Hello. There is a Fagor 5ift-22 s hob. 2 burners it has induction, 2 ordinary ones with heating. Symptoms are as follows: when the induction is turned on, the machine immediately knocks out. When you turn on the other two comforts, everything is fine. What was done: replaced by PWM, power transistors. The board is also the power supply unit IND5G-CF. Conventionally, the board can be divided into 2 parts: the power section, which controls the comforts, and the auxiliary, which controls the control board, which is connected separately. There is also a third board, which is responsible only for the comforts with a heating element. The control board is powered by an auxiliary low power supply. So, in order for the induction comforts to turn on, the control board must supply 12V to the relay, which closes the circuit between the phase and the diode bridge. I can't tell you the model of the bridge now. I soldered it separately and called it with a tester, everything is in order, but I'm not 100% sure. The question is the following. If this is not a diode bridge, then what else can close after it? After the bridge, all the diodes, power resistors rang, everything is ok. Thanks in advance, and if I wrote something wrong, please correct it.
