The induction cooker turns off automatically after two minutes of turning on What s going on

Because the internal electric fan is damaged, resulting in the inability to dissipate heat normally, because the fan does not work, the high-power components IGBT, full bridge, wire reel, etc. will produce high temperatures, because there is a temperature sensitive resistor on the wire reel, when the temperature is too high, it will stop heating protection;

There is also a temperature sensitive under the high-power IGBT, which is used to sense the temperature of the power tube, when the working time is too long and its temperature rises to a certain limit, the temperature sensitive will send a signal to the control system to overtemperature and finally stop heating and display E6**;

The performance of high-power components is poor, and the current increases, causing the circuit protection to stop heating;

The defective IGBT drive circuit causes the IGBT operating current to increase, and finally the protection circuit operates and the heating stops.

Solutions to the above problems:

Replace the electric fan according to the original model to ensure that the internal accessories have normal heat dissipation;

Let the machine take a break appropriately, and continue to work when the fault** disappears after heat dissipation;

Replace the accessories with poor high-power performance to ensure the stable operation of the circuit;

Check the drive circuit components, and replace them in time if they are damaged, so as to ensure that the drive voltage of the IGBT is stable and can work normally.

Note: If there is a hidden fault in the circuit, this will also happen, pay attention to the accuracy and stability of the three standard voltages (5V, 18V, 300V) during maintenance.

The most likely reason: the fan is broken, it can't dissipate heat, and the induction cooker is automatically overheated and protected.

Induction cooker, also known as induction cooker, was born in Germany in 1957 as the first household induction cooker. In 1972, the United States began to produce induction cookers, and in the early 80s of the 20th century, induction cookers began to sell well in Europe, America and Japan. The principle of the induction cooker is the phenomenon of electromagnetic induction, that is, the alternating current is used to generate an alternating magnetic field that changes the direction through the coil, and a vortex current will appear inside the conductor in the alternating magnetic field (the reason can refer to Faraday's law of electromagnetic induction), which is caused by the movement of the carriers in the conductor (the electrons in the pot are not iron atoms) driven by the vortex electric field; The Joule heating effect of the vortex current heats up the conductor and thus heats up.

Hello, the phenomenon you are talking about may generally be the following problems:

1. Your induction cooker fan is broken or the fan does not rotate due to other reasons, so the temperature generated by the IGBT cannot be dispersed, so it will be overheated and automatically shut down after a while.

2. The thermistor of the furnace surface is faulty, resulting in the induction cooker being misjudged to be high temperature and causing a protective shutdown.

3. The panel is flooded or wet, causing a slight short circuit in the panel and stopping the machine.

4. Protection shutdown due to CPU failure.

The induction cooker will heat up and stop for a while, this time the fault is very simple, a part is not replaced and repaired, and it is perfectly done.

Summary. The reason why the induction cooker will automatically stop after a while is turned on: 1. It may be that there is leakage, after the induction cooker is used for a long time, part of the greasy and moisture enters the circuit board, resulting in leakage.

Remove the circuit board, wipe it off thoroughly with a flannel cloth dipped in pine perfume, and then dry it with a hair dryer.

2. The maximum resistance of the circuit board changes, resulting in unstable resistance, resulting in automatic stopping, and the resistance of the circuit board needs to be checked and replaced.

3. If the button of the induction cooker panel leaks, it is necessary to check whether there is a fault inside the panel and replace the button with a new one.

4. It may also be caused by insufficient capacity of wires, poor contact with sockets or low voltage of the power grid. It is necessary to check the overall circuit and socket and other aspects, and deal with them according to the specific situation.

What is the reason why the induction cooker stops automatically after being turned on for a while? How to solve it?

I'm inquiring, wait a minute.

The reason why the induction cooker will automatically stop after a while is turned on: 1. It may be that there is leakage, after the induction cooker is used for a long time, part of the greasy and moisture enters the circuit board, resulting in leakage. Remove the circuit board, wipe it off thoroughly with a flannel cloth dipped in pine perfume, and then dry it with a hair dryer.

