Why does the high-power induction cooker suddenly stop heating when it is running?

Here's the explanation of why high-power induction cookers suddenly stop heating during use:

1. Internal reasons for the lack of heating in high-power induction cookers include issues such as temperature sensor circuit breakage, IGBT (Insulated Gate Bipolar Transistor) short-circuit protection, IGBT overvoltage protection, and IGBT overcurrent protection. When these problems occur, simply waiting for a while and then restarting the cooker should be sufficient.

2. External environmental factors can also cause the induction cooker not to heat. If the voltage of the external power grid is higher or lower than the working voltage range of the induction cooker, the internal protection mechanism of the cooker will forcibly cut off the power supply to prevent heating. Additionally, if the internal temperature of the induction cooker becomes too high, the temperature alarm mechanism will also forcibly shut down the heating function. Furthermore, if a pot is absent or dry, the induction cooker will shut off power as a safety measure.

3. Intermittent heating of the induction cooker may occur due to overcurrent protection of the IGBT. Overcurrent protection can result in a forced reduction in output power or a direct pause, followed by a delay before restarting into working mode. This protection action may lead to periodic interruptions in heating.

4. Sudden cessation of heating in high-power induction cookers may also be due to surge protection. Surges are dangerous peak pulses that occur when the voltage in the power grid system rapidly rises or falls. Large surges will be discharged by varistors, while only small surges will trigger the action of surge current protection circuits. The protection essentially involves a brief pause. Irregular interruptions may occur if the power grid is old or if there is poor contact.

5. If the induction cooker stops heating without any apparent reason, it could be due to the overtemperature protection of the pot. This type of overheating protection, also known as "dry burning protection," triggers at temperatures between 280 and 300 degrees Celsius. Once the temperature reaches 280 degrees Celsius, the cooker will automatically shut off, and it will reactivate once the temperature drops to 70 to 80 degrees Celsius.
