After the Xinke air conditioner was turned on, it automatically turned off again

It's not a voltage problem, it's an air conditioning problem, the key is the problem of that control panel, I want to know where the problem is with the control panel The temperature curvature of the indoor pipe temperature has changed, change the tube temperature.

The reason why the air conditioner will automatically turn off as soon as it is turned on:

Carefully check the parameter settings of the air conditioner according to the manual, unplug the power plug and restart the air conditioner.

2.Carefully clean the indoor and outdoor units of the air conditioner, ensure that the evaporator and condenser and air filter are clean, and if necessary, purchase commercially available cleaning products to spray on the evaporation blades.

3.Refrigerant leakage due to incorrect installation of the air conditioner can lead to a protective shutdown of the compressor of the R22 refrigerant, and there is a risk of damage to the compressor itself if the compressor is used with the new R410 refrigerant. The normal operation of the compressor is that the heat of the internal motor is taken away by the evaporation of a small amount of wet steam (liquid refrigerant) in the return pipe, and if the motor of the compressor is overheated for a long time, the compressor will be damaged.

4.Check the heat dissipation of the outdoor unit, such as whether the dust filter of the air conditioner has been removed.

5.The cost of replacing the transformer of the outdoor unit of the air conditioner is about 90 yuan.

To summarize the above, after checking the problem yourself and eliminating it, you can check whether it is a problem with the compressor or the outdoor unit transformer. Note that if the air conditioner continues to run, even if there is no cold air, the compressor is generally not damaged, otherwise the air conditioner will not be able to approximate at all. At this time, we can confirm that it is problem 5, that is, the possibility of transformer damage.

The automatic start of the air conditioner may be because the set temperature is close to the room temperature, and the machine is shut down at the set temperature. The voltage is abnormal and unstable. Compressor overcurrent protection

The temperature of the coil in the room is too high, causing a protective shutdown. When the indoor temperature is 26 degrees Celsius and the outdoor temperature is above 20 degrees, the air conditioner cannot heat normally, which is easy to cause protection.

The failure of the indoor fan causes no blowing and protects the shutdown. If the outdoor fan fails, causing serious frosting, defrost is carried out, and the indoor air prevention function is entered. When the indoor unit of the air conditioner cannot work normally, the microprocessor part in the control circuit of the indoor unit should be checked, focusing on the power supply circuit, reset circuit, clock crystal oscillator and eepr0m of the microprocessor.

Maintenance during start-up:

After the air conditioner is turned on, the maintenance times during the air conditioner start-up process are determined by many factors such as environmental conditions, climatic conditions, number of hours of start-up, surrounding dust, air cleanliness, and whether the room is clean.

The environmental conditions are not good, the weather is hot, the air conditioner is outdated, the air conditioner is turned on for a long time, and the number of maintenance during the air conditioner start-up process increases, usually once every month and a half.

If the environmental conditions are good, the air conditioner is relatively new, there is less dust in the air, the air conditioner is turned on reasonably, and the electric fan is used alternately, the maintenance cycle can be appropriately extended, from the start of the air conditioner to the shutdown of the air conditioner for maintenance 1-2 times. Maintenance should be careful and careful, leaving no dead ends. Comply with the specifications, improve the refrigeration speed and refrigeration effect, and achieve energy saving, freshness and comfort.

If the air conditioner turns on automatically, these reasons are automatically turned off, and this should be a problem with the motherboard in it.

Household circuit judgment: it may be that the circuit at home is intermittent, and then it is powered on again, and the air conditioner restarts to cause the air conditioner switch to fail, at this time open the air conditioner cover, there is a manual switch in the air conditioner, and turn to the automatic top to adjust to the operation.

Automatic power on and off due to air conditioner setting: Turn down the temperature of the air conditioner setting to keep the air conditioner working, if the air conditioner is in automatic mode, then change it to large, medium and small mode, so as to avoid automatic shutdown because the indoor temperature reaches the preset value of the air conditioner.

Precautions for turning on the air conditioner.

When the air conditioner is turned on, the doors and windows will be closed tightly to prevent the air from leaking. After a long time, the indoor air will become turbid because it cannot be circulated, and because the air conditioner will reduce the humidity in the air, people are prone to symptoms such as dry and itchy throat and nose irregularity. Therefore, it is recommended to open the windows for ventilation every hour when the air conditioner is turned on, and people in an air-conditioned environment should drink more water and eat more vitamin-rich fruits.

Just enter the house, turn on the air conditioner after 10 minutes: If you just run into the house from the outside sweating profusely, don't turn on the air conditioner immediately, cool it for ten minutes, and then turn on the air conditioner after the temperature drops. In addition, be sure to turn off the air conditioner or set a timer to turn off before going to bed.

There are several reasons why an air conditioner will turn off automatically:

1.First of all, you need to check whether the air conditioner is set to turn on and off at a regular time, if it is set, it is normal for the air conditioner to automatically turn on!

