The first thing to do is to determine where the real cause of the round induction cooker failure is.

In general, if the round induction cooker is not powered on or burned out, it is not necessary to determine a reason, just replace the motherboard, and then take the broken motherboard to carefully study and analyze the main reason. But usually the performance of some induction cookers is an adaptation problem: obviously the factory is aging very well, and the result is that the customer's heating is not ideal, or the gap heating, or the protection of burning, usually such problems should be carefully looked at the fault code display of the induction cooker. Check this manual for fault codes. The problem displayed by the fault code is generally in the use environment, such as the voltage environment, and the collocation of pots and pans.

A tool that must be carried to judge the failure of the round induction cooker.

A small magnet. Small magnets can help determine if the pot will fit. The pots used by the round induction cooker are pots with high magnetic permeability. If the magnet can attract the bottom of the pot, it means that the pot is fine; if the pot cannot attract the magnet, it means that the pot is not suitable. It will cause the frequency of the induction cooker to increase and the power to increase at the same time. The temperature of the IGBT inside the round induction cooker is too high. If the temperature is near the high temperature protection critical point of the IGBT for a long time, the induction cooker will appear intermittent heating, and the IBGT will be burned after a long time.

When judging the failure of the round induction cooker with a multimeter with a power test, first use the multimeter to test the mains supply voltage of the environment where the round induction cooker is used. If the voltage is within 10% of the positive and negative deviation of 220V, it means that the voltage is normal. If not, then If there is a problem with the voltage, you can check the cause of the voltage imbalance and start from the substation.

The external faults caused by the mismatch of the pots are generally: no pot, low power, high power. If the power is too small or too large, the temperature in the round induction cooker will rise, and the IGBT will be in a high load state for a long time, which is prone to failure.
