I have just succesfully changed torpedo shaped component cable tied in to the wiring loom.it had 2 white and 2 blue wires coming. BUT...
I disconnected another cable next to the above with three terminals. The first one is attached to the fan. The secong is attached to the "mechanism" behind oven's button. The problem is the third terminal, which I don't know where to connect it.
