Question

I need some answers about one of my LG Aircon is having a humming sound and it seems to come from its fan. We are using it for about 1 and a half year now. What could be the cause of this noise?

Answer 1

A humming sound coming from the fan of your LG air conditioner could be caused by a few different factors. Here are some potential causes to consider:

1. Fan Motor Issue: Over time, the fan motor may accumulate dirt, dust, or debris, which can cause it to produce a humming noise. The motor may also develop mechanical problems or wear and tear, leading to unusual sounds.

2. Loose Components: Vibrations from the air conditioner's operation can cause various components to become loose. Loose fan blades, housing panels, or mounting brackets can result in a humming or vibrating noise.

3. Unbalanced Fan Blades: If one or more of the fan blades are misaligned or bent, it can create an imbalance, causing the fan to produce a humming sound. This issue can occur due to accidental contact with objects or general wear and tear.

4. Fan Assembly Issues: The fan assembly itself might be faulty or damaged. If the fan blades are rubbing against the housing or if the fan motor is malfunctioning, it can lead to unusual noises.

5. Electrical Problems: Electrical issues, such as loose wiring or faulty electrical connections, can also cause humming noises. These problems may require professional assistance to diagnose and resolve.

To address the issue, you can try the following steps:

1. Turn off the air conditioner and unplug it from the power source for safety.
2. Inspect the fan blades for any visible signs of damage or misalignment. If you notice any issues, contact a professional technician or LG customer support for further assistance.
3. Clean the fan blades and surrounding area to remove any dirt, dust, or debris that may be causing the noise.
4. Ensure that all housing panels, mounting brackets, and other components are securely tightened.
5. If the humming sound persists, it is advisable to contact an authorized LG service center or a qualified technician who can diagnose and repair the air conditioner.

Remember to always prioritize your safety and consult the manufacturer's guidelines or seek professional help when dealing with potential issues involving electrical appliances.
