The air conditioner keeps turning on and off, what s going on?

There are many reasons for the automatic shutdown of the air conditioner, and the specific reasons and solutions are as follows: check whether the timer switch option on the remote control of the air conditioner is on, and if so, turn it to off. See if the remote control is in sleep mode, it will automatically shut down when the temperature reaches the adjusted temperature, and you can convert this mode to normal mode.

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 you pick it back and forth with your hands, which may be caused by it not reset. Caused by poor contact between the latch of the air conditioner cord and the socket: you can try to unplug the air conditioner switch and plug it into another latch to see if there will be an automatic shutdown.

Caused by grid voltage: Because air conditioners are equipped with automatic protection function for over- and under-voltage, they will automatically shut down when the grid voltage is unstable and exceeds the allowable range. If you can't solve the problem of automatic shutdown of the air conditioner, you need to find a sales service, and let a professional maintenance personnel check the internal circuit of the air conditioner to see if a certain operating parameter is abnormal.

Normally, the automatic power off of the air conditioner is due to a problem with the circuit, or the air conditioner at home has been used for a long time, or it may be that the circuit board is damaged. When encountering this kind of problem, we operate according to the following methods: 1. Do not blindly operate if you find a circuit problem, so as not to cause danger, especially for users who are not familiar with the circuit, self-maintenance will only lead to more serious failures, and will also affect personal safety.

2. The remote control of the air conditioner is set to switch on and off at a regular time, and it is normal for the air conditioner to automatically turn on and off, and it will adjust itself when the time comes. 3. If the operation is too fast, the system will be disordered, and the air conditioner will automatically turn on and off, you can pause to readjust, and then check whether the remote control is out of order, and the battery needs to be replaced with a new one when the battery is aging. 4. The thermostat of the indoor unit is damaged, which needs to be replaced by professionals, and the problem of grid voltage will also lead to the automatic switch of the air conditioner, so it is recommended to hand it over to professionals to check and repair.

When encountering the phenomenon of automatic switching on and off of air conditioners, it should be solved as soon as possible, otherwise it will have a lot of impact on our lives, remember to operate and troubleshoot under the condition of ensuring personal safety, and leave professional circuit problems and air conditioning maintenance to professionals, which is more appropriate to avoid secondary maintenance.

This is because the air conditioner will automatically shut down when the temperature set by the air conditioner is reached. If you don't want the air conditioner to turn on and off automatically, you can directly adjust the temperature to the lowest. If the minimum temperature is not reached, then the air conditioner will always be running.

Summary. Hello, glad to be able to your question. The reasons and solutions for the automatic switching on and off of the air conditioner are as follows:

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.

The air conditioner has been automatically turned on and off, what should I do?

Hello, sincerely provide consulting services for you Sakura! Your mention key cong asked me has received it, and I am sorting out the answer for you, please wait a few minutes, I will definitely reply, don't be in a hurry.

It may be a circuit problem, such as the voltage is unstable, and the indoor temperature sensor is not good.

An air conditioner is an air conditioner. It refers to the equipment that uses artificial means to regulate and control the temperature, humidity, flow rate and other parameters of the ambient air in the building or structure.

Generally, it includes cold source heat source equipment, cold and hot medium transmission and distribution system, terminal device and other major parts and other auxiliary equipment. It mainly includes refrigeration hosts, pumps, fans and piping systems. The terminal device is responsible for using the cold and heat from the transmission and distribution to specifically treat the air state and make the air parameters of the target environment meet certain requirements.

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.

There are many types of household air conditioners, including wall-mounted air conditioners, cabinet air conditioners, window air conditioners and ceiling air conditioners, but these products have their own characteristics, and they are also different, so they should be selected according to their own needs.

There are three conditions that can cause the air conditioner to work intermittently:

1. In most cases, the air conditioning system stops working intermittently due to poor heat dissipation. Know how to clean and check the heat sink.

2. There may be a temperature sensor problem, there is a temperature sensor inside the air conditioning evaporation box, when the sensor detects that the temperature of the evaporation box is too low, the air conditioning compressor will be terminated, so check whether the temperature is damaged or not.

3. Commonly known as ice blockage, that is, there is water in your air-conditioning system, and the water freezes and blocks the pipeline after a while of air-conditioning refrigeration, at this time it is not refrigerated, and when it stops for a while, the temperature rises, and the ice melts and starts to refrigerate, so it is refrigerated, so intermittent refrigeration. A: At this time, it is necessary to change the air conditioner dryer.

For details, please call us or make an appointment for maintenance.

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 after the air conditioner is powered off, when the power is turned on, it will turn on itself, if so, it is the manual switch of the air conditioner on the automatic, and it will be good to adjust to run.

4. The heat dissipation network of the external unit is dirty, which cannot dissipate heat well, resulting in the compressor self-protection jumping shutdown.

5. It is the problem of the fan motor or capacitor of the external unit, check the fan and heat dissipation network of the external unit.

6. It may be that the voltage is unstable or the temperature sensor is deteriorated, check the voltage or the sensor [smile].

Question: Is the outdoor unit or the internal unit?

[Regarding the above question, first focus on checking whether the CPU working conditions are available]:

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.

