Fix the problem with the air conditioner making loud noises when it is turned on

When an air conditioner is used for an extended length of time without routine maintenance or cleaning, the unit will exhibit the following factors:

- There is a sound when operating.

- The air conditioner is leaking.

- The cold air is weak or not cold.

Here are some instructions on how to fix the loud noise of the air conditioner when operating to help consumers use the machine most effectively.

1. Air conditioner has deviated

After a period of use, because the air conditioner is shaken a lot during operation, the screws become loose, causing the machine to hit the wall, creating an annoying sound. To overcome this situation, you need to re-screw the screw, and the air conditioner will no longer exhibit the above phenomenon.

2. The blower is dirty

The fan is covered with dirt because the user of the air conditioner does not maintain it regularly, causing the machine to make a noise when operating.

You should contact the air conditioner and maintenance staff to fix this situation. However, the Mitsubishi Electric air-conditioner product line is always smartly designed to support maximum cleaning and cleaning of the machine.

The ability to easily clean air conditioners by hand for Mitsubishi Electric

To do this is extremely simple. First, you need to disassemble the blower valve on the front and open the air vents without special tools. Thanks to that, the cleaning and maintenance of the air conditioner are easier, overcoming the phenomenon of the machine being loud when operating.

3. The air-conditioning vent of the air conditioner is cracked

When the air-conditioning vent of the air conditioner is cracked, this causes the blower fan to make a loud noise when the machine operates.

To fix this, you need:

• Use special glue to glue the cracks in the air-conditioner window if the gap is small.
• For large cracks, you should replace the door with a new one to ensure there is no sound and ensure safety when using it.

4. Incorrect installation of an air conditioner

Installing the air conditioner on thin or convex walls can also cause the air conditioner to noise when operating.

To remedy this situation, you should:

• When installing, add a spacer between the wall and the air conditioner.

In addition, installing the indoor and outdoor units on the same wall, back to back, will make an annoying noise when the machine is operating. This is due to the active acoustic resonance of the outdoor and indoor units.

To avoid this, you need to:

• Install the outdoor unit on a separate wall, especially in the bedroom, to avoid the noise of the outdoor unit.

5. Keep in mind when using

In some cases, if users hear running water when the machine is operating, the cause is moisture in the pipe.

What you need to do now is:

• Call a technician at the service center to blow nitrogen, vacuum, and refill the gas.

In some cases, if you hear a crackling sound coming from the indoor unit when starting or shutting down, it is due to a rapid temperature change that causes the plastic shell of the air conditioner to expand, causing this noise. This is a normal phenomenon, and you do not need to worry too much.

And to minimize the noise of the air conditioner when operating, from the beginning, you should choose quality air conditioners for durability and smooth operation.

The advanced technology of Mitsubishi Electric has created super quiet air conditioners, only 21db (while the sound intensity in the recording room is 25 dB).

In addition, the Fuzzy Logic "I feel" control system automatically adjusts the room temperature based on daily usage habits, creating an atmosphere suitable for your family.

Besides, the indoor unit of the Mitsubishi Electric air conditioner is made from white, bright, thick high-grade PS plastic material, which does not cause noise and vibration of the engine and components when operating.

A unique feature that is difficult for consumers to ignore is that Mitsubishi Electric air conditioners also have a warranty of up to 2 years for all models and up to 5 years for compressors at service centers worldwide. Furthermore, when customers have problems with the air conditioner, they can call the service center at 1800 58 58 33 for advice from an enthusiastic staff member with many years of experience.
