The beauty of the electromagnetic oven does not heat what is the problem, professional answer to understand
I wonder if you are new, or old, should be the power pipe problems.Protection system is out of order, and then there is no pot when the induction cooker does not turn on, otherwise it will burn out the power tube easily. Power pipes are more likely to go bad.
The electromagnetic oven repair inspection pot, is an easy job to do things to proficient, but beginners often feel difficult to find, and easily mistaken for MCU damage. In response to this situation, I have accumulated a little experience that we usually hear, but also in order to be able to communicate with you more, and raise their own technical level.
There are 6 reasons for the non heating of induction cooker:The main circuit is not vibrating, check the 0.3uF capacitor, the big wire coil, the power tube.Power sampling resistor 470 Euro change value.Compare the sampling circuit fault, check the LM339 and its additional peripheral resistance and capacitance.Current detection circuit fault, check the 5.5H transformer and 4 rectifier 4148 diode, 103J capacitor, to about CPU, 10K resistance.CPU bad, no pulse signal output.Excitation tubes 8050 and 8550 are bad.
