Reasons why the induction cooker does not heat What to do if the induction cooker does not heat

1. The reason why our common induction cooker does not heat up is that the pots and pans used are incorrect. When buying an induction cooker, the salesperson will tell you that it is best to use a special pot or iron pot for an induction cooker when using an induction cooker. The use of iron pots is to better prevent the radiation of the induction cooker from spreading outward, and the special pots and pans are mainly more suitable for the use of the induction cooker.

When the pot is not suitable, the induction cooker will constantly beep and will not heat up.

What to do if the induction cooker is not heated: in this case, to solve the situation that the induction cooker is not heated, the pots can only be replaced again, the general flat-bottomed iron pot is more suitable for the use of induction cooker pots and utensils, and the special pot for induction cooker is suitable for the pots and pans of the induction cooker, and these two pots can be used when replacing.

2. When the induction cooker is not heated, you can see if the sensor of the induction cooker is open or short-circuited, which will force the induction cooker to shut down, and the induction cooker will not be in a closed state when the induction cooker is not troubleshooting, and the button will not play any role, at this time the induction cooker will show a fault**.

What to do if the induction cooker is not heated: At this time, when the induction cooker is not heated, it is necessary to know the meaning of the induction cooker, so that we can clearly know the cause of the failure of the induction cooker, so as to repair the problem.

3. The IGBT overcurrent protection of the induction cooker will also cause the induction cooker not to heat, when the current of the induction cooker is too strong, the overcurrent protection device of the induction cooker will start, and the overcurrent protection will reduce the power of the induction cooker or directly stop the induction cooker from working. This type of situation can lead to regular intermittent heating of the induction cooker.

What to do if the induction cooker does not heat: in the state of overcurrent protection, the induction cooker does not heat up, it is necessary to extend a period of time and then start the induction cooker, when the current of the induction cooker returns to normal, the induction cooker will automatically return to normal when in use.

4. If the voltage in the induction cooker is too high, it will trigger the overpressure protection of the IGBT tube, and the induction cooker will be forced to reduce the output power in the overpressure protection state, and the voltage of the IGBT electrode will also be reduced accordingly.

What to do if the induction cooker does not heat: In this case, the induction cooker does not heat up, and the induction cooker needs to be suspended and the induction cooker is used again after a period of time, and at the same time pay attention to the voltage of the induction cooker to avoid the overpressure protection of the IGBT tube triggered again if the induction cooker voltage is too high.

Take it and fix it, don't tear it down and fix it yourself.

When the cooker is not troubleshooting, it is turned off, and the keys do not play any role, and the cooker will show a fault**. At this time, when the induction cooker is not heated, it is necessary to know the meaning of the fault shown by the induction cooker, so that the cause of the failure of the induction cooker can be clarified.

Re-replace the pots and pans used, the general flat-bottomed iron pot is more suitable for the use of induction cooker pots and utensils, induction cooker special pots are suitable for induction cooker pots, and these two pots can be used when replacing.

In the state of overcurrent protection, if the induction cooker is not heated, it is necessary to extend a period of time and then start the induction cooker, when the current of the induction cooker returns to normal, the induction cooker will automatically return to normal when it is in use.

Use and maintenance:

1. Install special power cords and power sockets. Due to the high power of the induction cooker, the power cord and socket must be configured according to the power, usually the copper core wire that can withstand the current of 15A should be selected, and the socket, plug, switch, etc. used should also meet this requirement. Otherwise, the high current when the induction cooker is working will cause the heating of wires, sockets, etc., to burn and short-circuit.

2. The induction cooker should be placed steadily. If one foot of the cooker is in the air, the gravity of the pot will force the stove to tilt and the food in the pot will overflow. If the stove surface is not evenly placed, the micro-vibration generated by the pot can also easily cause the pot to slide out and cause danger.

3. Ensure that the air inlet and outlet holes are unobstructed. The induction cooker in the work heats up with the heating of the pot, so the induction cooker should be placed in the air circulation, and the air outlet should be more than 250px away from the wall and other items to ensure that there is no object blocking the inlet and exhaust holes of the furnace body.

2. Do not sit in the pot during the test operation, and at the same time connect the 25-watt incandescent lamp in series in the power supply circuit of the induction cooker to prevent the internal short circuit from exploding the machine, which will expand the fault. At this time, observe the brightness of the bulb, if the brightness is normal, it means that the inside has been short-circuited. If the bulb is flashing, the oscillation circuit is working almost normally.

3. To judge whether the oscillation circuit is working, use a buzzer and a light-emitting diode in parallel and put it on the stove surface to effectively observe the induction cooker. The flashing LED indicates that the cooker is working properly.

