Midea air conditioner is dusty and lights on, what s going on

It refers to the fact that there is too much dust inside and needs to be cleaned up. However, after the cleaning is completed, the indicator light will not go off automatically, and it needs to be eliminated by remote control. First find the digital display button on the panel, and then press and hold for about six seconds, and the indicator light will go off.

But thanks to the remote control of each air conditioner.

The panel is not the same, for those who do not have digital display buttons, you can find the screen display to solve it.

The reason why the air conditioner will be full of dust is mainly caused by excessive dust accumulation inside. In this case, we need to cut off the power supply first to ensure the safety of our lives. Then remove the filter to clean it, or clean it with a special cleaning agent, and finally install it back.

If you want to avoid this in the future, you need to clean it up regularly.

First method:

1.First of all, the anti-power cut-off;

2.Disassemble the lower part of the cabinet; If it is hang-up, there are two hidden handles (grooves) on both sides of the indoor unit, and you can lift the panel outward with a little force with both hands. If it is a cabinet machine, there are two plastic decorative caps on the plastic fence of the air inlet panel at the lower part of the machine, and the fixing bolts will be exposed when the decorative caps are removed, as long as the fixing bolts are removed.

3.Note! It is said that the air inlet filters are made of nanomaterials, so it is necessary to clean them properly, and use a soft brush to brush and shoot along the lines, and it is best not to wash with water.

4.Find the screw position or some use a clamp position to strengthen the shell, and after disassembling the shell, you can see the dust filter;

5.Remove it, wash it with water, dry it and put it back on.

The second method:

1.Remove the filter first, and then use the special cleaning agent for air conditioners to spray patiently on the condenser (the one with white aluminum sheets) in the wall-mounted and cabinet air conditioners until the water flowing from the outside water pipes is clean.

2.If there is still a phenomenon of dust and light on after cleaning the filter, then you can press the digital display button on the remote control of the Midea air conditioner to eliminate the phenomenon of dust and light on.

3.After doing the above steps, the air conditioner will still show that the dust is full, at this time, as long as you gently move your finger and press the "digital display" button of the remote control to reset, and at the same time, the cumulative running time of the indoor fan will be cleared to zero. Re-timed to eliminate.

Remind you to clean the filter, it seems to be full of dust after 200 hours of work, and it disappears by pressing and holding the remote control digital display button for 6 seconds.

4. Finally, remove the filter of Midea air conditioner KFR-72LW DY-PA400(D3).

Notes:

Midea's air conditioner is full of dust and the light is on, indicating that there is too much dust on the internal filter and needs to be removed for cleaning.

1) Before cleaning the air conditioner filter, cut off the power supply of the air conditioner to ensure the safety of the cleaner.

2) When using a tool to disassemble the wall-mounted air conditioner panel, there is a hidden handle on both sides of the indoor unit, and the panel can be lifted with a little force with both hands; When opening the panel of the cabinet, you need to disassemble the lower part of the cabinet, and after opening the panel of the air conditioner, you can take out the air conditioner filter and clean it.

2. Clean the filter screen.

The air conditioner filter can not be directly washed with water, nor can it be washed with dusty side, you can prepare a washing tool, use a soft brush to clean, it is best to brush along the lines, do not wash at will, will destroy the structure of the filter.

3. Dry the filter screen.

1) After cleaning the air conditioner filter, shake off the water droplets on it a few times, then wipe it with a soft towel, and finally put it in a shaded and ventilated place to dry.

2) Do not put the filter in the sun for exposure, because the high temperature of the sun will destroy its material and shape, wait for the filter to dry, and reinstall it back into the air conditioner.

Question: What is the reason why the air conditioner is not working when the PR is displayed on the cabinet of the United States.

The question showed that it was about ten minutes after the PR and it was working again, and that was it over and over again.

2.Detect whether the outdoor temperature sensor is consistent with the labeled value;

3.Check whether the sensor resistance of the circuit board is consistent with the temperature sensor labeling;

The air conditioner shows that the filter needs to be cleaned, the workaround is as follows:

Equipment: Haier air conditioner.

Air conditioner cleaning filter method and precautions:

When cleaning the filter, you need to use a special cleaner for air conditioners. If it is a wall-mounted air conditioner, after disassembling it, there is a handle inside it, as long as you use two hands to give a little force to uncover it, when you open it, you should uncover the lower part of it in advance, and after uncovering it, you can take out the filter for cleaning.

