What's the reason of E5 in the air conditioner

What's the matter with the prompt of E5 appearing in Oakes air conditioner? The reason for the emergence of E5 in Oakes air conditioner, let's find out.

What is the fault of AUC air conditioner E5

E5 means that the air conditioner compressor is overloaded, the air conditioner will carry out low-pressure protection and stop automatically, and then the code E5 will be displayed on the display screen. Generally, the air conditioner will stop automatically due to the abnormal operation of the compressor.

Causes of E5 in Oakes air conditioner

1. The speed of the fan of the air conditioner is low, which may be caused by the decrease of the starting capacity of the fan.

Resolvent

It is recommended to replace the starting capacitance of the fan.

2. The external condenser hasn't been cleaned for a long time, and there is a lot of dust deposited on it. This usually appears in a single temperature machine or a dual temperature machine which is not commonly used for heating.

Resolvent

It can be solved by cleaning the condenser of the external machine.

3. The installation position of the external unit of the air conditioner is relatively high, and the outdoor environment temperature is relatively high, which leads to the abnormal cooling of the air conditioner.

Resolvent

The air conditioner does not need to be installed very high. At the same time, ensure that no other things are placed near the air conditioner to ensure its heat dissipation.

4. If the refrigerant of the air conditioner is insufficient, the internal pressure will drop and the air conditioner will have low pressure protection.

Resolvent

Find air conditioning maintenance personnel to add fluorine.

What's the fault of the air conditioner E5? The air conditioner is still normal. Suddenly, it turns off automatically and the display shows E5. What's the matter?

5. The compressor performance is not good. When the compressor is used for a long time, some problems will occur, such as the performance of the compressor is reduced, resulting in the decrease of the compressor operation efficiency.

Resolvent

Replace the compressor pole.

6. The air conditioning internal pipeline is blocked, which will cause the air conditioning pressure to be too high, and will also be automatically protected.

Resolvent

Just dredge the interior.

7. The voltage of the air conditioner connection is too low, which will cause the compressor to operate abnormally. When the voltage is lower than 90% of the normal value, it will not work normally.

Resolvent

Use the voltage regulator to stabilize the air conditioning voltage before use.
