The air conditioner is still full of dust after cleaning, and it still shows full dust after the air

1.Reason 1 may be that you did not clean the dust inside the air conditioner when you cleaned the air conditioner, resulting in dust on the filter screen of the air conditioner, causing the air conditioner to display full of dust. Workaround:

You can thoroughly clean the air conditioner's filter again. 2.Reason 2 may be that the aircon cleaner did not remove all the dust, so there is dust on the aircon filter, causing the aircon to display full of dust.

Solution: You can thoroughly clean the filter of the air conditioner again. 3.

Reason 3 may be that there is a problem with the display key of the air conditioner, which causes the display to fail.

Although it shows that it is full of dust, it will not affect the use of the air conditioner. The refrigeration and air conditioner accumulates time according to the boot time, you can press and hold the display button for a few seconds, let the cumulative time reset to zero, and you can start the timing again, and the dust light will go out. When the cumulative running time of the air conditioner reaches 200 hours, it will display a full dust prompt after cleaning the filter, if it is still full of dust, you need to use the remote control to align the air conditioner, press the digital display key to eliminate it, or you can press and hold the display key and hold it for a few seconds to reset the time to zero.

If it is a hanging air conditioner with a groove on both sides of the indoor unit, gently lift the panel outward by hand, if it is the plastic of the air inlet panel under the machine of the cabinet air conditioner, there are two plastic decorative caps on the south mountain, and the fixing bolts are exposed when the decorative caps are removed, and the fixing bolts need to be removed. Then use a soft brush to brush along the lines while patting, do not clean with water, remove the dust filter and put it back after cleaning. After installing the dust filter back, you will see that the dust light is still on, so press the display button to turn off the dust light.

The dust lamp is still on, which has no effect on the air conditioner's refrigeration, but it only means that the cumulative running time of the air conditioner has reached the time point, so it needs to be cleared again.

Just press the digital display key once.

If the air conditioning filter is not cleaned for a long time, it will first affect the refrigeration effect of the air conditioner, and the dust accumulation on the filter screen will lead to a decrease in the air volume of the air conditioner, and the cooling effect of the air conditioner will become worse.

The air inhaled by the air conditioner during operation generally contains a certain amount of dust, mites, viruses, etc., which will be adsorbed on the filter screen after being intercepted by the filter, and if the air conditioner filter is not cleaned for a long time, bacteria and viruses will breed on the air conditioner filter.

Air conditioning maintenance: 1. Prevent air conditioning disease.

People who work and live in an air-conditioned environment for a long time will have nasal congestion and dizziness due to poor air circulation and the environment is not improved. Symptoms such as sneezing, tinnitus, fatigue, memory loss, etc., can even lead to symptoms related to allergic characteristics, such as tightness, dry hair, allergies, deterioration, etc. This kind of phenomenon is called in modern medicine"Air conditioning syndrome"or"Air conditioning sickness"。

2. Extend the service life of the air conditioner.

After the air conditioner is used for a period of time, due to the action of static electricity and repeated air circulation, a large amount of dust and dirt accumulate on the surface of the fins of the filter, radiator and evaporator, resulting in blockage of the airflow, resulting in a decrease in the cooling and heating effect. Increase power consumption, noise, serious and even cause compressor damage, increase the failure rate. Reduce the service life of the air conditioner.

It will also produce peculiar smells, breed bacteria, mites, etc., and endanger people's health.

3. Save electricity resources.

In the countless repeated operation of the air conditioner, a large amount of dust and liquid smoke in the air will wrap the heat sink layer by layer, and seriously block the tiny gap between the heat sinks, affecting the heat dissipation of the heat sinks, resulting in an increase in the pressure of the condenser, an increase in the current of the compressor motor, a multiplication of the running time, and a significant increase in power consumption.

If there is dust full, clean the dust filter of the indoor unit according to the manual, and there is still dust after installation, as long as you press the "digital display" button, there will be no more.

Cleaning the air conditioner is mainly to clean the panel and dust filter of the air conditioner regularly. So, what exactly is the best way to get the best cleaning results?

1..First of all, remove the dust filter according to the manual, and pay attention not to touch the metal part of the indoor unit when disassembling to prevent it from being scratched.

2.After removing the air filter, gently pat or use an electric vacuum cleaner to remove the dust. If the dust filter accumulates too much dust, it can be rinsed with water or dipped in neutral detergent with a soft brush, but the water temperature should not exceed 50 or more during cleaning, and washing powder, dish soap, gasoline, banana water, etc. cannot be used to avoid the deformation of the dust filter.

Also, do not clean with a sponge, as this will damage the surface of the dust filter.

3.After rinsing with clean water, wipe dry with a soft cloth or put it in a cool place to dry, never expose it to the sun or dry it in an open flame such as a stove, so as to avoid the deformation of the dust filter.

4.To clean the panel, gently wipe with a soft cloth dampened with warm water or mild detergent, then dry with a dry, soft cloth. There is also a way to remove the air conditioner and clean every part of the air conditioner, but this kind of cleaning is not suitable for household air conditioners, and is generally used in restaurants, where the smoke or dust is larger.
