When using the air conditioner, if the internal unit makes a strange buzzing sound, it may cause annoyance and discomfort. This buzz can stem from a variety of reasons, but don't worry, this article will provide you with a comprehensive solution.
Possible causes: The air conditioner filter has not been cleaned for a long time, and the accumulation of dust and impurities may cause the fan to hum.
Workaround:
Turn off the power of the air conditioner, turn on the air conditioner panel, and take out the filter.
Rinse the filter with a vacuum cleaner or clean water to make sure the filter is thoroughly dry before putting it back.
Possible cause: The fan propeller is affected by dust or foreign objects, which causes abnormal friction and humming.
Solution: Turn off the power of the air conditioner, open the air conditioner cover, and check whether there are foreign objects around the fan propeller. If there is a foreign object, clean it up with a small brush or vacuum cleaner.
Possible cause: Faulty or improper compressor may cause a humming sound in the air conditioner.
Solution: If you do not have relevant maintenance experience, it is recommended to contact professional technicians for inspection and repair.
Before servicing, make sure the power supply to the aircon has been completely disconnected.
Possible cause: The fan blades are displaced due to prolonged use, causing friction with other parts to produce a humming sound.
Solution: Open the air conditioner panel and observe whether the position of the fan blades is normal.
If you notice that the blades are offset, carefully adjust the position of the blades to ensure that they are installed correctly.
Possible causes: The air conditioner is not installed firmly or the hanger is loose, which may cause a humming sound.
Solution: Use rubber pads between the air conditioner and the hanger to insulate the sound and reduce the vibration and noise.
Make sure the installation is secure and reduces unnecessary shaking.

Solution: Turn off the power of the air conditioner and check whether the air duct connection is tight.
Clean the air duct to ensure good air circulation.

Solution: If you have maintenance experience, you can try lubricating the motor bearing.
If you are unsure, it is recommended to contact a professional technician for inspection and repair.
