We have two of these PRC built Tefals, the design and finish makes it hard for me to let go and bin them - and my inbuilt genetic urge to repair everything.. One will flick the breaker after it has almost finished toasting, that looks like a carbon trail earth leakage somewhere or faulty thermistor, still debugging. The other was easier to diagnose, it just will not stay down, the power relay points are not being engaged as the whisker has broken off, so no power to the cct board that feeds the electromagnet.. Torx tamper proof screws hold all these ones together, be careful to wiggle the (toaster..) body until it releases. The older one was easier disassembled, newer have little tabs from the stainless body down into the toasting chamber, so be careful not to bend them, and to align them when putting it all back together.
