Cheap replacement for the original power regulator

I had the problem that a dual-circuit board my privilege cooker could no longer provide from small to big, what happens by lightly turning the control knob. After consulting an electrician and its reference to any existing order problems and relatively high spare part and repair costs, my wife would rather have a new stove. But equal to 600, - Euro for the equivalent stove with excerpts and large oven to spend because then came but the avarice and the realization that you could also get the spare parts themselves and install if necessary. After removing the oven, I noticed that you only pull the plug on the Ceranfeldes and remove a diaphragm had and would just let the controller, obviously the defective part (!?), Replace. Off (power is incidentally also a great idea! ;-)
So searched the internet for the number, what problem presented itself, there really was 50.55051.100 provided for the stove, the component. In spare land, it turned out that the objective controller with many herds is compatible. Amazon's gave the seller as well, so for less than 12, - Euro ordered the part and after two days the stove was running again as the first day. The replacement part has the same dimensions, contact arrangements and the same function as the original part. I would always buy it back and even with this supplier.
