When the touch Midea induction cooker is plugged in, the control panel light is fully lit and is not

Winter is coming, there are often high-power electrical appliances at home, I heard about the situation, or be careful, it must be the first time to enter the water or put it for too long, the motherboard is burned or there is a serial, just like my mobile phone and computer keyboard, after the keyboard enters the water, the beginning is also to press this key, but it is the content of another key appears, but it can be used after drying, the mobile phone is also watered, mistakenly thought that it was dried with a hair dryer, but as a result, the phone is hot, turn off and blow for a few days, and then open it can still be used, It's just that all the lights have not been extinguished, including the lights under the buttons, which are on every day, and this Nokia is dragged. And your induction cooker is used with direct current, if you can buy one, buy another one, make a lot of money, don't worry about this small money, there are no safety hazards at home, and life is more important than anything else.

The experience of the younger brother is that the tide has resurged, or it has entered the water or entered the small cockroach. Turn it on and dry it with a hair dryer. Look at the circuit board on the control panel, there is no platinum strip oxidation of the circuit, ,

Open it yourself to see if there are any components burned, capacitive touch is susceptible to static electricity.

I bought it last year.,It shouldn't have passed the warranty period.。。。

I suggest that you take the purchase invoice and warranty card, go to the place of purchase, or after-sales service, and check it specifically.

After all, it is a household appliance, and you should be careful when using it to avoid unnecessary accidents...

Wash the panel, or replace the panel.

After the induction cooker is plugged in, the indicator light is all on, and it is all off immediately, and the cause of the failure and the repair method are not working

First, the 5UF filter capacitor is soldered or out of capacitance.

Open the bottom cover of the induction cooker, remove the circuit board, solder the 5UF 450V capacitor, test its capacity, if the capacity is insufficient or out of capacity, replace the ** capacitor of the same specification;

Second, the secondary power supply circuit components are soldered or open-circuited.

Detect the 1 2 ohm 3W current limiting fuse resistor from the main power supply to the auxiliary power supply, if it has been opened, replace it with a resistor of the same specification, and solder each solder joint; Test to see if it can stabilize the output of 18V and 5V;

Third, there is sludge leakage on the circuit board of the induction cooker.

Dismantle the induction hob housing, focus on removing the sludge that has seeped into the circuit board, and use a hair dryer to dry the water.

This is the induction cooker powered on self-test, normal, and then press the switch does not work, it is estimated that the switch oxidation failure, you can change a switch, if you will not repair, you can also ask others to repair.

The main reason is that there is no normal start, and the power supply or high-power high-frequency MOSFET is abnormal, resulting in shutdown protection.

The self-test is normal, it may be that the switch is broken, try to replace it with a new one.

This is because of LED diodes.

Bad, the user can replace the LED diode.

Other reasons: 1. Induction cooker.

Internal reasons for not heating: including temperature sensors.

Open circuit, short circuit protection, IGBT tube overpressure protection, IGBT overcurrent protection. You don't have to worry about these problems when they arise, and it is enough to restart them again after a while.

2. The external reasons of the induction cooker cause no heating: including the external grid voltage is higher or lower than the working voltage range of the induction cooker, then the internal protection mechanism of the induction cooker will be forced to cut off the power for heating. If the internal temperature of the induction cooker is too high, the activation of the temperature alarm mechanism will also force the heating function to be turned off.

Precautions for the use of induction cooker:

1. The high current when the induction cooker is working will cause the wires and sockets to heat up.

or burned. If possible, it's a good idea to install a fuse box at the power cord outlet to ensure safety.

2. Place it flat: The desktop of the induction cooker should be flat, especially when eating hot pot on the dining table. If the table top is uneven, so that one foot of the induction cooker hangs in the air, the gravity of the pot will force the stove body to deform or even damage when used.

3. Ensure that the pores are unobstructed: the induction cooker in the work will heat up with the heating of the pot. Therefore, when installing an induction cooker in the kitchen, it should be ensured that there is no object blocking the inlet and exhaust holes of the furnace body.

Hello, the reason why the Midea induction cooker is not heated when it is energized is 1, the induction cooker is not heated is likely to be caused by the failure of the induction cooker, we can see whether it is because of the change of external natural factors and the damage of the internal parts of the machine caused the protection circuit to be opened, once the protection circuit is turned on, there is no way to heat the induction cooker at this time. 2. When the induction cooker works at the external voltage, there will be a protective temperature of the grid voltage, basically between 90 degrees and 95 degrees, if the induction cooker is overheated, it is likely that the internal automatic protection is carried out, and the induction cooker will not be heated at this time.

It can be double-checked.

3. It may be that the power supply of the induction cooker is not in good contact, resulting in the induction cooker not being able to heat, we can change the power supply to try it. 4. It is also possible that the induction cooker has started the anti-dry burning protection, and the induction cooker has been burning when there is no water in the induction cooker, which will easily damage the induction cooker, and the induction cooker will inspire the anti-dry burning protection at this time, so that the induction cooker has no way to heat.

