Joyoung induction cooker turns on a drip, the power indicator flashes, and the indicator light is al

Induction cooker function flickering can not be selected to exclude:

1) The indoor voltage is unstable, and there is surge protection.

2) The voltage is unstable, and e3 or e4 appears

3) The furnace temperature is too high, and E2 or E6 appears

Joyoung induction cooker turns on a drop, the power indicator flashes, the indicator light is always on after pressing the power button, the internal button is broken if it is not turned on, and the fault can be solved by replacing the button, the specific operation steps are as follows:

1. Turn on the power supply experiment, no power failure.

2. Remove the fixing screws at the rear of the induction cooker.

3. Open the back cover to expose the key circuit board.

4. Remove the button plate.

5. Replace the keys by welding.

6. Resume the post-installation experiment and work normally.

If not, go to the local Joyoung after-sales service to change a display board, it is 21es10, the light board is 58 yuan, see if you can charge you for maintenance!

After cleaning the keying board, check whether the capacitor has leakage and whether there is leakage between the pins of the manifold block. View the original post

Joyoung. The induction cooker turns on a drop, the power indicator flashes, the indicator light is always on after pressing the power on button, the internal button is broken if it is not turned on, and the fault can be solved by replacing the button, the specific operation steps are as follows:

1. Turn on the power supply experiment, no power failure.

2. Remove the fixing screws at the rear of the induction cooker.

3. Open the back cover to expose the key circuit board.

4. Remove the button plate.

5. Replace the keys by welding.

6. After resuming the installation of the sliding pin, the experimental finch let the digging and work normally.

Please check whether the power cord of the machine is installed in place, or try to change the plug, if the machine is still faulty, the machine problem can be moved to the Joyoung after-sales service department for maintenance, and the link to Joyoung customer service center is scattered.

It can be located in the nearest after-sales service outlets, Joyoung's customer service is humble.

Joyoung induction cooker.

Plug in the power supply and all the indicators flash once, and then the switch indicator lights flash in Bi Sui, but it does not work because the regulator capacitor of the circuit board is cracked and damaged, and the dust bend can be restored after being replaced, the specific operation steps are as follows:

1. Open the back cover of the induction cooker.

2. Remove the screws of the internal heating plate.

3. Open the hot plate and find the capacitor.

4. Replace the capacitor on the circuit board.

5. At this time, resume the installation experiment of parts and return to normal.

In this case, if there is no response when the power button is pressed, it is likely that the power switch of the induction cooker is damaged, which leads to poor internal contact; For the touch type induction cooker, after the start-up "drip", if there is no response when pressing the power button at this time, it is most likely that the touch pad has failed; There is also a possibility that the main control IC chip in the induction cooker is damaged, which will also occur. How to solve the problem of no response after the induction cooker is turned on 1, before using the induction cooker, you need to read the manual very carefully, and operate in accordance with the manual, after connecting the power cord, press the on/off key of the power supply, and then press the function key, only in this way, the induction cooker can work normally. 2. Check the tact switch on the key board, if there is a bad conduction, the tact switch needs to be replaced.

3. The induction cooker of the touch board does not respond after the "drop", and it needs to be inspected and replaced with relevant parts under the operation of professional maintenance personnel. 4. For the failure of the main control IC chip in the induction cooker, the actual solution is to remove the chip and replace the new main control IC, which also requires professional home appliance maintenance operators.

Set the timer function, and a drip will appear when the timer operation is completed.

If the induction cooker is overheated, it will make a dripping sound, and if it is not dealt with in time, the induction cooker will start the protection function of automatic power-off.

If it is used for a long time, it will also make a drip sound.

Insufficient voltage used by the induction cooker will also cause the induction cooker to make such a sound.

Joyoung induction cooker plugged in the power supply all the indicators flashed, and then the switch indicator lights flashed, but it did not work because the regulator capacitor of the circuit board was cracked and damaged, and it could be restored after replacement, the specific operation steps are as follows:

1. Open the back cover of the induction cooker.

2. Remove the screws of the internal heating plate.

3. Open the heating plate and find the capacitor.

4. Replace the capacitor on the circuit board.

5. At this time, resume the installation experiment of parts and return to normal.

This is because the induction cooker circuit is faulty, and users are advised to repair the power supply circuit.

After the induction cooker is plugged in, the computer board is directly energized and there is no switch. When you press the switch of the induction cooker, you only notify the computer board to start the heating program and let the heating circuit of the induction cooker work. When the computer board is first plugged in, it will generally emit a short sound, indicating that the computer board has entered the standby working state, waiting for user instructions.

Check whether the DC 18V and DC 5V voltage of the switching power supply part are normal. In particular, 5V is very important, and the controller of the induction cooker, also known as the single-chip microcomputer, controls the start, stop, detection and operation of the entire induction cooker, and the operation and display of the panel must use this voltage. Most of the 5V generation is obtained by the rectifier filter output of the switching power supply through a 7805 three-terminal voltage regulator with a shape similar to a triode such as 9014, and the failure rate of this three-terminal voltage regulation is extremely high.

After starting, the machine flashes all is the detection indicator, the switch flashes and needs to be touched to turn on the switch, select the function to use after opening, if the induction cooker does not work, you can exclude it according to the following.

1) The indoor voltage is unstable, and there is surge protection.

2) The voltage is unstable, and e3 or e4 appears

3) The furnace temperature is too high, and E2 or E6 appears

This is generally the induction cooker buttons are sticked, resulting in the induction cooker CPU can not get the boot instruction, the simple point is that the button is broken, if you have strong hands-on ability, you can better display the buttons on the board, or find a master engaged in the maintenance industry to repair for you, the cost will not be too much, generally 15-30 yuan, this depends on the consumption of your location.

Is it useless to press all the buttons, yes, there may be a little leakage between the buttons, you can disassemble the circuit board with a hair dryer to blow the circuit board inside for ten minutes, and then power on! Due to the poor working environment of the induction cooker, the connection between the button board and the motherboard will have poor contact for a long time, check whether the connection is broken, and whether the plug and terminal of the connection are rusty!
