The air conditioner disconnects the outdoor unit first, and the indoor unit will automatically shut

Working for two minutes tripping depends on whether it is a leakage protector or an overcurrent protector. If the leakage protector trips, it means that there is leakage in the air conditioning line. If the overcurrent protector trips, it means that the compressor current is too high.

Or the switch itself is faulty. Disconnect the external function to work for 12 minutes, indicating that the fault is in the external machine. The internal and external units of the air conditioner are a whole, and most of the internal and external units have sensing systems between them, if you disconnect them, the control system will not sense the relevant information, and there will be a protective shutdown.

1. The narrative should be clear, so that others can understand what the fault is;

2. "Air conditioner working", literally means that the indoor unit and the outdoor unit are working at the same time, and there is no problem;

3. When the outdoor unit is working, are you sure that the compressor is running? (You can feel the vibration of the compressor when you touch the outdoor unit)?

After a few minutes, it trips, which is generally the overcurrent protection of the compressor of the outdoor unit, and the compressor cannot start. Either the capacitance of the compressor is broken, has the capacitance capacity and quality been measured? Either the coil of the compressor is short-circuited between turns, has the current of the compressor been measured?

If there is a problem, of course it will be protected;

5. As for the 12-minute shutdown of the indoor unit, it should have little to do with the indoor unit and the control panel of the indoor unit. It may be set by the control board that if the signal of the outdoor unit is not received for 12 minutes, it will automatically shut down.

This is the failure of the condenser of the outdoor unit of the air conditioner, and it can be used normally after maintenance.

1: Either the temperature is up or the compressor is overloaded.

2: If the timing is so accurate every time, it may be that there is a problem with the board.

Cooling or dissipating air conditioning, which is the case with many machines.

Get a professional to check it out as soon as possible.

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.

After the air conditioner is turned on for about 10 minutes, the external unit automatically stops, why?

Dear, I'm glad to answer for you: After the air conditioner runs for about 10 minutes, the external unit stops automatically, why? Answer; After the air conditioner is turned on for about 10 minutes, the external unit automatically stops, as follows

For fixed-frequency air conditioners, it is basically a normal phenomenon. The control logic of the fixed-frequency air conditioner for the indoor temperature is that when the room temperature reaches 2 degrees below the set temperature, the compressor will automatically stop the refrigeration operation; When the room temperature rises to 2 degrees above the set temperature, the compressor will automatically start the refrigeration operation, and the room temperature will also decrease again until the room temperature reaches 2 degrees below the set temperature; The compressor stops automatically again, and so on and so forth. There is no specific type of start and stop cycle of this cycle, which depends on the indoor heat load and the cooling capacity of the air conditioning mechanism, but in general, it should be on for more than 3 minutes and off for more than 3 minutes.

If the ON time is particularly short, as short as 1 minute before the core, it is a problem with the refrigerant system or compressor, and the cause needs to be examined in detail by a professional.

Summary. Hello dear <>

The reason why the indoor unit of the air conditioner is stopped and the outdoor unit does not stop is because the external unit needs to dissipate heat, which may be frost on the evaporator, or it may be that the drying and mildew prevention function is turned on.

The indoor unit of the air conditioner stopped, and the outdoor unit did not stop.

Hello dear [flower dust] <>

The reason why the air conditioner is equipped with the indoor unit is stopped, and the reason why the outdoor unit does not stop is because the outdoor unit needs to dissipate heat, which may be frost on the evaporator, or it may have turned on the drying and mildew prevention function.

The solution is as follows:1Don't be in a hurry when you encounter such a situation, first of all, we need to figure out whether the external machine is working at this time, whether the compressor is working, or the insulation system of the compressor is working. If it is found that the insulation system is working, then this is a normal situation, there is no need to worry, the compressor also discharged the hot air in the residual condenser pipe when the air conditioner was working.

If you forcibly stop the operation of the fan of the external unit, it will damage the air conditioner. 2.If it is found that the compressor is still working, it is possible that there is a problem with the controller connected to the internal and external units or the relay of the compressor is damaged.

These are faults, we need to find professionals to repair and replace, for the sake of safety, we should also let them disassemble the circuit board of the internal machine, see if there is a fault, and replace the damaged parts in time.

3.The general control logic of the air conditioner is that the user clicks to turn off the air conditioner, however, the external compressor does not stop immediately, so the internal fan needs to continue to run for a while so that the air conditioner refrigerant can be completely still. We call the branch big as the remnant of the fortune to rise Zheng Zhuan.

Of course, the quick stop can choose to cut off the power directly, but it will more or less affect the normal operation of the compressor in the future, including but not limited to compressor overheating, compressor compression noise and other adverse reactions.

Unless the indoor temperature is lower than the set temperature or the air conditioner is large and the room is too small, or the indoor temperature is set higher, the outdoor unit will shut down, otherwise the control circuit of the air conditioner has a clear defense problem, which is mostly caused by the decline in the performance of the temperature sensing head. It is normal for the indoor unit not to stop working, in fact, only the indoor unit fan is running at this time, and the power consumption is very small.

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.

I think maybe your installation is not very in place, there may be poor contact in it, you can take it apart and take a look, or find a professional to take a look.
