Hello!
I have an old siemens kitchen (don't know the model but it's very similar to siemens hb12320gb). It has four stoves (not glass, solid ones) and each one of them has 4 cables connected to it (I believe that since each switch has 3 positions, the 3 cables are the phase carriers that are connected to 3 different resistors and the 4th one is neutral).
The problem seems to be random since it does not occur at every attempt (sometimes the fuse opens some times it just works normally).
I'm sure though, that the small stove always triggers the panel fuse to open and cut the current when I'm switching it on.
Also, the grounding system is two large pieces of metal, connected directly below the stoves (One piece of metal for the 2 big stoves in the back and another one for the stoves in the front).
What I tried so far:
1) I disconnected the grounding cable from the grounding system (because it was very short in length and I couldn't open the chassis without over-stretching the wire) and I noticed that switching on the small stove was not triggering the fuse panel to open anymore (I also tried all the other switches as well and everything worked normally). Though later it started triggering again, so this observation was not helpful.
Anyway, I thought that maybe one of the stove cables was shorted with the chassis, and this was why it was triggering the fuse to open. So, I used my multimeter to check for shorts between each stove cable (4 cables * 4 stoves = 16 total) and the ground but I didn't find any shorts!!!
2) Then I tried to find shorts between each cable that is connected to the small stove switching mechanism, and still I did not find any shorts, except the ones that are supposed to be shorted (you can see the connections in the switching mechanism are differentiated by rectangles, so cables that are on the same rectangle are supposed to be shorted, I'm not sure I'm just assuming it but its probably correct).
So what else can I try? Do you want me to send you pictures as well?
I mean, it's just 16 cables connected to 4 different switches that lead to 4 different stoves (resistors), so how hard could it be to fix it?
I'm an Electrical & Computer Engineer for gods shake, and I can't fix my damn kitchen...
Could it also be that nothing is shorted, but maybe some of the resistors are damaged so that the stoves sometimes draw more current than they ar supposed to draw and this current happens to be big enough to open the panel fuse?
Thank you!
