I ask you for a circuit diagram for a stove (baking oven, cooker, in german: Backrohr) from Siemens (BSH):
E-Nr.: HE23U532 /01 FD 8079
Type: HTHE23
It is about 15 years old.
The display with the clock is operational. After switching it on, the left hand square lights up, but the right one does not. The LED on the small pcb is O.K., I tested that with the multi meter's diode tester.
The oven does not heat up.
The switch connected to the temperature knob works too. I do not fully understand the big switch connected to the 7-position knob on the left. That's why I need a circuit diagram.
It is quite likely that the stove experienced an overvoltage, as I tested an emergency power aggregate when it failed.
