you need to contact professional maintenance personnel for on-site maintenance. Because it is necessary to vacuum the refrigerant and ensure that the internal pressure of the air conditioner is within the standard range, it is recommended to find professionals without maintenance experience. 2. If it is found that the fan of the external air conditioner does not work, it may be caused by the operation failure of the compressor inside the external air conditioner. You can check whether the starting capacitor of the compressor is faulty first. If there is a fault, you can replace a compressor starting capacitor and then check whether it can start normally.
