Do the capacitors in the washing machine affect the control board?

Capacitive principle in washing machines.

The washing machine motor is divided into three groups of coils in series, connected from end to end, leading out three wires, and the electromagnetic field generated by the three sets of circles pushes the rotor (two groups are not good), but the household appliances only have zero live wire, and the middle wire is connected to the capacitor, and the voltage connected by the capacitor is lagging behind the period of the live wire, so as to produce three groups of magnetic forces in the same direction and different times to push the rotor.

In general, the capacitor is the starting capacitor, and it also maintains the normal operation of the motor, and the motor cannot be started without the capacitor.

In general, it will not unless you choose the capacity when you replace it, and the withstand voltage is incorrect, causing the motor to start badly, and the current burns the motor and the control board.

The following happens when the washing machine capacitor is broken:

1. If the power of the washing machine is broken, the washing machine will not work and needs to be repaired.

2. If the capacitor is broken, it will leak current, and if it is used for a long time, the damage of the insulating medium will lead to the increase of leakage current, and then the heating damage.

3. The motor is an inductive load, and there will be a peak voltage during operation, and its value will be much higher than the rated working voltage, although it will not be higher than the capacitor withstand voltage, but the capacitance will accumulate damage and fail in this environment for a long time.

<> the capacity of the washing machine can not be increased, it will increase the running speed of the motor, the heat of the motor will increase, and the motor will be easily damaged. If the starting capacitor of the washing machine is damaged, you can purchase and replace it according to the original capacity.

The more common phenomenon of the washing machine capacitor breaking is that it will leak electricity, because the washing machine adopts the design of insulating medium, and once the insulation system is damaged, it will lead to leakage. The capacitance of the washing machine plays a pivotal role in the washing machine, if the capacitor is broken, the washing machine will not work properly, and it is necessary to ask professional personnel to come to repair. The motor adopts the design of inductive load, and there is often voltage in the process of operation, and the voltage of the washing machine is relatively stable in the process of working, although it will not be higher than the voltage of the capacitor standard, but in the process of long-term work, the capacitor is easily damaged.

Related questions: How to extend the service life of the washing machine There are certain precautions in the process of ordinary use, and the lid of the washing machine should not always be closed, otherwise it will lead to the breeding of bacteria inside the washing machine, which is also very unhealthy for the clothes when washing clothes.

The function of the washing machine capacitor is to increase the terminal voltage when the motor starts, so that the motor starts, rotates and works normally.

Principle: Two identical pulsed magnetic fields are formed in time and space, so that a rotating magnetic field is generated in the air gap between the stator and the rotor, and under the action of the rotating magnetic field, an induced current is generated in the rotor of the motor, and the electromagnetic field torque is generated, so that electricityThe machine spins up.

【Extended Information】Washing machine maintenance method:

1. When placing the washing machine, do not place it in a too humid place, which is easy to make the computer board in the washing machine damp, and try to place the washing machine in a cool and ventilated place.

2. When doing laundry, it is best to take out the items in the clothes, and at the same time close the zipper of the clothes to prevent damage to the laundry trough.

3. When the washing machine is running, it is best not to overload the washing machine, because it is easy to make the washing machine abnormal if the time is too long.

4. Regularly check that the washing machine is placed very horizontally, if the washing machine is tilted, it will easily lead to the phenomenon of bucketing during washing, and the noise of the washing machine will be very large.

Method 1: Connect the capacitor directly to the 220V power supply for 1-2 seconds (the time should not be too long, otherwise the capacitor will be damaged), let the capacitor be charged, and make its lead short, if there is an instantaneous strong spark, and there is a "crackling" sound, it means that the capacitor is normal, if there is only a small spark, or a very slight "crackling" sign, it means that the capacitor capacity has been reduced.

If there is no spark and no sound, the capacitor is also damaged. If your electrical appliance is under warranty, it can be replaced free of charge at Beijing Haier Washing Machine Repair Center.

Method 2: Use a multimeter to detect. Use the pointer multimeter, put the multimeter in the 1k gear, the two meter pens are connected to any two pins of the capacitor, the resistance value should be infinity, if the measured resistance value is zero or the pointer swings to the right, it means that the capacitor has been broken down or there is leakage, and it can no longer be used.

The washing machine at home is not turning, is the motor broken or the capacitor broken? The old electrician teaches you to judge quickly.

The washing machine is not good and it is broken.

The capacitor is the starting capacitor, but also to maintain the normal operation of the motor, without the capacitor motor can not start, as for the burning of the capacitor is that the motor is an inductive load, in the work will produce a reverse induced electromotive force, the induced potential voltage is higher than the supply voltage, the capacitor withstand voltage will be above 400V, but these potentials are still capacitors in the bearing, the capacitor capacity and withstand voltage in use will change, and eventually damaged, but these are related to the use of the ruler no environment and the fluctuation of the power supply.

The capacitors in the washing machine are mainly used for filtering, which can filter out the stray current in the power supply, protect the circuit and motor of the washing machine from the spine, and prevent the circuit and motor from being damaged and damaged.
