      Passo 1 — Rupture of the heating element

      A common failure is a broken heating element. If the toaster does not heat up, or if the lever does not stay down (1), check the continuity of the resistance circuit with a multimeter.

      Passo 2 — Damaged heat resistor

      When the damage has been located, the repair can be carried out. The heat resistor is made with an alloy of nickel and chrome, and nichrome (*1) that's impossible to weld with ease. It is therefore necessary to create a connection either with a piece of wire as a strap, or with the crimping sleeve (*2)

      Passo 3 — Bipolar switch

      Since the power of the device is between 600 and 1200W, the bipolar switch (marker 2) must support a current between 2.5 and 5A (1), which is important given its small size. When contacts deteriorate, their resistance will increase and the heat will dissipate in the switch and eventually burn them.