4. Open the cover to detect the resistance of each way, starting from the gated tube, including the rectifier bridge stack, high-power resistance, 4UF, etc., try to measure with a pointer multimeter, and the measurement can be carried out with one end of the solder absorber disconnected from the component.

5. Common vulnerable components are: high power and high resistance, capacitance becomes small or out of capacitance, resistance becomes large or open circuit, and LM339 is damaged.

6. The damage of the key is very simple, and it is likely to be caused by leakage due to moisture.

7. Many of them are caused by power sockets, try to replace power sockets after repair.

Induction cooker internal reasons cause no heating: including temperature sensor 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.

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 force the power off 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.

There is also a kind of pot to prevent dry burning, and the induction cooker will also be forced to cut off the power.

The induction cooker does not heat up, which is one of the most common problems we encounter in the process of using the induction cooker, if it happens often, the machine is malfunctioning, and occasionally it happens because of improper operation. This requires us to master a certain amount of knowledge, when there is a problem with the induction cooker, you can first check the cause of the problem, and it is also convenient for you to repair it in the future.

Internal reasons why the induction cooker does not heat up.

The voltage is abnormal, and the integrated circuit LM339 and the driving circuit cannot work normally, resulting in the driving voltage added to the power tube is not enough to make the power tube turn on.

2.The vertical vibrillator of the power tube overvoltage protection circuit element is abnormal, which makes the overvoltage protection circuit malfunction, shorts the PWM pulse control voltage to the ground, and makes the driving circuit unable to output the driving voltage, resulting in the power tube no driving voltage in the cut-off state.

3.The surge protection circuit element is abnormal, so that the surge protection circuit acts, and the driving impulse voltage is shorted to ground.

4.The overcurrent protection circuit element is abnormal, and the driving excitation pulse is pulled down to the ground potential.

External reasons why the induction cooker does not heat up.

1.When the induction cooker can not be heated, it is not necessarily caused by the abnormality or failure of the induction cooker, because there are a large number of protection circuits designed in the induction cooker circuit, generally there will be seven or eight or even more, and these protection circuits are set up to prevent the failure of the induction cooker caused by various external natural factors such as power grid and temperature, as well as various sudden abnormal phenomena inside the machine. Before overhauling the induction cooker, you should carefully analyze whether the induction cooker is a real fault or a false fault.

2.Finally, we have to go and see if the plug has fallen off, if we accidentally make a small mistake? Is the automatic switch or fuse open?

Is the pot used appropriate? Is the pot placed on a flat plate** part? Is the diameter of the bottom of the pot less than 12cm?

Is the wok not left the stove after use? Is the ambient temperature high? Are the suction and exhaust ports blocked?

Make the cavity fiber use a thin iron pot shabu-shabu, the soup is too thick or the moisture is not enough. Whether the bottom of the pot used is uneven, or the center is more than 2mm hollow.

The solution to the induction cooker not heating.

When the plug is plugged into the power supply and we don't hear a D sound, we have to start from the source. First, cut off the power supply of the induction cooker, and then use a current pen to test whether the socket interface of the induction cooker is damaged. If the socket is intact, we will check the power cord of the induction cooker to see if it is a problem with the power cord.

If there is a continuous short dripping sound and the machine stops after a long time, then check that the pot used is suitable. The cookware should be placed flat on the platform. The diameter of the bottom is generally not less than 12cm, etc.

If the machine is suddenly shut down during use and makes a dripping sound, you need to check whether the surrounding environment is too high, and whether the suction and exhaust holes of the induction cooker are blocked by foreign objects and cause the internal temperature to rise.

There is also to check whether the function key is pressed wrong, whether the water in the cookware is boiled dry, and whether the pot is unequal. In addition, we still recommend that it is better to find a professional to deal with the problem of the induction cooker, and the loss will outweigh the loss if the internal parts are damaged by blind self-repair. The above is the reason and solution for the induction cooker not heating that we introduced to you today

1. The reason why the induction cooker is not heated: the induction cooker will not be heated after being used for a period of time, if the above reasons are excluded, then it is likely to be caused by the aging of the internal circuit of the induction cooker. At this time, the induction cooker needs to be repaired, and the specific operation method is as follows:

First of all, turn off the power, then open the case, unscrew the fixing screws of the main control switch with a screwdriver, remove the main control switch, and then gently break the main control switch with your hand to observe whether the spring is damaged, if it is damaged, you need to replace the new main control. Then, the control board is overhauled according to the following steps.

2. How to repair: first check the fuse on the motherboard to see if it is blown or not, if the fuse is blown, it means that the circuit has been short-circuited, resulting in the host can not be heated normally. Next, check the thermistor on the motherboard to see if it has been broken down or opened.

Finally, check the pins and wires on the motherboard to see if there is any false connection, and if so, reconnect to ensure that the line is unobstructed.
