=>I just bought a large GE toaster oven. The last step in each cooking =>instruction is to unplug the oven.
We have a B&D toaster oven that has, as of this morning, failed to burn down the house.
Manufacturers connect the neon indicator to the heating-element circuit. This tells us what? The element is energized and very hot. Do not touch. Gee.
When baking, the thermostat cycles on and off with the indicator winking and blinking dutifully in step.
Close the door after you have removed a baked good and the oven keeps right on cycling on and off until the smoke alarm goes off (too late) or you turn the temperature control (thermostat) down to "off."
How about a green indicator somewhere on the panel that tells you "All's well. I'm not doing anything now, but I'm ready for your next command."? If that indicator is not illuminated green you'd better look and see why. Nah. Too expensive! But you could leave the neon "I'm Hot" indicator on the panel, too!
Much cheaper to add ..."unplug the oven when through cooking" at the appropriate places in the manual.
I'm not a lawyer, but I was a technical writer and editor for 20 years in the electronics/aerospace game. Ink is cheap--lawsuits not so cheap.
