Induction cooker can not sense the pot
See if 300V is normal or normal. You take the big resistance down and measure a change. As long as it's over 8K, if you don't change it, change the LM339. Change with AK339
I can not induction cooker induction cooker fault into the following three categories:1, 300V filter capacitor is not good, causing the main voltage is too low, so that the voltage detected by the synchronous circuit is not normal.2, synchronous circuit of high power resistance deterioration or open circuit, resulting in abnormal detection circuit.3, PWM pulse signal is abnormal and not check pot.
Your friends, this is likely to lead to the electromagnetic oven inside damp, clean up debris inside you open it into the dust under the sun sun sun installed try, can usually be solved.
