    Hi,

    I got a Siemens EH777501EX/01 Induction Cook Top.
    The other day, the right side stopped working. It turns on, but the activation magnet doesn't seem to work.
    After opening it up, I say that the right side pcb, Cerler ELIN-DCHA ADV VC26, had a burned "square".
    What type of component is this? A fuse? I can't find any information about the pcb online. If it's just a bridge I can strap it.

    The working left side pcb, Cerler ELIN-IZDA ADV v26 shown for reference.

    Thanks,
    Fredrik

    Whatever it was failed spectacularly.
    Additionally, the currents involved may prove to be a little difficult to work with, and bypassing components could lead to much more costly damages elsewhere.

    Perhaps one of the other guys can suggest what the component used to be.

    HI and welcome to EP :)

    definitely looks like a fusible link
    and since it has blown so, as gryd3 said, spectacularly, you should be looking for a fault past that point that caused the excess current to flow and blow the link

    I don't know what caused this spectacular (thanks Gryd3) fault, but often moisture gets in from pots boiling over on the stovetop and fries the board.
    The second carbon mark above it in the first picture looks strange.
    Would bridging with a small path of solder be enough to suffice, or better to replicate the original link with the same size and material? (That is, after the fault is determined)
