2, the circuit heat dissipation performance is not good, so that the thermal protection is frequently opened, you can change in the ventilated place to cook.
3. There is something wrong with the oscillation capacitor in the PWM wave generating circuit. Replace it.
4. The power plug is a little loose, which may also cause this phenomenon.
5. Turn on the heating mode and try it at the maximum gear. There may be something wrong with the mode.
6, CPU has a failure, which is equivalent to only replace the motherboard.
For the induction cooker this heating for a period of time is not heated, the usual reason may be the main return passing current or power tube C pole overvoltage protection. (Through the detection of the main circuit power, the whole bridge whether there is leakage phenomenon; Is there a problem with the current of the potentiometer VR1? Is the power supply voltage of 5V, 18V and 300V normal under standby state?
