Your oven most likely don't use the hunk of pile, failure prone power electronics. The control circuits are floating on its own island. The highly reliable coil and core transformer provides the low voltage power source for the controls and the exceptionally resilient and robust relays operate the heating element.
Power electronics can fail without notice and often failing by sticking closed. The manufacturing cost streamlining embedded systems type design that incorporates power electronics just means power surge, poof and a total loss.
Light dimmers often fail by becoming stuck on full brightness. Cause? Power electronics, duh.