2. The maximum resistance of the circuit board changes, resulting in unstable resistance, resulting in automatic stopping, and the resistance of the circuit board needs to be checked and replaced. 3. If the button of the induction cooker panel leaks, it is necessary to check whether there is a fault inside the panel and replace the button with a new one. 4. It may also be caused by insufficient capacity of wires, poor contact with sockets or low voltage of the power grid.

It is necessary to check the overall circuit and socket and other aspects, and deal with them according to the specific situation.

If you turn on it for a while and stop for a while, and then you will turn it on again, this is because the induction cooker is relatively hot, and you are cooling the heat.

The normal situation is an induction cooker.

The greater the heat, the longer the heating time, and the shorter the intermittent time. Conversely, the lower the fire, the shorter the heating time and the longer the intermittent time.

If the induction cooker stops after a short period of time after turning it on, there are the following reasons:

1. Whether the power cord connector is loose. If the power indicator does not light up, it proves that the power is off, and try to plug it back in.

2. Thermistor.

The protection function failed, and it was protected in advance. It is necessary to go to the after-sales service for inspection and maintenance.

3. It is not suitable for induction cooker to use in pots or heating utensils, and the induction cooker will be energized for a while and will not be heated.

4. Because the circuit board is damaged due to frequent boiling rice and boiling water, the circuit component chain shirt needs to be replaced.

5. Whether the pot is flat when stir-frying, or if the pot is picked up away from the stove, the induction cooker will also stop heating.

After the use of the household induction cooker for a long time, it is inevitable that there will be such and such problems, such as connecting the external power supply but not turning on, the induction cooker will automatically stop working after heating for a period of time, the furnace will intermittently heat up and stop for a while, etc.

Induction cooker is one of the commonly used Yinyu household appliances and kitchenware that is closely related to our lives, and it is used every day to cook, steam, and stir-fry to make all kinds of delicious dishes. However, induction cookers are sometimes used improperly, or after being used for a long time, it is inevitable that there will be such and such difficult problems to solve. A few days ago, the Midea household induction cooker was broken, and I took it to the maintenance department to disassemble and test the problem, my stove is because the smell of oil smoke is too big when stir-frying, not only the induction cooker is sometimes used improperly, or after using it for a long time, it is inevitable that there will be such and such tricky and difficult to solve problems.

A few days ago, the Midea household induction cooker was broken, and I took it to the maintenance department to disassemble and test the problem, my stove was because of the attention to the air circulation of the kitchen for stir-frying, and over time, the internal circuit board of the electric differential magnetic cooker was impregnated with too many oil smoke stains, resulting in the display board not working and could not be turned on. Later, the maintenance master replaced a main circuit board to resume normal work, and it was also a chestnut that spent a lot of money to buy life experience, indicating that the daily maintenance of induction cooker household is also a very important link.

It's intelligent, and when it comes to it, he'll stop, because if it doesn't stop, the water will boil dry.

The reason why the induction cooker will automatically stop after a while and how to check and repair it:

1. Poor heat dissipation of the power tube of the induction cooker.

Damage to the induction cooker fan, loose screws of the power tube and heat sink will cause the power tube to overheat and protect the shutdown. Detects 18 rectifier diodes for the auxiliary power supply of the induction cooker.

and filter capacitors as well as electric fans.

If the fault is found, it will be treated and restored; Tighten the fixing screws of the power tube to ensure heat dissipation;

2. There is virtual welding in the circuit of the induction cooker.

Carefully inspect the solder joints of the internal circuit board and repair the suspicious areas to bring the cooker back into normal use.

Summary. The first type: the induction cooker presses the on/off key, and the timing mode will be automatically enabled if the boiling water mode is selected, generally the timing is 10 minutes (it is a protection mode to prevent people from running away from the induction cooker), if the water in the pot is added a lot, there will be 10 minutes when the water has not boiled and the induction cooker will stop working, in this case, you can choose to use other modes.

Why does the induction cooker always stop by itself?

The second type: the service life of the induction cooker is about 5 years, and there may be some electrical failures after a long time, the water you said stopped without boiling, it may be that the internal failure of the induction cooker caused the induction cooker to automatically stop running, this situation needs to find professional maintenance personnel for maintenance.

What's wrong, no.

I got you back to it.