If the power supply circuit, reset circuit, clock crystal oscillator and eepr0m of the above microprocessor are normal, and the indoor unit of the air conditioner is not working normally, the fault may be the microprocessor itself, at this time, the microprocessor of the same model can be replaced.

In this case, it may be that the switch of the computer's computer board is broken, or it may be that the switch button of the remote control is sticky and cannot be bounced, so it is always turning on and off.

See if you have set up automatic shutdown, if not, the air conditioner is faulty, it may be a line problem, such as unstable voltage, whether the indoor temperature sensor is good, the emergency switch leakage, or the internal board is faulty, the pipeline system check the compressor.

Internal and external fans. If you can't get the condenser, etc., find a professional to check it.

First of all, we need to check whether the air conditioner is set to turn on and off at a regular timeIf it is set, it is normal for the air conditioner to automatically turn on, 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.

Check whether the remote control of the air conditioner is out of order, and check whether the battery of the remote control is removed, or the remote control should be placed as far away as possible in the air conditioner, and check whether the circuit board of the air conditioner is wet. Inspect whether the parts on the circuit board of the air conditioner are damaged, and whether there are reflective objects on the opposite side of the indoor unit of the air conditioner, such as mirrors or TVs.

Precautions for the use of air conditioners

In fact, when we use the air conditioner, it is unlikely that there will be automatic power on/off, and the reason for the failure of the air conditioner automatic switch on and off is because the air conditioner circuit board is damaged or the air conditioner is automatically turned on or off due to aging, and this situation is generally encountered.

We are unable to solve the problem ourselves, so we quickly call ** to the air conditioning after-sales personnel for door-to-door maintenance, of course, it is recommended that you disassemble it yourself, and then look for the source of the problem, if it is not a professional personnel, it may lead to more serious damage and personal safety problems.

The air conditioner keeps turning on and off, what's going on?

It may be that the program settings of the system are incorrect, and the bridge is not ridged; It may be that the voltage is unstable and causes the defeat; It may be caused by a short circuit in the internal circuit, no matter what the reason, we can not solve it without authorization, it is recommended to ask professionals to come to check, check the cause one by one, and solve the fault to ensure that the air conditioner can be used normally.

When using the air conditioner, if the air conditioner is always automatically turned on and off, then it may be that the line inside the air conditioner has a short circuit.

Other reasons why the air conditioner always shuts off automatically:

1.Aging air conditioner. In general, the service life of household appliances is about 15 years, and it cannot be decades. If the internal parts of the air conditioner are damaged, it will automatically shut down and other failures, and it needs to be repaired by a professional master.

2.The power of the air conditioner is too small. There are also many friends who buy a small air conditioner that does not match the voltage of their home in order to save money, and the power of the low-power air conditioner is not enough, so that the poor effect of refrigeration cannot be achieved.

This will automatically shut down. Many of my friends have rooms that are too large in size, the space is not sealed enough, and the cooling effect is not good. Therefore, it is essential to choose an air conditioner with good quality and power.

3.There is no reset for the manual switch. The manual switch is set on the panel of the internal machine, and the panel of the internal machine needs to be opened to be visible.

If there is no reset, it will always shut down. At this time, you need to unplug the power supply first, buckle it with your hand, and check whether there is no reset. If there is no reset, it can be reset in time.

The above is the reason why the air conditioner always shuts down automatically, there are too many electrical appliances for the sake of the family, for safety, don't buy a bad air conditioner because of saving, don't be nervous when there is an automatic shutdown, and slowly investigate the relevant problems.

There is a very simple way, find after-sales maintenance.

The air conditioner turned itself on and off, probably because there was a problem with the circuit. It could also be that the air conditioner has been used for a long time, or the circuit board is damaged. It is difficult for users to deal with such problems.

It is recommended to contact a professional repairer for help. Users should also not disassemble and inspect by themselves, non-professionals do not understand the internal structure, blind maintenance will only make maintenance more difficult, and may also affect personal safety.

1.Don't be too anxious if you find a circuit problem, if the remote control of the air conditioner is set to automatically switch on and off, it will automatically adjust when the time comes, which is normal. If you need to change, simply change the time or turn off the automatic setting.

Let a professional maintenance personnel check the internal circuit of the air conditioner to see if a certain operating parameter is abnormal.

2.If the operation is too frequent and the program is disordered, it is recommended to deactivate or check whether the remote control is faulty. These repairs are simple and can be solved by the user themselves.

Automatic switching on and off of air conditioners is a common fault, after simple treatment, the problem can be better solved, and the problem that cannot be solved can be handed over to professionals in time.

3.It is not practical to install a pressure regulator and can drive the air conditioner. Since all air conditioners have the function of automatic protection against overvoltage and undervoltage, they will automatically shut down when the grid voltage is unstable and exceeds the allowable range.

If this happens frequently in the power grid, the air conditioner cannot be used and can only be solved by the power supply department.

4.The voltage regulator itself also has its own adaptive range, and too much fluctuation in the power grid to adjust will also cause the air conditioner to shut down automatically. When you can't solve this trouble, you have to find sales services. Only on-site inspections are the most targeted and authoritative.
