Joyoung induction cooker JYC 20BS2 is energized, and the switch does not respond, what is the proble

The transformer is broken, and the transformer provides the CPU power on signal. The main thing is that you still plug the plug into the power supply when you are not in use, and the transformer is in working condition, and it will heat up and burn out after a long time. If you have a repair base, you can open the case, solder the transformer, and buy one according to the original model and replace it.

More than a dozen yuan. The maintenance department may be at least forty.

1: It may be that the key is broken, 1 yuan is enough to change the switch, this situation is more common, the general life of Joyoung's keys is 1 year;

2: It may be a problem with the transformer, but this kind of problem generally does not appear.

Speaking of the motherboard model, there are 3 power modules, and the one used in this version is R500390KR501

100 euros is 12a

There is also a 13003 with a driving triode.

or 13002 is 201

There is a power module that is 202.

You take a look. Which of these three should be.

The reasons for the failure to respond after plugging in the power supply may be: (1) Bad buttons (2) Loose wiring of the power cord (3) Power cord is not energized (4) Fuse blowing (5) Power crystal IGBT is bad (6) Resonance capacitor C103 is bad (7) Anion diode(8) Transformer is bad, no 18V output (9) The substrate component is breaking down to repair this kind of problem, first of all, we must distinguish the fault point, find out whether the power supply is bad or the power circuit is bad, the way to distinguish is to look at the 10A fuse, If the fuse is in good condition, it is generally a bad power supply or a bad CPU. It can be judged by measuring the fuse resistance of the power supply and the 5V power supply, the general power fuse resistance is off (most of them are 22 ohms) is the power supply problem, most of the key sail power supply IC is broken, find the 7805 to measure its input voltage and output voltage can also judge whether the power supply is normal.

To solve this problem, first check the power input circuit components of the induction cooker, such as power supply fuse, varistor, and 2 F AC filter capacitor, etc.

Measure whether the rectifier filter circuit components are damaged.

Measure whether the voltage regulation and oscillation circuit components of the switching power supply are normal, such as: the switching power supply voltage regulation oscillation thick mode chip, and the peripheral components of the chip.

Solution: Joyoung's induction cooker is returned to the factory for repair.

If the induction cooker is plugged in and does not respond, the following parts should be checked:

Bad keys; The power cord wiring is loose or the power cord is not energized;

fuse blowing;

Power crystal IGBT is bad;

Bad transformer. To repair this kind of problem, we must first distinguish the fault point, find out whether the power supply is bad or the power circuit is bad, the way to distinguish is to look at the 10A fuse, if the fuse is intact, the power supply is generally bad or the CPU is bad, you can judge by measuring the power supply fuse resistance and 5V power supply, the general power supply fuse resistance is broken (most of them are 22 ohms) is the power supply problem, most of the power supply IC is broken, find 7805 to measure its input voltage and output voltage can also judge whether the power supply is normal.

5V is normal and there is no power, most of them are bad CPUs or bad crystals. 10. Most of the fuse funder is IGBT breakdown or bridge pile failure, remember to check the filter capacitor of 5UF and the high-voltage capacitor when changing the power tube, maybe one of these two components is the real culprit of the bad rate tube. Also remember to check the 18V and 8550, 8050 two transistors, find out the cause of damage to the power tube and then replace, otherwise there is a great possibility of rework.

Summary. Hello dear <>

Joyoung induction cooker JYC-21GS02 switch indicator flashed and did not respond due to one of the following reasons: 1Power issues:

Please make sure that the power cord of the induction cooker is connected properly, the power supply to the socket is normal, and the power switch is turned on. 2.Induction cooker failure:

It may be that the induction cooker itself is faulty and cannot be turned on properly. You can disconnect the power supply, wait a few moments, and then reconnect the power supply and try to turn on the cooker again. 3.

Operation error: Please make sure you press the switch correctly, some induction cooktops may require a long press or multiple buttons to start properly.

Hello dear <>

Joyoung induction cooker JYC-21GS02 switch indicator flashed and did not respond due to one of the following reasons: 1Power issues:

Please make sure that the power cord of the induction cooker is connected properly, the power supply of the socket is normal, and whether the power switch is turned on. 2.Induction cooker failure:

It may be that the induction cooker itself is malfunctioning and cannot be normalized, so the lead is turned on. You can disconnect the power supply, wait for a while, and then reconnect the power supply, and try to turn on the induction cooker in the greenhouse again. 3.

Operation error: Please make sure you press the switch correctly, some induction cooktops may require a long press or multiple buttons to start properly.

Try to ensure the cleanliness of the furnace surface, just energize the induction cooker, etc., and press the switch for 2-3 seconds to slide it off. Joyoung JYC-21GS02 Power: 2100W Control mode:

I wish you a happy life! Sun Qi hopes that mine will be helpful to you.

Joyoung induction cooker JYC-21GS02 switch indicator flashed and did not respond because: 1Power failure:

Check that the power cord is in good contact and that the plug is not loose. 2.Line Failure:

Check whether the wiring between the furnace and the power supply is damaged or short-circuited. 3.Control Board Failure:

However, the blind trembling can be caused by damage to the control board, and the control and digging board needs to be replaced. 4.Switch failure:

The switch may be damaged and needs to be replaced. 5.Other failures:

It may be that the capacitors, inductors and other components are damaged, which affects the normal operation of the furnace.

What is the reason why my Joyoung JYC-21D induction cooker is plugged in and the indicator light does not light up and does not work?

The reasons for the failure to respond after plugging in the power cooker may be: (1) Bad buttons (2) Loose wiring of the power cord (3) Power cord is not energized (4) Fuse blowing (5) Power crystal IGBT is bad (6) Resonant capacitor C103 is bad (7) Anion diode(8) Transformer is bad, no 18V output (9) The problem of bad repair of substrate components should first distinguish the fault point, find out whether the power supply is bad or the power circuit is bad, and the way to distinguish is to look at the 10A fuse, If the fuse is in good condition, it is generally a bad power supply or a bad CPU. It can be judged by measuring the fuse resistance of the power supply and the 5V power supply, the general power fuse resistance is off (most of them are 22 ohms) is the power supply problem, most of the power supply IC is broken, and the 7805 can also be found to measure the input voltage and output voltage to clear the source can also judge whether the power supply is normal.

Extended information: The principle of induction cooker is the phenomenon of electromagnetic induction, that is, the use of alternating current through the coil to generate an alternating magnetic field that changes direction, and vortex currents will appear inside the conductor in the alternating magnetic field (for the reason, please refer to Farasun's law of electromagnetic induction). This is caused by the vortex electric field pushing the carriers in the conductor (the ones in the pot are electrons and not iron atoms); The Joule heating effect of the vortex current heats up the conductor and thus heats up.
