The serviceable components of the oven are now accessible.

This reveals the other sides of the heating elements, the timer and thermostat circuitry, as well as the main power input.

The oven pulls an estimated 1150w at full draw. There are no fuses or safety mechanisms.

The timer knob functions as an on-off switch to the rest of the oven. There is no variability to the amount of current flowing through the elements, they are either on or off, controlled by the bimetal thermostat above the timer knob. See the schematic PDF for more information.
