What are the reasons why commercial induction cookers do not heat?

External natural factors and conditions:
1. Grid voltage: Appears when the voltage is high or below the operating voltage range of the induction cooker. The nature is forced standby. And display the fault code (if there is a display function).
2. Internal overheating of commercial induction cookers: the triggering temperature is mostly between 90 to 95 degrees, and the release temperature is between 60 to 70 degrees. The nature is a temporary shutdown and a fault code is displayed. If the temperature reaches 110 degrees Celsius, the power is forced to shut down. (When overheating, it is easy to be mistaken for an "intermittent heating" fault.)
3. Surge: Surge is a kind of spike pulse with greater harm generated when the voltage in the power grid rises or falls instantaneously. Excessive surge will generally be discharged by varistor, and only some small surge will trigger surge action. The nature is a short-term pause. If the power grid is outdated and there is poor contact, there may be occasional pauses. (This type is generally difficult to detect or mistakenly assumes that the power of the induction cooker decreases.)
4. Pot over temperature: also known as "anti dry burning", the trigger temperature is 280 to 300 degrees Celsius, and the release temperature is 70 to 80 degrees Celsius, which is a forced shutdown.
