There are many reasons for not turning, and the possible reason 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.

There are many reasons why the air conditioner does not refrigerate, the mode setting is wrong, the temperature and wind speed setting are unreasonable, please re-select the mode and set the appropriate temperature and wind speed;

If the filter screen is dirty, the air inlet and outlet of the indoor unit are blocked, and the angle of the air deflector is too small, please clean the filter screen, remove the obstruction of the air outlet, and adjust the angle of the air deflector;

If the doors, windows, exhaust fans, etc. are not closed, resulting in poor insulation effect of the room, please close the doors, windows, exhaust fans, etc.;

The room area is large, the air conditioning selection is small, and it is recommended to increase the wind speed.

If it is installed correctly, the set temperature is lower than the room temperature, and it does not start after two or three minutes, it is a malfunction. The possible faults of the external unit without rotation and refrigeration are generally as follows: failure of the temperature measuring head, failure of the computer version, and failure of the power cord of the external unit (disconnection and connection).

The reasons why the indoor unit is running, the outdoor unit is not running, and there is no air conditioning: (1) the compressor starting capacitor of the outdoor unit is faulty (2) the power supply substrate of the outdoor unit is faulty (3) the fan motor capacitor of the outdoor unit is faulty (4) the compressor of the outdoor unit is faulty (5) the indoor unit has no signal power to transmit to the outdoor unit. Reasons why indoor and outdoor units do not work:

1) The non-fuse switch is overloaded and trips off (2) The power fuse is broken (3) The receiver of the indoor unit is bad and cannot be received (4) The power substrate of the indoor unit is faulty (5) The remote control battery is out of power 1Insufficient refrigerant causes the outdoor unit not to rotate (1) Failure analysis: the role of refrigerant in the operation of the air conditioner is very important, if the air conditioning refrigerant is insufficient or leaking, then the air conditioner can not work normally, then the compressor in the outdoor unit can not absorb the refrigerant to complete the refrigeration cycle, then the compressor can not work, and eventually the outdoor unit does not rotate.

2) Fault maintenance: the air conditioner refrigerant is insufficient, we must first check whether the air conditioner has a refrigerant leakage, if there is a leak, then we need to repair the leakage part and then add refrigerant to the air conditioner. 2.

The connection line of the internal and external units is faulty, resulting in the failure of the outdoor unit of the air conditioner (1) Fault analysis: The outdoor unit and the indoor unit of the air conditioner are connected, and the internal and external units of the air conditioner can play their due role by operating and interacting with each other at the same time. If the connection between the indoor unit and the outdoor unit of the air conditioner fails, then the outdoor unit of the air conditioner will not be able to rotate.

2) Fault maintenance: If the air conditioning connection line fails, what we can do is to check the connection line and eliminate the fault, and check out which line is faulty before repairing, so that the air conditioning outdoor unit can be operated. 3.

Damage to the components causes the air conditioner to not rotate (1) Fault analysis: The components in the air conditioner are damaged after long-term use, which will also cause the air conditioner to not rotate. (2) Fault maintenance:

If the components in the air conditioner are damaged, we need to repair or replace the damaged components, so as to ensure that the air conditioner can work normally in the later operation process. 4.Air conditioner overheating protection makes the air conditioner automatically stop running (1) Fault analysis:

If the heat dissipation effect of the air conditioner condenser becomes worse, then the air conditioner will be overheated, and then the air conditioner will automatically stop running for self-protection. (2) Fault maintenance: In view of this situation, we should first clean and maintain the air conditioning condenser to ensure the good heat dissipation effect of the air conditioning condenser.

There are many reasons why the air conditioner does not refrigerate, the mode setting is wrong, the temperature and wind speed setting are unreasonable, please re-select the mode and set the appropriate temperature and wind speed;

If the filter screen is dirty, the air inlet and outlet of the indoor unit are blocked, and the angle of the air deflector is too small, please clean the filter screen, remove the obstruction of the air outlet, and adjust the angle of the air deflector;

If the doors, windows, exhaust fans, etc. are not closed, resulting in poor insulation effect of the room, please close the doors, windows, exhaust fans, etc.;

The room area is large, the air conditioning selection is small, and it is recommended to increase the wind speed.

After reaching the set temperature, the inverter air conditioner rarely stops or does not stop, and the fixed-frequency and fixed-tone external unit will shut down. Regardless of fixed frequency or frequency conversion, in the refrigeration state, the internal unit will still blow air. The compressor shutdown may be due to the fixed frequency air conditioner refrigeration reaching the set temperature and suspending the refrigeration; It may also be that the air conditioner has failed, and the specific cause of the failure needs to be detected and troubled by professional service personnel, please click on the self-service report or call Gree National Unified After-sales Service **4008365315 feedback your needs and suggestions.

