The air conditioner is turned on for half an hour, and the machine displays E5?

This is a glitch in the display, because if you want to display the back shell character of your diagram, there should be a certain fault in the display.

This is the fault**, you can check the manual.

There are three reasons why the three models of Gree air conditioner show E5:

1. Gree fixed-frequency air conditioner displays E5 for low voltage protection.

2. Gree inverter air conditioner shows E5** as indoor and outdoor communication failure.

3. Gree split vertical cabinet air conditioner shows E5 as low voltage protection and stalled overcurrent protection.

Gree air conditioner shows the maintenance method of E5:

1. Check whether the voltage is too low, and suggest the user to install a voltage regulator.

2. Whether the external capacitor is damaged.

3. Whether the heat dissipation of the external unit is good, and whether the filter screen of the internal unit and the condenser of the external unit are too dirty.

4. If the control board fails, replace the control board.

Fault repair:

1. After disassembling the shell of the outdoor unit, the high temperature of the compressor shell is touched by your hand, which proves that the compression is indeed overcurrent protected.

2. After the power supply is cut off, further inspection is done, and the starting capacitance capacity of the compressor is measured to be 60uf, which is normal.

3. When measuring the resistance value of the winding at the three ends of the compressor, it is found that all of them are open circuits, which is actually normal, because the common end has been disconnected during the overcurrent protection of the compressor, and the compressor temperature must be cooled before testing is the real result.

4. When the voltage of the outdoor unit is measured again, it is found that there is only 160V power supply, and the speed of the external fan is also relatively slow, indicating that the E5 fault of the machine is caused by the unstable voltage.

Answer, the air conditioner display E5** generally has three meanings, and the fixed-frequency air conditioner displays E5 generally means low voltage protection. 2. The inverter air conditioner shows E5 as an indoor and outdoor communication fault, and the split cabinet air conditioner shows that E5 is generally low-voltage protection. 3. Check whether the voltage at home is too low, it is recommended that the user install a voltage regulator, the natural ambient temperature exceeds 38 degrees Celsius, which may also cause the compressor to overflow.

4. It is easiest at noon, better at night, and it is natural to wait for the natural environment temperature to drop point, check whether the heat dissipation of the external unit is good, and whether the inner filter screen and the condenser of the outdoor unit are too dirty.

n you take a look at the pro.

1.In this case, the air conditioner cannot be used temporarily. 2.

If the fixed-frequency air conditioner displays E5, it generally means under-voltage protection, that is, constant current protection. 3.The inverter air conditioner shows that the E5 is generally an outdoor communication failure.

4.If the indoor cabinet air conditioner shows E5, it generally means under-voltage protection, lock-out, and over-current protection. 5.

It may be that the motherboard is faulty, causing the air conditioner to display E51. Suggested Solution:1.

It is recommended that you can check it yourself first to see if there is a problem with the undervoltage protection current, and then you need to find a professional repairman to repair it. 2.If there is an outdoor communication failure, there is no way to solve this situation.

It is also necessary to quietly contact after-sales service personnel for maintenance. 3.If it is not an under-voltage protection or an outdoor communication failure, then it may be the air conditioner display E5 caused by a motherboard failure.

In this case, you need to find a professional to replace the motherboard to solve the problem. 4.In this case, do not turn on the air conditioner for the time being.

If you continue to use it, it may exacerbate the problem. Moreover, in this case, the general air conditioner cannot be used. It is recommended to contact after-sales personnel for maintenance in time.

The air conditioner shows that the E5 cannot be used any longer.

1. In this case, the air conditioner will be temporarily unusable.

2. If it is a fixed-frequency air conditioner.

The display of e5 generally indicates low voltage protection, and that is.

is fixed flow protection.

3. Inverter air conditioning.

The display of E5 is generally an outdoor communication outlet, and a fault has been found.

4. If it is a split cabinet air conditioner.

Display. e5, then generally stands for low voltage protection and locked-rotor overcurrent protection. Repentance and hunger.

5. It is possible that the motherboard is faulty, so the air conditioner displays E51.

Suggested workaround:

1. It is recommended to check by yourself first to see if there is a problem with the low voltage protection current, then you need to find a professional.

Maintenance personnel to carry out repairs.

2. If there is an outdoor communication failure, then there is no way to solve this situation, and you also need to contact after-sales service personnel.

to carry out the overhaul.

3. If it is not a low-voltage protection or an outdoor communication failure, then it may be the air conditioner display caused by the failure of the motherboard.

Show E5, in this case, you need to find a professional to replace the motherboard to solve this problem.

4. In this case, the air conditioner should not be turned on for the time being, if you continue to use it, it may cause the problem to worsen, and this situation is general.

The air conditioner can not be used, and it is recommended to contact the after-sales personnel for maintenance.

Air conditioner fault**e5: Low voltage overcurrent protection.

Reasons for the occurrence and how to fix it:

1. The power supply voltage is lower than 187V. Today's air conditioners are all designed with a wide power supply, but if it is lower than this number, the air conditioner will not start!

2. The protection caused by the inner filter screen and the condenser of the external unit is too dirty, it is recommended to clean it first.

3. If the control board is faulty, replace the control board Check whether the voltage is normal first, if it is unstable, it is recommended to install a voltage regulator.

E5 error** usually indicates that the outdoor unit of the air conditioner is malfunctioning. Here are some possible workarounds:

1.Check the power supply: Make sure the power cord of the air conditioner is well connected, the power switch is on, and the power voltage is normal.

2.Check the power supply of the outdoor unit of the source shield: Make sure that the power cord of the outdoor unit is well connected, the power switch is turned on, and the power voltage is normal.

3.Check the heat dissipation of the outdoor unit: Make sure that the radiator of the outdoor unit is clean, not blocked, and can dissipate heat normally.

4.Check the circuit board of the outdoor unit: If the above methods cannot solve the problem, it may be that the circuit board of the outdoor unit is faulty, and you need to find professional and technical personnel to repair or replace it.

Please note that if you are not a professional technician, do not attempt to repair the air conditioner yourself to avoid causing more damage or danger.
