2.If the cooling fan motor is aging or the resistance is too high, add some oil to the cooling fan motor shaft. 3.
Start the cooling fan motor with a small capacitor (square, a few dollars each) and replace it with a new one. Extended information: When the fan is running, the vibration is abnormal.
One reason could be the unbalanced rotation of the fan rotor. At this time, the LC-810 on-site dynamic balancing system of Beijing Times Longcheng Technology can be used for failure analysis. Through the analysis of various data, including vibration acceleration, velocity, displacement, time domain spectrum and various frequency spectrum, combined with the field situation, it is possible to diagnose whether the fault is caused by poor dynamic balance.
If available, the balancing can be performed using the single-sided or double-sided field balancing function, the gravimetric test method or the influence coefficient method. Causes and solutions: There is a lot of dirt on the heat sink, it is recommended to clean the aluminum fins of the heat sink first; The cooling fan motor is aging or has a large resistance, and it is necessary to add some oil to the cooling fan motor shaft; The cooling fan motor is started with a small capacitor, and it is recommended to replace it with a new one.

The external machine has basically not been maintained since it was installed, the motor bearing is not lubricated, dry grinding, resulting in serious bearing wear, the rotor and stator are not concentrious, and they rub against each other (commonly known as sweeping), and the rotor rotation resistance increases, resulting in a decrease in speed.
2. There is a breakdown short circuit phenomenon in the winding coil of the motor. After a long period of use, the insulation of the coil enameled wire decreases, the inter-turn breakdown ignition, the motor is broken, and the motor needs to be rewound or replaced.
3. The motor is wound with foreign bodies.

Anonymous users2024-02-09What is the reason why the fan of the indoor unit of the air conditioner slows down?
The fan of the indoor unit of the air conditioner is running slowly, what is the reason Hello dear, 1. There is a lot of dirt on the heat sink, it is recommended to clean the aluminum fins of the heat sink first. 2. If the cooling fan motor is aging or has high resistance, add some oil to the shaft of the cooling fan motor. 3. The cooling fan motor starts the small capacitor (square) and replaces it with a new one.
4. The capacitor capacity of the fan startup is reduced, and a new capacitor is replaced; 5. Poor lubrication of the fan motor of the air conditioner, heating and lubricating grease; 6. The axial clearance of the fan motor is too large due to wear, which can be solved by adding gaskets; 7. If there is a foreign object or too much dust in the fan blade, the speed will decrease, which should be cleaned and cleaned; 8. If the coil part of the fan motor is short-circuited, the new motor should be replaced; 9. The fan speed control circuit is faulty. Adjust the wind speed on the remote control to high, medium and low respectively to see how the wind speed changes. Hope it helps.

What is the reason for the slow running speed of the indoor unit fan of the air conditioner, hello, there are many reasons for the slow speed of the fan of the air conditioner, it may be that the internal unit is seriously worn and needs to be lubricated; It may be that there is a short circuit fault in the motor coil and you need to contact a professional to deal with it; It may be that the power supply voltage of the fan is unstable, and the voltage needs to be checked. Precautions for the use of air conditioners: 1. The air conditioner should be powered by a special line to avoid unstable voltage.
2. Do not run the air conditioner for a long time, and after using it for a period of time, you can go outdoors for ventilation. 3. The outdoor unit needs to be installed on a flat surface to avoid noise. 4. The abnormal noise of the outdoor unit may be the broken fan blade, which needs to be replaced in time, and the temperature should not be set too low during the use of the air conditioner, which is not conducive to health.
5. When installing the indoor unit, it is necessary to check the load-bearing capacity of the wall, so as not to be unable to punch holes for installation. 6. Clean the air conditioner regularly, after a long time of use, it will accumulate dust, which will affect the refrigeration effect of the equipment. I hope my answer to the high rent is helpful to you, and finally I wish you good health and a happy mood again!
Causes of water leakage in the air conditioner:
1. The common reason for water leakage of the external unit of the air conditioner is this, the drain pipe is from the internal machine, and the internal unit blows hot air during heating, so there will be no condensation, such as the dripping water at the bottom of the external unit is also normal. Because the external machine blows cold air during heating, the defrosting function of the machine will be reduced when it is old, and the radiator of the external unit will frost or even freeze, and after the machine is automatically frosted or shut down for a long time, the frost will melt away and it will drip water. >>>More
What is going on with the air conditioner outside unit not turning - control transformer damage What to do if the air conditioner outside unit does not turn: remove the transformer, measure the primary coil without resistance, the secondary resistance value is normal, obviously, the primary coil of the transformer has been damaged, after replacing a new transformer, connect the power supply, the power indicator light is on, and the machine is working normally. What is the reason why the air conditioner does not rotate - varistor breakdown damage What to do if the air conditioner does not rotate: >>>More
Are you talking about the air conditioner not starting, it's best to find a professional air conditioner maintenance person to take a look, let him check the specific reason, he generally can't solve it.
If the humidity is too large, or the indoor evaporator is small in the air volume, the air conditioner is equivalent to being in a dehumidification state, if the air volume is really small, you need to check whether the indoor unit filter screen and the back of the evaporator are too dirty and the indoor humidity is too large. If the air volume is really small, you need to check whether the filter screen of the indoor unit and the back of the evaporator are too dirty. The return air filter of the indoor unit is dirty, or the tilt angle of the indoor unit of the indoor unit of the air conditioner is incorrect, resulting in the air conditioner blowing water. >>>More
1. Too much power.
It may be that the user turns on the electric auxiliary heating when using the air conditioner, and the electric auxiliary heating power is large and easy to trip the circuit, because the electric auxiliary heating is directly heated by the electric heating pipe or electric heating wire, its power is generally very large, and the power consumption of the air conditioner is generally not very large when the air conditioner is heated, and when the electric auxiliary heating is added, the power consumption of the air conditioner is almost doubled. >>>More
