    Electric Range Failure Modes

    Ranges and cooktops lead the equipment statistics for home cooking fires. This course shows how to tell when a range actually failed and when it only burned.

    You will learn:
    - How a range is built, system by system: elements, surface controls, the oven, self-clean, electronic controls, and the supply terminal block.
    - The failure modes: welded relay contacts, element sheath rupture, high-resistance connections, and self-clean overheat.
    - The evidence each one leaves, and how to prove a range was operating normally.
    - How to work burned ranges case by case in a 3D examination lab, and control board faults on a schematic bench.
    - The examination protocol, the recall lookup, and the limits of what your opinion can claim.
