The weight that closes the circuit has slipped entirely off the top of the circuit due to Alice's wrestling with the cover.
Fig 2: door hinge
From jack knife
the wire sticking out is part of the lever that hooks to the door spring. it needs to go back through that loop on the oven door.
Fig 3: foiled again
From jack knife
winding this strip of foil around the hinge joint to force it into alignment didn't fix the problem.
Fig 4: collaboration
From jack knife
ultimately this didn't fix the problem, but it's a nice action shot.
Fig 5: the real problem
From jack knife
this is the switch that needs to be adjusted. The two copper strips make contact and complete the circuit when the weight is pulled back by the spring, which is deployed when the door is closed.
Fig 6: Jack removes spring
From jack knife
This is the spring that holds the oven door closed.
Fig 7: adjusting the circuit
From jack knife
doing this without unplugging the toaster first is stupid, btw.
Fig 8: Jack's injury
From jack knife
there's a spot of copper from the circuit melted into my blade. Alice felt nothing.
Fig 9: after the circuit breaker popped
From jack knife
we continue testing. and remembered to unplug the toaster.
Fig 10: everybody wants a rock to wind a piece of tape around
From jack knife
electrical tape binds a small rock to the plastic weight that closes the circcuit when oven door is closed.
Fig 11: beginning of test
From jack knife
oven starts correctly as Alice pushes button. Rock weights down circuit.
Fig 12: test fails
From jack knife
the light (and heat) should have gone out when the oven door was opened. circuit needs adjustment.
