What s the deal with the clattering sound of the air conditioner s indoor unit?

If the indoor unit has the same clicking sound as a mechanical timer, and it persists, it is likely to be an installation problem. At this time, if you press the shell of the indoor unit of the air conditioner with your hand, the sound will decrease or disappear, indicating that the installation plate of the indoor unit is not attached to the wall, or the wall is uneven.

Sticking the bottom plate to the wall, or trimming the wall so that the indoor unit of the air conditioner is close to the wall, can solve the problem.

If the air conditioner makes abnormal noise, it can be dealt with as follows:

2.Touch the outside of the air conditioner with your hands: If you feel a violent vibration, it means that the sound is caused by the loosening of the air conditioner. You can check whether the air conditioner screws are fixed firmly.

3.Check the evaporator for dust or foreign objects: if there is, clean it and rinse it with clean water. If it won't be disassembled, you can ask a professional to clean it.

4.Compressor damage: It is recommended to contact the local service provider directly on the manual for replacement.

If the indoor unit has a clicking sound similar to a mechanical timer, and it continues, it is likely to be an installation problem, at this time, press the shell of the indoor unit of the air conditioner with your hand, and the sound is reduced or disappears, indicating that the installation base plate of the indoor unit is not well attached to the wall, or the wall is uneven.

It is necessary to close the bottom plate to the wall, or to trim the wall flat, so that the indoor unit of the air conditioner and the wall are tightly fitted to solve the problem.

If the air conditioner has an abnormal noise, it can be dealt with according to the following methods:

1. Listen to the sound: judge whether it is from the internal or external unit of the air conditioner, the compressor is generally the sound of vibration, and the fan is generally the sound of the wind, find the source of the abnormal sound, and deal with it accordingly.

The reasons could be:

1. The filter screen of the inner machine is dirty, causing the evaporator.

the sound of freezing, and then the wind and leaves hitting the ice;

2. Normal plastics will expand and shrink after 1-2 hours of refrigeration.

When the plastic shells tighten up to each other to make a sound;

3. The fan tube barrel of the internal machine has broken blades, resulting in unbalanced rotation;

Air conditioning maintenance during normal hours

1. Remove debris from the vent to ensure proper ventilation. Observe whether the outdoor rack is loose, and clean the outdoor ventilation grille for foreign objects. At the same time, keep the vents unobstructed.

2. Clean the surface of indoor and outdoor heat exchangers to improve the efficiency of heat exchangers. When cleaning the indoor heat exchanger, you should carefully remove the panel, scrub it with a soft rag, and use a small brush to gently scrub the heat exchanger of the internal machine, so as to achieve the purpose of removing dust and harmful accumulation of multiplying germs. But pay attention due to the heat sink.

It is a very thin aluminum material, which is easy to deform after being stressed, so it should be carefully brushed.

3 Clean the dirt on the filter screen. When cleaning the filter, first cut off the power supply, and then open the air inlet grille; Remove the filter and use water or vacuum cleaner.

Clean the filter, the water temperature should not exceed 40 degrees, wash it with a hot damp cloth or neutral detergent, and then wipe it with a dry cloth, and do not clean the filter with insecticides or other chemical detergents.

The rattling of the air conditioner at night is usually due to the air conditionerLoose or aging internal componentscaused.

Here's how to fix the clatter of the air conditioner at night::

Step 1: Check the aircon installation

First of all, you need to check whether the installation of the air conditioner is firm, check whether the bracket and fixing screws of the air conditioner are loose, if you find that it is loose or the indoor unit is tilted, you need to tighten the screws in time to ensure that the air conditioner is installed firmly.

Step 2: Check the air conditioner filter

If the aircon is installed properly, you need to check whether the aircon filter is clean. If the filter is covered with dust and dirt, it will cause the internal parts of the air conditioner to loosen or deteriorate, resulting in a rattling sound. It is recommended to clean the aircon filter regularly to keep the inside of the aircon clean.

Step 3: Check the air conditioner fan

If the air conditioner filter is clean, you need to check whether the air conditioner's fan is working properly. If the fan blades are loose or aging, it will cause the internal parts of the air conditioner to become loose or deteriorate, resulting in a rattling sound. It is recommended to check the air conditioner fan regularly, and if you find a problem, you need to replace the fan in time.

Steps.

4. Check the service life of the air conditioner

After a long period of use, the core components of the air conditioner tend to deteriorate. In particular, the wear of the axle wheels of compressors and fan motors will become more and more serious, resulting in increased operating noise.

In fact, the state has clearly marked the service life of commonly used household appliances in the "Safe Service Life of Household Appliances", and the safe service life of air conditioners is 10 years.

