How the air conditioner outside the unit is intermittently coaxing

According to the phenomenon analysis, it should be caused by the stalling of the outdoor unit fan. When the outdoor unit of the air conditioner starts the cold machine, there will be refrigeration, and soon the temperature of the condenser of the outdoor unit rises, and the refrigeration effect becomes worse, because the heat can not be dissipated, resulting in too high the refrigerant pressure, the compressor load increases, the temperature rises and makes a humming sound, until the thermal protector acts, the compressor stops running, and the compressor has no sound, and so the heat is naturally dissipated, the thermal protector recovers, and the compressor starts again, and so on repeatedly. Most of the reasons are that the fan cranking capacitor is broken.

Common fault phenomena: dirty and ice blockage of refrigeration system; clogged air filter; The air inlet and outlet are blocked by obstacles, etc.; The windings of the motor, the winding of the fan motor, the solenoid valve coil, the relay coil and the contacts are burned; Stuck fans, stuck bearings of moving parts, etc.

1. The press touched the S-tube when it started.

2. The offset position of the fan causes it to rotate irregularly when it starts.

3. The installation is not firm.

If this is the case in recent days, there are several cases.

1. The blades are broken.

2. There is a bit of a problem with the chassis of the press.

3. The motor is broken.

1.When the indoor temperature reaches the set temperature, the air conditioner will automatically shut down, and when the indoor temperature is higher than the set value, the air conditioner will automatically turn on, and so onThere is a problem with the noise of the air conditioner, and the remote control cannot be set, which is related to the quality of the manufacturer's production

The air conditioner compressor works intermittently, and the noise is caused by the resonance caused by the vibration of the compressor work. Since you have only bought it for a month, if the sound is very abnormal, you can find an after-sales service to help you take a look.

Turn on the refrigeration. Set 20 degrees. If there is a constant noise outside, the air conditioner is cooling. What needs to be addressed is noise.

This is the sound made by the outdoor unit of the air conditioner when it does not automatically start the outdoor fan, which is basically difficult to deal with.

If the air conditioner is used for a long time, the reason why the external unit is buzzing is mostly caused by the lack of oil or wear of the fan blades.

In general, this situation occurs, it is difficult for individuals to repair, and now many houses will not pre-emptible limbs to stay in the air-conditioning room, and the air conditioner can only be suspended on the wall, and can only be repaired by professional maintenance personnel, replacing the fan or adding some lubricating oil.

Second, the motor aging.

The air conditioner has a built-in DC brushless motor hall beam, if the air conditioner is used more frequently or for a long time, it may be caused by serious wear and tear in the motor, based on the internal structure of the motor, it is also difficult for individual users to repair, the most secure solution is to replace a new brushless motor, and the resonance of the external unit will be reduced a lot.

In addition, there is a situation that must be noted that sometimes the buzzing of the air conditioner is not necessarily a problem with the motor, but because the fixing screws or motor screws of the air conditioner are loose, the air conditioner will produce centrifugal force in the process of rotation, resulting in vibration. If this is the case, simply tighten the screws.

3. Other reasons.

In general, the buzzing of the air conditioner is the above two reasons, but there are some other reasons, based on personal experience, and then there is an additional cause that causes the air conditioner to hum.

If the air conditioner upstairs is not fixed and is installed directly above your own air conditioner, you may not usually feel anything, but if the air conditioner is used upstairs or downstairs at the same time, there will be a resonance situation. I hope my Echo Fu Shi answer will help you! Hope.

The intermittent humming of the outdoor unit of the air conditioner may be caused by the outdoor unit fan stalling. When the outdoor unit of the air conditioner starts the cold machine, there will be refrigeration, and soon the temperature of the condenser of the outdoor unit rises, and the refrigeration effect becomes worse, because the heat can not be dissipated, the refrigerant pressure is too high, the load of the compressor increases, the temperature rises and makes a humming sound, until the heat protector acts, the compressor stops running, and the compressor has no sound.

Summary. Installation attention to the following can be avoided Oh 1, to be installed horizontally on a stable, solid wall.

2. Its air intake and outlet should be kept unobstructed.

3. At least one meter away from the TV to avoid interfering with each other.

4. Keep away from heat sources and flammable places.

5. Do not go close to high-frequency equipment and high-power radio devices to avoid interference.

6. There should be room at both ends and above.

When the air conditioner is plugged in, the outside unit is noisy?

Hello, there will be the following situations that lead to this.

1. The main noise of the air conditioner is the air outlet of the air conditioner, when the air conditioner turns on the wind trembles at a greater silver speed, the noise value of the air conditioner will of course gradually increase, which is one of the main noise values of the air conditioner.

2. The loosening of the air conditioning panel The Li Wei of the air conditioning panel is loose. When the air conditioner is used for a long time, the panel of the air conditioner is easy to loosen due to various reasons, and the vibration generated by the air conditioner during operation will make the panels rub against each other, resulting in noise.

3. The installation of the indoor unit of the air conditioner, the installation of the indoor unit of the air conditioner, and the connection between the outdoor unit and the connection of the outdoor unit also affect the timing, use and noise of the air conditioner. If the installation of the indoor unit is not stable enough, when the outdoor unit is running, the copper pipe is connected to the indoor unit, and the indoor unit is not stable enough, it will be affected by the compressor, which will lead to the resonance of the indoor unit.

4. Hollow hail compressor air conditioning compressor This is also one of the best air conditioning noise, the noise value of the compressor is too large, which will also affect our normal use of wheel tremor and rest of the household.

Installation attention to the following can be avoided Oh 1, to be installed horizontally on a stable, solid wall. 2. Its air intake and outlet should be kept unobstructed. 3. At least one meter away from the TV to avoid interfering with each other.

4. Keep away from places where heat sources are attacked and flammable. 5. Do not go near high-frequency equipment and high-power Yucong brother radio devices to avoid interference. 6. There should be room at both ends and above.

I plugged in the power supply, and there was no noise from the outside unit when it was turned on.

You have to judge that the sound of the air conditioner is not renting Qinxin normally. Because there is a scheduled sound when the normal air conditioner is running, but this sound is very stable.

If you are not at ease, you can ask the manufacturer's after-sales service to check it, or take out the filter screen of the inner machine to clean it, so that the heat of the internal unit of the internal machine can be quickly dissipated, avoid noise and increase the heating effect.

Generally speaking, this situation is mostly due to the electromagnetic sound caused by the abnormality of the main electrical control components of the inverter air conditioner. If the outdoor unit fan is not turned on, the motor is driven by Lao Kai or the compressor is started, it is the problem of the main control board. For the sake of insurance, it is recommended to temporarily stop using the air conditioner and report to the air conditioner manufacturer for after-sales repair.

<> causes of the intermittent roar of the external unit of the air conditioner: 1. When the air conditioner starts or stops, it is normal for the plastic parts of the internal unit to expand and contract due to temperature changes. 2. The fixing screws of the external machine and the wall are loose or deformed. 3. When the air conditioner starts or stops, the refrigerant in the system.

It is normal to make a loud flowing sound before equilibrium is reached.

Excluding the above, it may also be that the fan rubs against the outer wall when it is running, and the distance between the fan and the outer wall should be adjusted in time. Alternatively, it is also possible that the fan is stuck and is given to the air conditioner fan.

Add some lubricating oil to the shaft to ensure that the fan rotates smoothly. Of course, it is not excluded that the compressor gasket resonates due to the aging of the gasket because the gasket becomes hard, or the compressor itself is noisy.

This answer is applicable to most brands of air conditioners such as Gree, Midea, and Haier.
