What is it about the air conditioner that turns on automatically as soon as it is powered on

The reasons that cause the air conditioner to turn on automatically are:

1. Whether there are reflective objects on the opposite side of the indoor unit of the air conditioner, such as mirrors or TVs.

2. Whether the remote control is in good condition, (whether the keys are sticky, clean) and other remote controls should not be placed with the indoor unit of the air conditioner.

3. Whether it is when the power comes when the air conditioner is powered off and then turned on. I turned it on myself.。。 If yes. That is, the manual switch of the air conditioner unit is hit on the automatic, and it is good to adjust it to run.

1. Some air conditioners have a power failure compensation function, that is, the air conditioner is running and suddenly there is a power failure, and when the power comes, the air conditioner will run at the setting before the power failure. 2 Either there is a problem with your aircon emergency switch.

The air conditioner has an emergency switch in the indoor unit, in the lower right corner of the air conditioner, there is a hole, which is the emergency switch, which is known for maintenance and test machine use, generally not used, if the switch is short-circuited, then it will be automatically started, and there is a computer control system in the air conditioner that controls the special air conditioning switch, which is installed on a circuit board, when the above components are faulty, the air conditioner will be automatically started. Some air conditioners have relays, and when there is a short circuit in the relay contacts, the air conditioner will also start automatically.

1. What is the reason for the automatic switch on and off of the air conditioner?

Seventy or eighty percent of this situation occurs because of circuit problems, or for a long time, or because the circuit board is damaged. When we encounter such a problem, it is difficult for us to solve it ourselves, so you can call ** and ask the after-sales service to help deal with it. It also depends on whether the timing is set, if it is set, it will operate itself when the time is set, so don't worry too much about this.

Second, the solution of automatic on/off of air conditioner.

1.If you are not a professional person, you may not know how to repair the internal maintenance, which will lead to more serious problems and will affect personal safety.

2.If it's timed, then it's a normal phenomenon, and it will be automatically adjusted when the time is up, and now many people will use the app to control it, so don't worry too much.

3.Sometimes because the operation is too fast, it will also cause the system to be disordered, at this time, pause it to adjust, you can also check whether the remote control is out of order, you can take out the battery and install it again.

4.We can unplug it for six minutes and see if it turns on, if it does, it's fine, and if so, we need to check it.

5.Check whether there is anything that causes reflection on the opposite side of the inner machine, which may also be affected because of the angle problem.

6.It is also possible that the temperature controller of the internal unit is broken, which also needs to be dealt with by professionals, and the grid voltage may also cause such a situation.

There are several reasons why the air conditioner starts on its own:

1. Check whether the timer switch option on the remote control of the air conditioner is on, and if so, turn it off.

2. See if the remote control is in sleep mode, it will automatically turn on when the temperature reaches the adjusted temperature, and convert this mode to normal mode.

3. It is recommended to take a look at the emergency switch (manual switch) of the air conditioner, (some are on the panel of the internal unit, and some need to open the panel of the internal unit to see), unplug the power supply, and pick it back and forth with your hands, which may be caused by it not reset.

4. It can be caused by poor contact between the bolt of the air conditioning wire and the socket, you can try to unplug the air conditioner switch and plug it into other bolts to see if there will be automatic start.

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

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 of the remote control, or put the remote control as far away from the air conditioner as possible.

4.Check the air conditioner circuit board for moisture.

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

6.Whether there are reflectors on the opposite side of the air-conditioned room, such as mirrors or TVs, etc.

7.It is in the case of whether the remote control is in good condition.

8.That is, the manual switch of the air conditioner unit hits the automatic, and it is good to adjust it to run.

1. It may be that the temperature controller of the indoor unit is damaged. Open the shell of the indoor unit, there is a 3 4 cm long copper sleeve on the copper pipe coil inside, and the tube temperature sensor head is stuck inside. Air conditioning repair shops have to buy it, a few yuan a piece.

2. The outdoor unit is installed in the grille, or there is a block around it, and the ventilation is poor, resulting in protection shutdown. 3. 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.

When the fan does not rotate, replace the fan starting capacitor. 4. Most of the refrigeration leakage is lost, the refrigeration capacity of the air conditioner is greatly reduced, and the machine is easy to overheat. The air conditioner that leaks from the refrigeration economy is obviously much louder than before, and it is easy to identify.

Let the master who repairs the air conditioner add the refrigeration and check for leaks. Extended Information: Analysis and Maintenance:

1. The compressor of the outdoor unit of this machine is controlled by the AC contactor, and the AC contactor is controlled by the signal of the indoor main control board. 2. Before powering on, test the control foot of the chip compressor and find that there is no signal output, so that the AC contactor of the outdoor unit should not be engaged, and the machine will be engaged as soon as it is powered on, indicating that there is a problem with the contact of the AC contactor. 3. Adjust the multimeter to the electrical block, and after inspection, it is found that the relay is not charged when the two groups of contacts are on, remove the contactor and take a look, and find that the contacts of the contactor are bonded, and the internal spring has been broken.