Under normal use conditions, the higher the probability of potential safety hazards in over-serviced air conditioners, it is recommended to replace them in time.

Summary. What's going on with the air conditioner clattering at night? Hello dear!

The reasons for the clattering sound of the indoor unit of the air conditioner at night may be: 1. The filter screen of the internal unit is dirty, causing the evaporator to freeze, and then the sound of the fan blades hitting the ice; 2. After 1-2 hours of refrigeration, the normal plastic will have thermal expansion and cold contraction, and the plastic shell tightens each other to make a sound; 3. The fan tube barrel of the internal machine has broken blades, resulting in unbalanced rotation; 4. The fixation of the fan is loose; 5. During installation, the inner machine is not hung solid or the wall is uneven. Depending on the specific reason, ask a professional to come to your home to repair.

A slight clicking sound is normal :However, if it is said that it appears by accident or is suddenly discovered, it should be that some screws are loose inside, or the internal machine is not clean, and some debris collides and causes noise when the internal machine is running.

You can open the front cover of the inner unit in the case of power failure, you can first see if the fixed fan blade is loose, check whether the inside is clean, whether there is obvious dust, and then check the tightness of some screws. If it is not obvious, you can turn on the internal machine to see if there is any sound. If not, it means that the cover plate is not installed compactly, and if it still exists, pay attention to where it came from.

If it is sent by the internal motor, this is mostly a normal phenomenon of fan aging, but please pay attention to safety when operating.

As long as the function is normal, you can use it boldly, and there will be a sound of degassing when heating, that is, the outdoor unit begins to defrost, and the liquid in the air conditioner changes the flow direction, at this time, the indoor unit belongs to refrigeration, but it does not blow the wind, and then the indoor unit begins to heat and blow, so that the indoor unit has a big difference between cold and heat, and the rattling sound comes out.

The rattling sound of the indoor unit of the air conditioner at night may be caused by the following reasons:

1. Vibration and noise of the indoor unit: The indoor unit of the air conditioner will produce vibration when it is running, and if the installation is unstable or the parts are loose, it will produce noise.

Solution: You can check whether the installation of the indoor unit is firm, adjust the position of the indoor unit or tighten the screws to solve the problem.

2. Debris in the wind wheel or fan: When the wind wheel or fan of the indoor unit is running, if there is debris entering, it will make a clicking sound.

Solution: The indoor unit can be disassembled for cleaning or replacing damaged parts.

3. Loose pipes or waterways: If the pipes or old lead roads of the indoor unit of the air conditioner are loose or aging when they are running, there will be a clicking sound.

Solution: You can check whether the connection between the pipe and the waterway is tight, and if necessary, replace the damaged parts.

4. The motor of the indoor unit is faulty: When the motor of the indoor unit of the air conditioner is running, if there is a failure, it will make a clicking sound.

Solution: You need to contact professional air conditioning maintenance and grinding personnel for maintenance and maintenance.

It should be noted that air conditioning maintenance requires professional technology and equipment, if you do not understand the maintenance operation, it is recommended not to disassemble or repair the air conditioner without permission, so as not to cause secondary damage.

The sound of the air conditioner clattering at night may be caused by the following reasons:1Condensate pipes are leaking or blocked; 2.

loose or worn internal parts of the air conditioner; 3.Noise caused by air conditioner vibrations. It is recommended that professional maintenance personnel carry out inspection and maintenance to solve the problem.

1.First of all, clean the filter of the air conditioner frequently. If the filter of the air conditioner is dirty and blocked, not only the air inlet will be blocked, but the noise of the internal unit of the air conditioner will also become louder, showing low wind, and the wind speed of the air conditioner will not increase.

2.The external unit of the air conditioner is not properly fixed, and the noise generated by the vibration of the machine is abnormal. Workaround:

Fix the air conditioner feet with screws to prevent them from shaking and reduce the noise caused by vibration. 3.Check the aircon cooling fan:

Check whether the air conditioner fan blades have hit the protective net and whether the fan is loose. If the fan blades are not damaged, the noise can be reduced by tightening the fan blades. 4.

The anchor screws of the air conditioner compressor are loose, resulting in abnormal noises. Similarly, tighten the screws of the car's air conditioner compressor. 5.

The failure of the air conditioner compressor is more complicated and needs to be dealt with by professionals. Non-professionals must not tamper with it, as this may lead to greater failure. 6.

When the air conditioner is just turned on and starts working, the power of the air conditioner is relatively large at this time. Because it is necessary to quickly reach the required temperature, at this time, because the air conditioner is running relatively high, the abnormal sound of the air conditioner will appear, and the abnormal noise of the air conditioner will come down in about fifteen minutes.
