    It’s definitely not required for ovens. You can just open the oven. Source: previous oven (1950s vintage) didn’t have one.

    Pretty useful though, and pretty important on microwaves too since you can’t safely open the [microwave] oven while it’s running.

      You can open it but you every time you do, you lose heat, which has to be compensated for by the oven. A window makes the process much easier. There wouldn’t really be measurable gains for a dishwasher

      How’s it not safe to open the oven while running? Just don’t touch anything without mitts and keep your face back.

          Yes. Microwave is short for “microwave oven”. I thought it was clear from context but I guess not.
