How to eliminate the E8 electrostatic precipitator fault in Midea s frequency conversion

E8 fault** is an electrostatic precipitator fault. It means that the machine is too dirty, such as cleaning the inner machine filter, the surface of the evaporator, the fan roller, the air outlet and other parts. Maybe the condenser of the external unit should also be seen to see if it is dirty?

After all treatment, the air conditioner will save electricity and improve the cooling effect. Internal machine dust removal treatment method: clean the filter, use a toothbrush, a fine pen, wet wipes, etc. to clean the air outlet, the impeller of the first shaft of the fan hail, and the dirty parts of the evaporator after lifting the filter, remember not to cause damage.

After cleaning, it is best to pour a few cups of water along the evaporator, rinse the sink by the way, to prevent the residue and dirt from blocking the drain pipe. Cleaning and dust removal method of the external machine: unplug the air conditioner power, connect a water pipe for car washing, use tap water to rinse up and down, use a plastic Niandong bucket to carry water to rinse without conditions, prepare a brush with a handle (a few yuan a, a lot of hardware stores), brush the aluminum wings up and down while washing, and remember not to deform the aluminum wings.

Don't doubt that you are afraid of getting the circuit wet, the outside unit of the air conditioner is fine in the wind and rain, but some air conditioners with poor quality materials will rot quickly. If you still don't dare to do it or don't know how to do it, then you have to hire a professional to do the professional thing.

When this fault occurs, it should be repaired according to the following aspects:

1. Check whether the assembly of the air conditioning dust removal mechanism is in place, whether the electrostatic dust removal switch is broken, and if there is a problem, it needs to be adjusted accordingly;

2. Manually adjust the dust removal mechanism of the air conditioner to the position of dust removal, if there is a dust removal fault in standby mode, it can be judged as a fault of the main board of the air conditioner, and it needs to be adjusted accordingly;

3. The dust removal motor is directly connected to the 220V AC voltage, if the dust removal motor does not operate, it can be judged as the dust removal motor is faulty and needs to be replaced;

4. Power-on and dust removal mode, if the main board of the air conditioner has no output voltage, it can be judged as the fault of the main board of the air conditioner; If the main board of the air conditioner has an output voltage, and the dust removal motor does not operate, it can be judged that the dust removal motor is faulty; If the dust removal motor has action, but the action is not smooth, it can be judged as a fault of the air outlet frame and needs to be replaced.

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. However, it should be noted that since the heat sink is a thin aluminum material, it 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, cut off the power supply and open the air inlet grille; Take out the filter, wash the filter with water or a vacuum cleaner, 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 wash the filter with insecticides or other chemical detergents.

4 Clean the drain from dirt and buildup. The drainage part is prone to dirt deposits, so it must be thoroughly disinfected regularly to ensure smooth drainage and prevent bacteria from multiplying.

5 Check for others. Including power supply lines, plug boards, switches; Check the condition of consumable parts, such as air guide plate, sterilization and dehumidification, photocatalyst and other components, to ensure that the air conditioner is in good condition and there is no abnormality.

The failure of Midea air conditioner to electrostatic precipitator may be caused by the accumulation of dust and hair in the air. There are several ways to solve this problem:

Clean the air conditioner filter regularly. You can buy a special air conditioner cleaner or household cleaning liquid to clean the air conditioner, or use a special detergent to clean it, 1 2 times a year, which helps to maintain the effect of electrostatic precipitation.

Check if the electrostatic hand remover Genji dust collector is working properly. If there is a problem with the electrostatic precipitator, it may cause the air conditioner to not function properly, and the electrostatic cracked return precipitator needs to be replaced.

Check if the aircon motherboard is working properly. If there is a problem with the main board of the air conditioner, it may cause the air conditioner to fail to operate normally, and the main board of the air conditioner needs to be replaced.

Check if the air outlet frame is working properly. If there is a problem with the air outlet frame, it may cause the air conditioner to not operate properly, and the air outlet frame needs to be replaced.

The electrostatic precipitator failure of Midea air conditioner may be caused by static electricity, you can try the following methods to solve the fire disturbance:

Clean the aircon filter: Cleaning the aircon filter regularly can effectively reduce dust and impurities in the air and avoid the accumulation of static electricity.

Humidification treatment: Dry air is prone to static electricity, so you can use a humidifier to increase indoor humidity and reduce the generation of static electricity.

Grounding treatment: Gently grounding the shell of the main unit of the air conditioner, which can discharge static electricity to the ground and avoid accumulation on the body.

Replace the air purifier: If the electrostatic precipitator function of the air conditioner itself is malfunctioning, consider replacing the air purifier to improve the indoor air quality.

If the problem cannot be solved by the positive section mold method, it is recommended to contact the Midea air conditioning after-sales service center for repair or replacement of related parts.

The electrostatic precipitator failure of Midea's air conditioner may be caused by the damage of the electrostatic nuclear failure imitation dust collector or the accumulation of dust.

<> Midea air conditioner E8 is an electrostatic precipitator fault, repair method: clean the filter, use a toothbrush, a fine pen, wet wipes, etc. to clean the air outlet, fan roller impeller, and remove the filter screen after the evaporator is dirty, remember not to cause damage. After cleaning, it is best to pour a few cups of water along with the evaporator and rinse the sink by the way to prevent the residue and dirt from blocking the drain.

<> Midea's KFR-35GW wdaa3@ air conditioner inverter failure**E8, according to the hang-up and cabinet machine are not the same, the reason is not the same, if it is the inverter hang-up Lu Ye quietly, it is the communication failure between the indoor motherboard and the display board or the dust removal reset failure.
