Hello everyone, Lin Fei to answer the above questions, Zhigao air conditioning fault code, many people do not know, now let's take a look at it!

With the continuous improvement of people's living standards, every family begins to use air conditioning, because air conditioning can not only provide a comfortable and comfortable environment, but also people can adjust the degree of air conditioning according to the temperature they need. in order to achieve the temperature you want. Therefore, the emergence of air conditioning provides a way for people to have the necessary temperature environment. What should we do if there is something wrong with our air conditioner, such as the fault code e4? Today, let's introduce the significance and solution of Zhigao air conditioning fault code E4.

Shiko air conditioning fault code E4 indicates that the outdoor unit is abnormal.

For the abnormal situation of the outdoor unit, we need to analyze the specific situation: if E4 occurs and continues to work for cooling, it is the temperature of the inner unit tube. If E4 does not work (does not cool), go to the outside machine to see if the compressor is working, the fan is running, and so on.

In general, Shiko air conditioning display E4 needs to be solved by the following methods:

1. Check whether the winding resistance and running current of the compressor are normal.

two。 Check whether the high and low pressure during the operation of the unit is normal.

3. Check whether the circuit is in good contact with the plug-in on the circuit board, whether the tube temperature sensor is firmly fixed, and whether the indoor unit evaporates well. Focus on checking whether the pipe temperature detected by the pipe temperature sensor reaches the cooling or heating temperature.

4. Check whether the surface of the condenser is too dirty, if so, please clean it.

5. Check the capacitance of the outdoor motor and fan for damage. If it is damaged, replace it.

6. If the above conditions are normal, replace the electronic control board.

Shigao crystal color series wall-mounted air conditioner fault code:

Displays the indoor temperature sensor fault L2 switch status, if there is a fault at the same time, the code L1 is displayed, and the indoor greenhouse inner coil temperature sensor fault is displayed immediately after maintenance.

L1 indoor fan failure L6 indoor fan is running, if there is no feedback signal within 30 seconds, it will be turned off and displayed.

L6 outdoor unit fault E5 off the display E5, set the temperature is valid, but the digital tube does not display. If you restart the machine using emergency or remote "on / off" keys, the digital tube will show room temperature.

The above is a brief introduction to the meaning and maintenance methods of Zhigao air conditioning fault code E4. I hope that when using Zhigao air conditioner, if there is a fault code E4, you can first follow the method shared above to check which part has gone wrong and how to repair that part. In fact, we know the source of the problem, and it is easy to solve, and it can be solved very quickly, so we do not need to rely on maintenance personnel to repair it.

At the end of this article, I hope it will be helpful to you.
