Midea s five horse cabinet machine failure shows what is wrong with E8

Midea air conditioning. E8: Indoor and outdoor communication failure, the communication failure of indoor and outdoor units is generally due to the virtual connection of the connection line, or the failure of the main control board of the outdoor unit.

How it works. The compressor will be a gaseous refrigerant.

It is compressed into a gaseous refrigerant at high temperature and pressure, and then sent to a condenser.

The outdoor unit becomes a liquid refrigerant at room temperature and high pressure after heat dissipation, so the outdoor unit blows hot air.

Then to the capillary, into the evaporator.

Indoor unit), because the refrigerant from the capillary to the evaporator after the space suddenly increases, the pressure decreases, the liquid refrigerant will vaporize, into a gaseous low-temperature refrigerant, from the Qin and absorb a lot of heat, the evaporator will become cold, the fan of the indoor unit will blow the indoor air from the evaporator, so the indoor unit blows out of the cold air.

Water vapor in the air.

When it encounters a cold evaporator, it will condense into water droplets and flow out along the water pipe, which is the reason why the air conditioner will come out of the water Huizao.

The gaseous refrigerant then returns to the compressor to continue compressing and continuing the cycle. There is a component called the four-way valve during heating, so that the flow direction of the refrigerant in the condenser and evaporator is opposite to that of refrigeration, so when heating, the outdoor air blows cold air, and the indoor unit blows hot air.

Actually, it's junior high school physics.

The principles learned in the study of the principle of expelling heat during liquefaction (from gas to liquid) and absorbing heat during vaporization (from liquid to gas).

Summary. Hello! Midea fixed-frequency 5 HP cabinet machine display E8 reasons and solutions, Midea 5P cabinet machine display E8 fault**:

Hello! Midea fixed-frequency 5 HP cabinet display E8 reasons and solutions, Midea 5P cabinet display E8 fault**: If the fixed-speed cabinet shows E8, pure rock indicates indoor and outdoor communication failure or imitation static precipitator fault, inverter cabinet machine indicates indoor motherboard and display board through the big Zhengxun fault.

1. You can restart and wait for 30 minutes. If the E8 still appears, you can ask a professional to repair it. 2. Check whether the air conditioner freon is available, if not, ask a professional to add it.

3. Check whether the compression temperature sensor is damaged, if it is damaged, it will be replaced, and if the outdoor unit makes a sound, see if you want to add lubricating oil. 4. When you want to turn off the defrost function, you can press the mode button and the dry auxiliary hot button at the same time to exit the function. If the outside temperature is low at this time, the air conditioner will automatically turn on the defrost.

5. The indoor unit needs to be dusted, first clean the rental filter, clean the air outlet with wet wipes, open the evaporator after the filter, gently scrub the evaporator, and pay attention not to damage the filter screen when scrubbing. After cleaning, rinse the sink to drain the scrubbing dirt and prevent the drain from clogging. 6. The method of cleaning the outdoor unit is:

Cover the power supply of the air conditioner with a plastic bag to prevent water leakage when the stove is stopped cleaning, rinse the external unit with water concealment, and scrub it with a brush when rinsing. Don't worry about damaging the air conditioner when flushing, because the air conditioner is placed outdoors for a long time, if the cleaning process is found to be abnormal, you need to stop flushing immediately and wait for professionals to come. 7. After the problem is solved, the air conditioner should be cleaned and maintained regularly, and the outdoor unit and indoor unit should be cleaned once a month.

Hello! The above is the reason and solution for Midea's fixed-frequency 5 HP cabinet machine to display E8.

The fault of Midea air conditioner E8: If it is the inverter hang-up display E8, it is a communication failure between the indoor motherboard and the display panel or a dust removal reset failure; If it is a fixed-speed hang-up, E8 is a filter reset fault; If the fixed speed cabinet shows E8, it is a failure of indoor and outdoor communication or an electrostatic precipitator; If the inverter cabinet shows E8, it is a communication fault between the indoor motherboard and the display board. Internal Dust Removal Method:

You can clean the filter screen, use a toothbrush, a fine combination brush, a wet wipe, etc. After lifting the filter, clean the air outlet, the machine's drum impeller, and the dirty parts of the evaporator. Remember not to cause harm.

It is best to pour a few glasses of water along the evaporator after cleaning and rinse the sink by the way to prevent residue and dirt from clogging the drain. If possible, the plastic drain pipe of the air conditioner can be blown in the opposite direction, and the internal function can hear the sound of air flow or water bubbles. External Cleaning and Dust Removal Method:

Unplug the power of the air conditioner, connect a car wash water pipe, rinse up and down with tap water, unconditionally rinse with a plastic bucket to carry water, prepare a brush with a handle, and brush the aluminum wings up and down while washing.

Fault phenomenon: Hail indicates that E8 is faulty, and the air conditioner does not make lead cold or does not start and does not work.

Fault causes: 1. The inverter hang-up shows that E8 is a communication failure between the indoor motherboard and the display board or a dust removal reset fault.

2. The fixed-speed hang-up shows that E8 is a filter reset fault.

3. The fixed speed cabinet shows that E8 is an indoor and outdoor communication fault or an electrostatic precipitator fault.

4. The inverter cabinet traps the sail excitator and displays that the E8 is a communication fault between the indoor motherboard and the display board.

Solution: 1. Clean the air conditioner and try it.

2. Restart the air conditioner and wait for 30 minutes before trying.

The meaning of Midea air conditioner E8 fault **:

1. If the inverter hangs up and displays E8, there is a problem with the motherboard and display communication board in the room or the dust removal reset is abnormal.

2. If it is a fixed-speed hang-up E8, it means that the filter screen reset is abnormal.

3. If the fixed speed cabinet shows E8, it means that there is a problem with the communication inside and outside the room or the electrostatic precipitator is abnormal.

4. If the inverter cabinet displays E8, the communication between the motherboard and the display board in the room is abnormal.

Precautions for air conditioner maintenance:

1. If the air conditioner does not need to be used, in order to make its interior dry, it should first turn on the air supply mode for 4 hours, then add lubricating oil to its motor parts, then cut off the power supply, cover it with an envelope, and then cover the body with a protective cover, so as to avoid erosion by wind and rain.

Finally, wipe the remote control dry with a clean and soft cloth, remove the battery, and do the simplest cleaning when the air conditioner is used again, and then run it.

2. Every once in a while, you need to contact professional personnel to do a comprehensive cleaning of the air conditioner, from the core to the external parts to clean it, so that it can find its hidden problems as soon as possible, and it is very effective in prolonging its service life and maintaining its use effect.

Hello, the cause of the failure is the lack of phase failure of the compressor, and the lack of protection. The solution is as follows: 1. Check whether the wiring of each phase of the air conditioner power supply is normal.

2. Check the working status of the reverse phase protector. 3. The reverse shortage combustion phase protector itself is faulty and needs to be replaced. 4. Swap any two of the wires and try it.

5. The indoor and outdoor units do not match the fault and need to be repaired. 6. Contact after-sales personnel for door-to-door testing. Air conditioner is a room conditioner, which regulates temperature and humidity, and is a unit used to deal with air temperature changes in a space area (usually closed).

Its function is to adjust the parameters such as temperature, humidity, cleanliness and air flow rate of the air in the room (or enclosed space or area) to meet the requirements of human comfort or process.