Sincerely answer every question for you! Best if you're satisfied! If you have any questions, please keep asking!

Have a great day! Happy every day.

The circuit indicator is on, and the current path is connected, and the reason why it is not hot is that the disk line must be faulty and disconnected.

It is possible that the heating pipe is damaged and needs to be disassembled and checked** There is a problem.

The power supply is normal, but the heating element is damaged.

1. Flip the induction cooker.

Unscrew the screws at the four corners of the cooktop.

2. After opening the lid, find the control panel of the function keys.

Check the capacitors.

3. Check the capacitor with special testing equipment, and show that it is energized, which proves normal.

4. After checking the control board, it is found that the chip of the control board is faulty.

5. Re-weld the click of the control board.

6. Then put the circuit board back in place, and press the key switch again to use.

After the Midea induction cooker is plugged in, the indicator light is all on for a drop, and it is all off immediately, and the switch does not work may be caused by a variety of reasons. Here are some possible reasons:

1.Power failure: If the induction cooker is not connected to the power supply properly or the power supply is faulty, it will laugh and cause the indicator light to turn off when it turns on, and the switch cannot be started.

2.Protection mechanism trigger: If the internal temperature of the induction cooker is too high or other abnormal conditions occur, the protection mechanism will be triggered. At this time, the indicator light will also turn off when it is turned on, and it will not start when the switch is pressed.

3.Control board failure: If the control board of the induction cooker fails, it will cause the indicator light to turn off once it is on, and it will not start when the switch is pressed.

4.Poor line contact: If the internal circuit of the induction cooker is in poor contact or loose, it will also cause the indicator light to turn off as soon as it is on, and it will not start when the switch is pressed.

In view of the above problems, you can try the following solutions:

1.Check whether the power supply is properly connected to the bucket to the induction cooker, and check whether the socket is working properly.

2.Wait for the inside of the cooker to cool down and try to start it again, or check if there are any other abnormalities in the cooker.

3.Try resetting the control panel of the cooker, or replacing the control board.

4.Check whether the internal wiring of the induction cooker is in good contact and reconnect the wiring.

If none of the above methods can solve the problem, it is recommended to contact a professional maintenance personnel for repair.

1. Flip the induction cooker, unscrew the screws at the four corners of the induction cooker 2, open the cover, find the control panel of the function key, check the capacitor 3, check the capacitor with special testing equipment, and show that there is power-on, which proves normal 4. After checking the control board, it is found that the chip of the control board is faulty 5.

6. Then put the circuit board back in place, and press the key switch again to use.

Check whether the 5V voltage of the control block of the control panel is normal, and whether the fuse resistor of the 5V series of the control block is open, and burn 4

7. European insurance is a common problem of Midea's induction cooker. It was fixed without spending any money. I don't understand, the problem is not clear in **, I hope it will help you.

Only open and check the internal circuit, if you can't overhaul yourself, send it for repair.

Have a nice day!

It may be that your voltage is too low or the voltage is unstable, and the current is too large instantaneously after plugging in the power supply, resulting in the voltage stabilization inside being burned out, and you need to take it to repair it When the voltage in our house was unstable before, it was good to take it to repair. . .

1. There is no reaction when the induction cooker is powered on (no power).

The causes of such faults usually exist in the following circuit units: high-voltage main circuits, low-voltage power supply circuits, and microcontroller circuits.

Second, the induction cooker cannot be turned on.

When this kind of fault occurs, the unfavorable factors caused by the use environment should be ruled out first, such as grid voltage, ambient temperature, etc. When it is determined that there is a fault in the induction cooker, focus on checking the protection circuit. Pot temperature detection circuit, IGBT temperature detection circuit, power grid voltage detection circuit, button circuit.

Summary. Hello, this is due to the fact that the bulb of the indicator light may be broken or the place where the bulb of the indicator light is connected is broken.

Midea's induction cooker is working fine, but the indicator light is not on. What is the reason.

Hello, this is due to the fact that the bulb of the indicator light may be broken or the place where the bulb of the indicator light is connected is broken.

It's not bright, can it be that the light is broken?

If it works normally, if the indicator light is not on, it can only be that the indicator light is broken.

It's impossible for the lights to break at the same time.

Quite possibly, because all the lights are on one line, and if one of the main lines breaks, all the lights won't come on.

Tell me how to look it up.

This can only open the shell of the induction cooker to check whether the wiring connecting the lamp is broken.

I opened it, I didn't see a breakpoint, and the connecting lines I measured were all connected. You told me that the line was about the lights.

You can only measure one line at a time.

It's not that the line is broken, you just tell me how it works.

Do you take a look at the display of the lamp is not a problem?

The display screen and the lights are not on!! You'll tell me how to control it.

What's the control method here?,It's obviously a broken circuit, brother.。

That's the display is broken.
