1 Why does the 5HP vertical air conditioner automatically stop and show E8 shortly after it is turne

The air conditioner shows that E8 is a communication fault between the indoor motherboard and the display board or a dust removal reset fault; The fixed-speed hang-up shows that E8 is a filter reset fault; The fixed speed cabinet shows that E8 is an indoor and outdoor communication fault or an electrostatic precipitator fault; The inverter cabinet shows that E8 is a communication fault between the indoor motherboard and the display board. Internal machine dust removal treatment method: 1. Clean the filter screen, use a toothbrush, a fine pen, wet wipes, etc. to clean the dirty parts of the air outlet, fan roller impeller, and evaporator after lifting the filter, and remember not to cause damage.

2. 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 drainage pipe. Cleaning and dust removal method of the external machine: 1. Unplug the air conditioner power, connect a water pipe for car washing, use tap water to rinse up and down, use a plastic 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.

2. Don't doubt that the circuit will be wet, the outside unit of the air conditioner is fine in the wind and rain, but some air conditioners with poor quality and materials will rot quickly.

If you want to ask the manufacturer to get the fault, you can know what to do, and directly find the manufacturer for the fastest after-sales.

1.The air conditioner E8 indicates that the temperature sensor of the compressor is faulty. Check that the temperature sensor of the compressor is normal.

If there is any abnormality, the temperature sensor needs to be replaced, and the pressure of the refrigerant is checked if it is too high, and if so, the pressure is returned to normal. Observe the temperature at the outlet of the outdoor unit. If the temperature is too high, the outdoor unit of the air conditioner needs to be cleaned.

2.You can restart and wait for 30 minutes. If the e8 still appears, find a professional to repair it.

3.Check the air conditioner for freon. If not, ask a professional to add.

4.Check that the compression temperature sensor is not damaged. If damaged, replace it immediately.

If there is sound from the outdoor unit, see if you need to add lubricating oil. 5.The remote control is pressed by mistake to turn on the defrost function.

If you want to turn off the defrost function, you can press the mode key and the drying auxiliary hotkey at the same time to exit the function. If the outside temperature is low, the air conditioner will automatically start defrosting.

Air conditioner shows e8 reason:

1. If the inverter hangs up and displays E8 is a communication failure between the indoor motherboard and the display board or a dust removal reset failure, it is recommended to clean up the dust of the indoor unit, which may be caused by more dust.

2. If the fixed-speed hang-up shows that E8 may be a filter reset fault, you can remove the filter and reinstall it.

3. If the fixed speed cabinet shows that E8 is an indoor and outdoor communication failure or an electrostatic precipitator fault, you can check whether there is more dust.

4. If the inverter cabinet shows that E8 is a communication failure between the indoor motherboard and the display board, and encounters a communication failure, it is recommended to find a professional maintenance personnel to check whether the connection between the indoor and outdoor units is normal.

Maintenance: 1. Do not put anything on the outdoor unit of the air conditioner to avoid the noise of the air conditioner. This can seriously affect the life of the air conditioner.

2. There must be no high-temperature heat source next to the air conditioner, so as to avoid the deformation of the air conditioner panel.

3. After the air conditioner has been running for a certain period of time, it should be shut down and the window should be opened to replace the air.

1.The air conditioner E8 indicates the temperature sensor of the compressor.

Faulty. Check that the temperature sensor of the compressor is normal. If there are any anomalies, the temperature sensor needs to be replaced, and the refrigerant needs to be checked.

If the pressure is too high, and if so, bring the pressure back to normal. Observe the temperature at the outlet of the outdoor unit. If the temperature is too high, the outdoor unit of the air conditioner needs to be cleaned.

2.You can restart and wait for 30 minutes. If the e8 still appears, find a professional to repair it.

3.Check the air conditioner for freon.

If not, ask a professional to add. 4.Check that the compression temperature sensor is not damaged.

If damaged, replace it immediately. If there is sound from the outdoor unit, see if you need to add lubricating oil to start training. 5.

The remote control mistakenly pressed the blind button to turn on the defrost function. If you want to turn off the defrost function, you can press the mode button and the drying auxiliary hotkey at the same time.

Exit the feature. If the outside temperature is low, the air conditioner will automatically start defrosting.