At the same time, there is also a way to clean the filter screen, not to clean it directly with water on the dusty side, choose to use a softer brush when cleaning it, and try to clean it along the texture when using a soft brush to avoid breaking the mesh brush.

After cleaning the filter, wipe the moisture on it, and then put it in a cool place to dry.

If the air conditioner is not cleaned for a long time, a lot of dust will accumulate, which will seriously affect the cooling and heating effect of the air conditioner. Because once too much dust accumulates on the filter screen, the wind speed will slow down, resulting in the cooling and heating effect of the air conditioner is far less than before.

At the same time, if the dust in the air conditioner is not cleaned for a long time, the wind blowing out is likely to carry bacteria, which will affect our health.

After cleaning the filter, use the remote control to align the air conditioner and press the "digital display" button to eliminate it. After the Midea air conditioner has been running for 200 hours, it will display a "full of dust" prompt to clean the filter, if there is no digital display, it can be turned off through the screen display.

After the air conditioner has been running for a certain amount of time, we need to take the initiative to deal with this aspect of the problem. Don't wait for the machine to say "full of dust" before dealing with it, in this case, the chance of air conditioning problems is much smaller.

Dusty light on explain:

Shake it off after cleaning the dust filter, as long as there is no large amount of water dripping down the panel. The filter screen is generally made of nylon or plastic, after installation, turn on the air conditioner, the indoor air will enter the internal evaporator from the inlet grille through the filter screen to cool, so it will not be long before the filter screen will be air-dried, which has no impact on the performance and effect of the air conditioner.

However, if the water droplets drip down, it may cause dirty water stains on the panel and housing, which will affect the aesthetics. It is best to clean the filter of the air conditioner every two weeks (if it is used frequently), and if the air conditioner is only turned on at night, it can be cleaned once a month to a month and a half.

After cleaning, the filter can play its due role, especially some high-end air conditioners, the filter also has special functions, such as filtering out formaldehyde, anti-mite and antibacterial, etc., after cleaning, the special function of the filter can also be restored.

The dust of Midea's air conditioner is not a fault. The dust display is a humanized prompt setting of Midea's air conditioner, and this prompt will appear on the main control board by default for a total of 200 hours of machine work, after confirming that the filter is not dirty or cleaned, press the remote control "digital display" button to reset and re-time.

After the air conditioner is used for a period of time, the word "dusty" will be displayed on the screen, which does not affect the daily use of the air conditioner, but will make people doubt that "the air conditioner is not broken". The reality is that the air conditioner is not damaged, and it is intended to remind the user to clean the filter in time.

"Dusty" solution: use the remote control to operate, the machine is turned on and press the "digital display" button on the air conditioner for about 6 seconds to release, and then press the "digital display" button again, and the "dust" can be eliminated.

The main purpose of "dusty" is to remind users to clean the filter. Many people do not pay attention to cleaning the filter, and they are not even aware of the consequences of not cleaning the filter for a long time: firstly, it may affect the operation and refrigeration effect of the air conditioner, and will affect the service life of the air conditioner, and secondly, the air inhaled by the air conditioner when it is working contains a certain amount of dust, mites, viruses and other harmful substances, which pollute the indoor air conditioning environment and affect the health of the family.

What to do if the air conditioner is dusty and the lights are on.

How to eliminate the dust and lights of the Midea air conditionerIf there is a dusty light in the use of the Midea air conditioner, it does not mean that the air conditioner is faulty, but the intelligent prompt design of the Midea air conditioner prompts that the air conditioner needs to be cleaned, if you find that the filter does not need to be cleaned after inspection, you only need to find the digital display key on the remote control of the air conditioner, press and hold for 6 seconds to hear the sound of dripping and then release it, at this time the indicator light on the air conditioner will flash and then eliminate.

Precautions for use:

1. Even if it is hot outside, the indoor air conditioning temperature should not be set too low, the most suitable temperature for adults in the air-conditioned room is 25-26 degrees, 27-28 degrees for the infirm, and the temperature difference between indoor and outdoor should not exceed 8 degrees. Therefore, it is recommended that under normal circumstances, it is best to adjust the air conditioner to about 26, and the temperature difference between indoor and outdoor should not exceed 7, otherwise it will increase the burden on the body temperature regulation center.

2. When the air conditioner is turned on, the cold air sinks downward, so it is best to blow the wind upwards to avoid the cold wind blowing directly on the body. People who are close to the air conditioner should sit facing the air conditioner, because the cold wind blows on the back and waist of the person from behind, which causes more damage to the human body than the head-on wind. If you can't move your seat, it's best to prepare a small silk scarf around your neck.