4. After replacing a new AC contactor, test the machine, get it, and return to normal.

In the process of using the air conditioner, sometimes you will find that the air conditioner turns on automatically when it is turned on, what is going on? Let's find out together. 1. First of all, let's take a look at why this happens.

In fact, there are many reasons for this situation, for example: the remote control of the air conditioner is not set properly, or the air conditioner cannot be started due to a problem with the power cord. In addition, if there are too many appliances such as refrigerators or TVs used at home, it will affect the power supply in the home, which will also cause the air conditioner to fail to start.

Therefore, we must check in advance when using the air conditioner to ensure that there is no problem before using it. 2. In addition to the above reasons, there is another reason, that is: when the temperature of the mountain imitation at home is too high, then this phenomenon of automatic start-up will occur.

Because, when the room temperature is too high, it will affect the normal operation of the compressor, which will cause the compressor to stop working. At this time, in order to maintain the indoor temperature, it will automatically turn on the refrigeration system, so as to ensure that the indoor temperature will not drop too much, so as to achieve the purpose of saving electricity. Therefore, when we find that this phenomenon is happening, don't rush to shut it down, just wait for a while.

Dear, I'm glad to answer for you: Answer: The air conditioner will automatically shut down after being plugged in and running for a while, and the specific reasons are as follows: 1. There is no problem with the air conditioner, and the self-protection function is working. At present, most air conditioners have automatic protection function, which means that frequent power on and off will seriously affect the life of the air conditioner, and it will not pay attention to you.

The normal operation should be after shutting down, and then turning on the machine at least three minutes before it is normal. 2. The power module is broken and needs to be repaired and replaced. The basic methods for judging the common faults of household air conditioners are:

See, hear, touch, measure, analyze. 1. Look: Carefully observe the working conditions of each component of the air conditioner, focusing on the three parts of the refrigeration system, electrical system and wind system, and judge whether they are working normally.

You can also use a clean soft cloth and soft paper to wipe the connection between the weld of the pipeline and the joint, and observe whether there is oil stain to judge whether there is leakage. 2. Listen: Turn on the power and listen carefully to whether the operating sound of the air conditioner compressor is normal, whether there is abnormal sound, whether there is noise in the operation of the fan, whether the noise is too loud, etc.

In the operation of the air conditioner, the vibration is slight and the noise is small under normal circumstances, generally below 50db. If the vibration and noise are excessive. 3. Touch:

Touching the relevant parts of the air conditioner with your hands to feel its cold, heat, vibration, etc., is helpful to judge the nature and location of the fault. Under normal circumstances, the temperature of the condenser is gradually decreasing from top to bottom, and the temperature of the lower part is slightly higher than the ambient temperature. If the whole condenser is not hot or the upper part is slightly warm, or although it is hot, there is a significant difference in the temperature of the upper and lower adjacent pipes, it is abnormal.

Evaporator Under normal circumstances, placing a finger dipped in water on the surface of the evaporator will have a cold sticky feeling. The capillary tube at the dryer and outlet should have a warm feeling under normal conditions (slightly higher than the ambient temperature, basically the same as the temperature of the pipe at the end of the condenser), if it is felt that the temperature is lower than the ambient temperature or there is dew condensation on the surface of the spring infiltration slow, and there is a temperature difference between the sections of the thin tube of the hair mold. The suction pipe at 200mm away from the compressor should be about the same temperature as the ambient temperature under normal circumstances.

4. Measurement: In order to accurately judge the nature and location of the fault, it is often necessary to check and measure the performance parameters and status of the air conditioner with instruments and meters. For example, use a leak detector to check whether there is a refrigerant leak; Use a multimeter to measure whether the power supply voltage, the current to the ground at each terminal and the operating current meet the requirements, and the air conditioner controlled by the computer should also measure whether the potential of each control point is normal.

5. Analysis: Most of the results obtained through the above inspection methods can only reflect a certain local state. The various parts of the air conditioner are related to each other and affect each other, and a failure phenomenon may have multiple reasons, and a cause may also produce a variety of failures.

Therefore, it is necessary to conduct a comprehensive comparative analysis of local factors, so as to comprehensively and accurately determine the nature and location of the fault.

Summary. Then it may be a malfunction of the temperature sensor, if the temperature sensor fails, it will make the air conditioner unable to determine the temperature and automatically turn on.

Repair method: Replace the temperature sensor.
