The air conditioner is turned on for about ten minutes, and the internal and external units are shut

First, observe whether there is refrigeration during the 10 minutes from the start to the automatic shutdown (protection).

If there is refrigeration, there are four possible faults that will lead to automatic protection.

1.There are too many frions. Causes excessive current, excessive current through the inductor on the circuit board, and automatically protects the shutdown.

2.The heat dissipation conditions of the host computer are too poor, causing excessive current, and the current passing through the inductor on the circuit board is too large, so as to automatically protect the shutdown.

3.There are two heat-sensitive resistors on the evaporator of the indoor unit, the black one is the indoor temperature sensor, and the copper one is the evaporator temperature sensor, and this phenomenon will occur after the resistance is damaged.

4.Five-horse machine is usually three-phase electricity, check if the voltage is low or too different?

If it is not refrigerated, there are the following reasons:

1.The complete leakage of the Frion leads to no refrigeration, you know: the reflux of the Frion has a very important cooling effect on the compressor.

If there is no cooling for a long time, the induction on the evaporator will transmit the signal to the CPU of the motherboard, and the CPU will implement compression power-off protection. and there is a signal light or display display fault**.

I guess the current problem is the poor heat dissipation of the host, and I am looking at the heat dissipation fins of the cleaning host.

It is estimated to be thermal protection. If you are sure that the external unit is working and stops, it is generally the internal filter that is dirty. Remove it and clean it. It seems that the temperature sensor is also prone to breakage. If you can't clean it first, find a maintenance person.

If the indoor tube temperature sensor is faulty, just replace the tube temperature sensor of the same specification.

Is the external compressor very hot? The key cause may be fluoride deficiency! Let the pros check it out!

Some of the external shutdown is normal, is the saving of the air conditioner, if the internal machine appears continuous, please ask professionals to repair

The wire connection is wrong, check whether the wire connection is correct, and the panel is color-marked.

The indoor unit of the air conditioner is running normally, and the compressor is shut down for three to five minutes after turning on the machine.

To sum up, it is nothing more than these aspects;

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 environmental needs, 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 we usually repair.

The air conditioner is fixed-frequency, and the temperature is set to two, one is the number of degrees, and the other is the width of the temperature, such as: when the temperature is set to 26 degrees and the temperature width is 2 degrees, the air conditioner outdoor unit starts the refrigeration when the indoor induction temperature is 25 degrees and stops when it reaches 27 degrees, and then starts the refrigeration when the indoor induction temperature returns to 25 degrees, which is the working principle of the fixed-frequency air conditioner. If you feel that the actual temperature is not the same as the displayed temperature, it is a fault of the indoor unit's thermostat.

1. The automatic mode may be turned on, when the set temperature is close to the room temperature, it will stop when the set temperature is reached. It creates the illusion of failure when it is turned on and stops, but there is no problem with the actual air conditioner.

2. The voltage is abnormal and unstable. Compressor overcurrent protection. It is recommended to try a different voltage stabilizing device.

3. The temperature of the indoor coil is too high, resulting in 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.

4. 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.

5. The starting capacitor of the compressor is faulty, and after a period of operation, the starting capacitor is faulty and short-circuited, causing the compressor to stop running.

There are many reasons for the estimated thermal protection shutdown of the compressor, such as poor ventilation of the outdoor unit, low fan speed or blade deformation and fracture, abnormal pipeline pressure, etc. Should contact the seller or after-sales service in time for return or maintenance.

The air conditioner crashes after one to twenty minutes of being turned on. The probable cause is the phenomenon of the compressor protection device tripping. Compressor overload protection will trip, indicating that the system is too high-pressure, the pressure is too high, or the overheating current is too high.

Causes and elimination of high pressure and overheating:

1. Too much refrigerant. Reduce the refrigeration dose appropriately.

2. Poor heat dissipation. Check the condenser pipe for dirt and dirt and clean the condenser.

3. The pipeline system is blocked. Refer to the pressure gauge to judge, eliminate, and re-process systematically.

4. Dust and fouling of the evaporator or filter screen. The airflow becomes smaller, the system pressure and temperature are unstable, and the evaporator or filter is cleaned.

5. Fluoride deficiency is also possible. When there is a lack of fluorine, the compressor discharge temperature will overheat, causing the overheating load protection switch to trip.

The electrical problem is:

1. Control circuit board failure.

2. The temperature sensor is overloaded and the information is wrong.

3. The power supply wiring is loose and the contact is poor.

4. The starting capacitor or compressor starting coil is burned out.

It is recommended to find a professional maintenance personnel to check it.

Summary. Hello, sorry to keep you waiting.

The air conditioner will shut down when it reaches the temperature normally, and then start up when the room temperature rises and then stop when the temperature is reached. Abnormal shutdown generally refers to a problem with the air conditioner, and the basic problems are as follows:

1. Lack of fluorine or too much fluorine, lack of refrigerant in air conditioner will lead to compressor thermal protection;

2. The power supply voltage is insufficient, and the mains power supply is unstable;

3. The starting capacitance of the compressor is broken, and the sensing probe of the internal machine is broken;

4. The external radiator is dirty or has poor heat dissipation. If you rule out these problems or shut down, then you need to check the circuit, either there is a problem with the output of the computer board, or there is a problem with the compressor, generally according to the above inspection can eliminate the problem.

The air conditioner stopped a few minutes after starting, what is the reason?

Hello, let you wait for a long time for the air conditioner to reach the normal temperature will shut down, wait for the room temperature to rise and then start and stop when the temperature arrives. Abnormal shutdown generally refers to the problem of the air conditioner, and the basic problems are as follows: 1. Lack of fluorine or too much fluorine, and the lack of refrigerant in the air conditioner will lead to compressor thermal protection; 2. The power supply voltage is insufficient, and the mains power supply is unstable; 3. The starting capacitance of the compressor is broken, and the sensing probe of the internal machine is broken; 4.

If you rule out these problems or shut down, then you need to check the circuit, either there is a problem with the output of the computer board, or there is a problem with the compressor, generally according to the above inspection can eliminate the problem.

Hope it can help you and have a happy life!

There may be a variety of reasons why the air conditioner stops working within a few minutes of starting, and the following are several possible reasons for the regimental town book:

1.Internal fault: There may be damaged or short-circuited parts inside the external unit of the air conditioner, which causes the air conditioner to automatically stop working after a few minutes of opening and collapsing.

2.Power supply problems: Unstable power supply voltage, short circuit of power supply line and other problems may cause the air conditioner to shut down.

3.Condenser overload: The condenser of the air conditioner's external unit may be overloaded, causing the compressor to overheat and automatically shut down.

4.Gas leakage: If the refrigerant inside the outside of the air conditioner leaks, causing the compressor to run difficult, it may lead to the automatic shutdown of the air conditioner.

If you encounter this kind of problem, it is recommended to contact a professional technician immediately for inspection and repair.