The reason may be a power supply problem, you can check whether the power is out or tripped, whether the power line is open or short circuit, etc., if there is an abnormality, the power line can be repaired; The reason may be that the voltage is low, and the air conditioner cannot be started normally due to the failure to reach the rated voltage, you can measure whether the voltage is normal first, and if the bridge chain is indeed lower than the rated voltage, wait for a while, and then use the air conditioner after the voltage returns to normal; The reason may be that the air conditioning mode is not correct and is not properly adjusted to the cooling mode, which can be solved by switching the mode key on the remote control.

1. The reason may be that the outdoor unit is exposed to the sun and the overheating shutdown protection caused by the high temperature of the machine, you can suspend the use first, wait for the equipment to dissipate heat for a period of time, and then use it after the temperature drops down.

2. The reason may be that the dust accumulation of the outdoor unit of the air conditioner is too much, which leads to blockage or affects the normal heat dissipation, causing automatic shutdown protection, which can be solved by a thorough dredging cleaner You Xunzuo.

3. The reason may be the fault of the AC contactor, measure the outlet end of the AC contactor with a multimeter, if there is no voltage of 380V, it proves that there is indeed a problem here, which can be solved by replacing the new AC contactor.

4. The reason may be the failure of the compressor, which can be repaired and solved.

Precautions when installing and using the outdoor unit of the air conditioner:

1. When choosing the location of the outdoor unit of the air conditioner, it is necessary to pay attention to the place where the air conditioner is ventilated and has good heat dissipation, and it is necessary to avoid wind, sun and rain as much as possible, which is conducive to ensuring the operation performance of the air conditioner and prolonging the service life of the equipment.

2. It is very important to install the outdoor unit of the air conditioner safely and steadily, and it must be sure to be firm.

3. If the outdoor unit of the air conditioner is not cleaned for a long time, a large amount of dust will accumulate, which is easy to cause blockage and affect the normal operation, so it needs to be checked and cleaned regularly.

4. Do not place sundries in the outdoor unit of the air conditioner, which will affect the heat dissipation, and there are potential safety hazards, especially flammable gases or items should not be close to the air conditioning equipment.

Air conditioning should be familiar to everyone! Air conditioners are one of the most important appliance brands. Air conditioning can be used in summer or winter.

In winter, air conditioners can be heated to raise the temperature. In the summer, we can use the cooling effect of the air conditioner to lower the indoor temperature. The air conditioner is composed of an indoor unit and an outdoor unit, which I believe most people know!

I think there must be a lot of faults in the air conditioner that everyone usually uses! I think we've all had the trouble of the outdoor air conditioner. Here's a detailed way to solve this situation.

Analysis of the reasons why the external air conditioner does not turn and does not refrigerate;

1.Sudden power failure: If the outdoor unit of the air conditioner does not rotate due to a sudden power failure at home, we must check whether the incoming calls of the indoor unit and the outdoor unit are normal, because the indoor unit and the outdoor unit are connected through AC contactors.

2.Condenser failure: The failure of the general air conditioner is mostly due to the damage of the condenser.

Outdoor condensers also have their own self-protection system. When cleaned up from time to time, it will start its own protection system. So in order not to cause unnecessary trouble, we clean up regularly as much as possible.

3.Freon leakage: There is a limit to the amount of freon. Too much or too little can cause the air conditioner to not work properly. At this time, the self-protection system of the air conditioner will be triggered, and the high-voltage protection automatic Huaiyou switch will appear for self-protection.

The reason may be a power supply problem, you can first check whether the power supply of the air conditioner is connected normally, whether there are problems such as loose and falling off, poor contact, open circuit or open circuit, and repair and solve it from the perspective of power connection; The reason may be that the voltage is insufficient, if the power supply has been connected normally, but the air conditioner still cannot start, it may be that the voltage is too low and does not reach the rated voltage, you can wait for the voltage to return to stability and then try to start the air conditioner. The reason may be a problem at the motherboard of the air conditioner, you can check whether the motherboard wiring is correct, if the wiring is normal, you need to contact the after-sales service to apply for repair to solve it.

Precautions when installing and using the outdoor unit of the air conditioner:

1. When choosing the location of the outdoor unit of the air conditioner, it is necessary to choose a place that is ventilated and ventilated and has good heat dissipation, and it is necessary to avoid wind, sun and rain as much as possible, which is conducive to ensuring the operation performance of the air conditioner and prolonging the service life of the equipment.

2. It is very important to install the outdoor unit of the air conditioner safely and steadily, and it must be sure to be firm.

3. If the outdoor unit of the air conditioner is not cleaned for a long time, a large amount of dust will accumulate, and the wild ride will easily cause blockage, affecting the normal operation, and it needs to be checked and cleaned regularly.

4. Do not place sundries in the outdoor unit of the air conditioner, which will affect the heat dissipation and have potential safety hazards, especially flammable gases or items should not be close to the air conditioning equipment.
