- Is the air conditioner malfunctioning? With my 7 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.
First: When the air conditioner fails, you can go to the [air conditioner failure** network] to inquire, down to the brand and model of the air conditioner. Universal remote control** query can go to the universal remote control area for inquiry.
When encountering a failure of the air conditioner, we must strictly follow the scientific procedures, and do not act blindly and disassemble at will when the situation is unclear, the fault is unclear, and there are countless in the heart. The consequence of this often amplifies existing faults, increases operating costs, shortens the normal service life of equipment, and leads to early scrapping of equipment.
The air conditioner is not refrigerated or does not refrigerate.
This problem is most common, and the lack of fluorine in air conditioners is the key.
When the machine is turned on, first touch the trachea and judge it by the temperature.
If it is cold, the speed of the fan may be low.
The inner tube scales and dust are cleaned or replaced.
If the inner tube is not considered cool, the thick tube may be flattened.
The return air temperature is not cool, and then touch the intake air to judge.
The air intake is cold and frosty, and fluoride is added to try again.
If the frost slowly disperses, it is a good decision to lack fluoride.
It is not difficult to see the aging of the press, and the lack of exhaust is the key.
Four-way gas is also commonly judged by fluoride collection.
High-pressure scales must be seen to be dirty, and they will be slow to refrigerate.
If you still don't understand, it is recommended that you go to the [Air Conditioning Fault **Net] basic knowledge area and take a look at the maintenance cases to get started.
I hope you get better and better, and the new year will be smooth, all your wishes will come true, you will be healthy, and your family will be happy.
- Finally, I wish you all the best in your work, fix the air conditioner as soon as possible, and live happily ———

Have you seen if the outdoor unit compressor is started,

Fault generation slip side scattered code: E9 means communication error, the LCD screen and the indoor unit communication line contact is poor.
Cause of failure: 1. Check whether the pin is loose, poor contact or disconnection.
2. Check whether the internal control circuit board is normal. Liquid.
3. Check whether the control circuit board of the external machine is faulty.
4. Check whether the main control circuit board is faulty.
Air conditioner not cooling reasons:
1. The power supply voltage is faulty, the voltage is low or the power input is poor;
2. The output of the electrical control system is poor;
3. The refrigeration system lacks fluorine and there are leakage points in the pipeline;
4. Poor operation of the press, poor capacitance of the press or the press itself;
5. Poor ventilation of internal and external units.
Inspection method: 1. Whether the power can be turned on, and whether the power supply and internal control are good.
2. Check the operation status of the external machine, and judge whether the signal output of the internal machine and the press are normal.
3. Detect the system pressure and judge whether the refrigerant is normal.
4. The first reason why the air conditioner is not refrigerated: freon is not enough (also known as "refrigerant" is not enough).
5. The second reason why the air conditioner is not refrigerated: the voltage of the power supply is not enough.
6. The third reason why the air conditioner is not refrigerated: the power of the air conditioner is not enough to not refrigerate.
7. The fourth reason why the air conditioner is not refrigerated: the air conditioner is not refrigerated due to the high temperature of the outside environment.
8. The fifth reason why the air conditioner is not refrigerated: the air conditioner is not cleaned and maintained for a long time.
9. The sixth reason why the air conditioner is not refrigerated: the copper pipe between the outdoor unit and the indoor unit is too long.
Reasons and solutions for refrigerator not refrigerating:1Check if there is not enough refrigerant in the refrigerator, because refrigerator refrigeration relies on the support of refrigerant. >>>More
Power issues. Sometimes it's not a problem with use, it's not a problem with the quality of the refrigerator, it may be a problem with your power supply, power supply check if the power connection is normal. Open the door and see if the lights in the box are on, or test your socket with an electric pen. >>>More
What to do if the refrigerator does not refrigerate: first, check the power supply, open the door, check whether the light is on, or test with an electric pen to see if the socket is energized. Second, check the compressor, if the power connection is normal, listen to whether the compressor is working. >>>More
Air conditioning is an indispensable part of modern life, air conditioning provides people with coolness, but at the same time, air conditioning is always on is also easy to cause diseases, such as "air conditioning disease", etc., need to be used with caution.
1: The press does not start, there is no problem with the temperature setting, but there is no response when the power is on. >>>More