2.Check whether there are household appliances near the air conditioner and whether there is electromagnetic interference! In this case, you need to turn off the electrical appliances near the air conditioner, and then whether the air conditioner will still turn on automatically!

3.Check whether the remote control of the air conditioner is out of order, and check this aspect is to take out the battery that the remote control answers, or put the remote control as far away as possible from the air conditioner!

4.Check the air conditioner circuit board for moisture.

5.Inspect the parts on the air conditioner circuit board for damage!

The above 5 points may lead to the automatic start of the air conditioner, 80% of the reasons are due to the damage or aging of the air conditioning circuit board and the automatic start of the air conditioner, in this case, you still find the maintenance of the air conditioning department of the special edition industry to repair, it is recommended that you do not disassemble it casually, in order to avoid damage to more accessories and the risk of electric shock!

1. There is a phenomenon of poor contact in the power supply circuit of the air conditioner, such as poor contact of the power cord connector, or it is caused by the desoldering of the welding leg of a certain component, resulting in the irregular automatic power failure of the air conditioner.

2. The temperature is adjusted too high, and it will automatically shut down when the temperature is reached.

3. The temperature sensor of the air conditioner is broken.

First of all, check whether the socket plug is firm, whether the line voltage and current are sufficient, and after ruling out the phenomenon of poor contact, it is an internal power supply problem and needs professional maintenance.

Whether it is in the cooling state or the heating state, it may be due to the following reasons:

The power cord or online cable is loose, resulting in poor circuit contact, causing the wiring harness of the computer board to shut down or a certain electrical device to drop tin.

The compressor is damaged.

If the refrigerant is insufficient, the indoor and outdoor fans or motors are damaged, it will not stop immediately, but will run for a period of time before stopping. The above reasons can lead to shutdown when the machine is turned on.

Summary. The air conditioner will automatically shut down after a while, this may be a part of the air conditioner failure, the air conditioner's own protection, may be the voltage instability caused by the power failure protection of the air conditioner, which needs to check the power supply, if there is always a voltage instability, it is best to change a frequency conversion air conditioner will not be like this. It is also possible that the radiator of the outdoor unit is too dirty, the heat cannot be dissipated, and the local heat is too hot, and the air conditioner will be turned off, just clean the dust and oil.

The air conditioner will automatically shut down after a while, which may be a certain part of the air conditioner, so take the obstacle, the self-protection of the air conditioner, it may be that the voltage is unstable and cause the power failure protection of the air conditioner, which needs to be checked next to the power supply, if there is always a situation of unstable voltage, it is best to change the frequency conversion of the sensitive oak air conditioner will not be like this. It is also possible that the radiator of the outdoor unit is too dirty, the heat cannot be dissipated, and the local heat is too hot, and the air conditioner will be turned off, just clean the dust and oil.

A voltage compensator has been installed and the air conditioner has been in place for seven years.

You clean the radiator of the outdoor unit.

It may be too dirty, and the heat can't get out, and it will automatically shut down.

It could be a contact issue with the electrical outlet. It may be that the internal sensor is damaged. It may be that the refrigerant is insufficient. It may be that the voltage is low or the envy is unstable. It may be that the coil temperature is too high, and the automatic protection is carried out. It could be air conditioning defrosting.

Suggested Solution:

1. If it is a contact problem with the power socket, check whether the power supply comes and goes, and whether the air conditioner plug is in good contact with the socket.

2. If the internal sensor is damaged, the sensor will be abnormal, then the air conditioner will not be able to correctly understand the indoor temperature, the air conditioner will automatically protect and shut down, check the air conditioner sensor to see if there is a failure, if the fault is replaced, the temperature sensor can be replaced.

3. Insufficient refrigerantWhen the refrigerant leaks a lot, the refrigeration capacity of the empty wheel will be greatly reduced, and the machine is easy to overheat protection, the noise of the air conditioner will be much larger than before, and the refrigerant will automatically shut down when the refrigerant is seriously insufficient.

4. Low voltage or unstable When the household voltage is relatively low or unstable, the air conditioner can not work normally, the compressor needs to work under a certain voltage, and the compressor will stop running when the voltage is insufficient. Check whether the home voltage is lower than 90% of the normal voltage, that is, less than 198V, if it is lower than this voltage may be in the peak period of electricity consumption, it is recommended to use a voltage regulator to stabilize the voltage before turning on the air conditioner.

Summary. Hello, I have seen your question and am sorting out the answer, please wait for a while After my Kelon air conditioner is shut down, it will automatically turn on, and sometimes it will automatically shut down, I don't know what's wrong?

Hello, I have seen your question and am sorting out the answer, please wait for a while The common reasons for the air conditioner to stop after running for a period of time are as follows: 1. The condenser (heat sink) of the external Kaihong group is dirty, which affects the heat dissipation. Just wash it.

2. The operating capacitance of the external machine is reduced and the speed is slowed down. Just replace it. 3. If there is something in front of or on the outside machine that affects the exhaust and air intake, it can be removed.
