SHORTING SEALED ELEMENT ELEMENTS
I once had a Frigidare Electra-Clean range in my shop for testing that had been sitting outside for over a month and enough moisture had gotten inside the bake element that when I was preheating the oven I heard this strange sound like steam escaping. I opened the oven door and everything looked normal, bake element nice and red hot, then closed the door and as I turned away from the range there I heard this loud explosion and the oven door blew open with enough force to hit me in the butt. I am very lucky that it didn't do this a moment earlier as I may have been blinded. I have also heard from many customers over the years that have had surface elements fail violently and shooting sparks and even welding cookware to the element in the process. This is way it is important not to use electric elements on the high heat setting for long periods of time if large portions of it are glowing red hot. If this is occurring you either need better [ flat ] pans or the elements are warped and should be replaced. This is one reason that appliance manufacturers have been pushing smooth-top ranges as they are much safer in the hands of stupid consumers. I personally like the Calrod type surface elements but they do need to be used with a bit of common sense.
On cleaning Items in the self-cleaning oven, I have always done this and always leave the racks in place. In fact most SCOs ever made either suggested leaving the racks in or said it was permissible if you didn't mind the initial discoloration that occurred from doing so. I know that there are some newer SCOs that tell you to take the racks out or even have an interlock that forces you to remove them, but I would never buy such an oven. SCOs are wonderful for cleaning porcelain on steel cookware and drip bowls, cast iron cookware, many aluminum pieces and one of my favorites Corning-Ware.
