Anonymous users2024-02-08- Is the air conditioner malfunctioning? With my 8 years of experience in repairing air conditioners, I will tell you how to solve these faults, which should save you a lot of detours.
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.
- Finally, I wish the work to go well, fix the air conditioner earlier, live a happy life——— please give an answer if you think it is good, give a good review, and wish you a better life———

Anonymous users2024-02-07Summary. It is estimated that the air conditioner is faulty.
It is estimated that the air conditioner is faulty.
I'm sorry I don't understand, but can you elaborate on that?
1. The starting capacitor of the cooling fan of the outdoor unit is damaged, the fan does not rotate, and the temperature is too high and the protection stops. It can be seen with the naked eye. If the starting capacitor is damaged, replace the fan starting capacitor.
2. If the air conditioner turns on the timing mode, the air conditioner will automatically shut down when the time reaches the predetermined time point, which is a normal phenomenon, and it is enough to restart the air conditioner. 3. If the air conditioner is in sleep mode, the remote control will automatically turn off when the temperature reaches the adjusted temperature. You can view the remote, turn off sleep mode, and change the mode to normal mode.
4. If the freon in the air conditioner is insufficient, it will also cause the air conditioner to fail to refrigerate, and the internal temperature of the air conditioner is too high, and the air conditioner will start the self-protection function and shut down. 5. In order to make the indoor temperature conditions more suitable, many users set the temperature of the air conditioner in combination with the needs of the environment, and when the air conditioner reaches the set temperature standard, the air conditioner will stop supplying air, so the air conditioner will shut down. 6. If the air conditioner is shut down during heating, it may also be caused by air conditioner defrosting.
Because the air conditioner will frost due to heat exchange when it is heating, the air conditioner will automatically defrost after working for a period of time, so the air conditioner will shut down, but after the defrosting work is over, the air conditioner will resume heating. Sometimes when we are engaged in air conditioning maintenance, if there is no sensor at hand temporarily, we can use more than 10,000 ohms of resistance to plug in the plug of the sensor to do temporary problem judgment and maintenance, and find out the problem first. This is also the application of some of the methods that we usually repair.
Look for after-sales repairs.

Anonymous users2024-02-061. Your fault phenomenon is: when heating runs for 1 minute, the temperature is far from reaching the setting, and the air conditioner is shut down for 5 minutes? When you say shutdown, do you mean the compressor shutdown of the external unit? Or is the indoor unit down and not blowing?
2. No matter what kind of shutdown, it is definitely not defrosting. How can there be an air conditioner that defrosts in 1 minute? Run for 1 minute** to remove the cream?
After running for 1 minute, the compressor is estimated to not be on high frequency! **Coming to the frost?? The frosting time is at least 20 minutes or more, and if it is an inverter air conditioner, the defrosting mainly depends on the coil temperature of the condenser, if it is a fixed-speed air conditioner, the defrosting is generally 20 to 60 minutes to start defrosting for 5 to 10 minutes.
3. And it should not be caused by the lack of refrigerant, if the lack of refrigerant is very little, it will not be shut down, but it will only be not effective when heating or cooling, if there is a lot of lack of refrigerant, it will be shut down, and it will not be shut down for 5 minutes, it should be stopped all the time and not started.
4. If it is frequency conversion; When heating for 1 minute, the temperature is far from reaching the setting, and the compressor of the external unit is shut down for 5 minutes, in this case, either the coil sensor of the outdoor unit and the ring temperature sensor of the outdoor unit are broken, or the ring temperature sensor of the indoor unit is replaced, or the communication signal of the internal and external units is problematic, or the motherboard is broken at all. These 4 possibilities.
5. If it is a fixed speed; When heating for 1 minute, the temperature is far from reaching the setting, and the compressor of the external unit is shut down for 5 minutes, in this case, either there is a problem with the communication signal of the internal and external units, or the motherboard is broken. These 3 possibilities.
6. If it is frequency conversion; When heating for 1 minute, the temperature is far from reaching the setting, and the indoor unit is stopped and does not blow for 5 minutes, in this case, either there is a problem with the communication signal of the internal and external units, or the motherboard is broken, or the motor of the internal unit is broken, these three possibilities.
7. If it is a fixed speed; When heating, it runs for 1 minute, the temperature is far from reaching the setting, and the indoor unit is stopped and does not blow for 5 minutes, in this case, either there is a problem with the communication signal of the internal and external units, or the motherboard is broken. , either the motor of the internal machine is broken, these 3 possibilities.
8. It is recommended to contact the relevant after-sales service to have a look.

Anonymous users2024-02-05What happens when the air conditioner is turned on for a period of time and stops showing E6, and then restarts after a while?
Hello, the air conditioner appears and nuclear E6 will be good for a while is caused by communication failure, the fault site is generally in the circuit control board, sensor connection and control line, in this case, the specific operation steps are as follows: 1, first of all, Huai family to power off, check whether the connection shield wire between the indoor unit and the outdoor unit is broken. 2. Then check whether the signal line of the internal machine is connected in series and whether the wiring is correct, and then re-dock and replace the line.
3. Check whether the surrounding environment is affected by magnetic field, if there is a magnetic field, signal interference needs to be excluded.
First, observe whether there is refrigeration during the 10 minutes from the start to the automatic shutdown (protection). >>>More

Three-minute popularity is an exaggeration, to the effect that you like something very much at a certain time, and you like it very much, but you will quickly lose interest after you really get it. For example, when I know the problem, I am very interested at first, but after a while, I feel bored.
