We have a electric stove which looks like it was designed in the late 1980s or early 1990s, and probably was made in ~1995.
It has physical knobs that you turn around to change the heat for each plate. Four plates. The plates are metallic and separated from the white "backplate". (That is, there is a height difference. It's not one of those fancy, modern stoves with a fully flat glass plate which were just starting to appear in ~1995.)
Anyway, a family member mentioned recently that she thought that it had started emitting heat in the front and generally "around" the designated metal circles. I have also noticed this, and verified it today by touching it with my finger, quite a bit away from the actual circle, and it was super hot. Not just a little warm. Really hot.
This seems like it's somehow got damaged. Is this a common problem? Is it dangerous? Perhaps critically lethal? Will it blow up any day now? Will it start electrocuting us soon?
I tried to search for this online but found nothing, but that says nothing because I never find anything no matter what I search for.
Would really prefer to not have to deal with buying a new stove or even have this one replaced. Perhaps it's always been like this and I've just not thought about it before she had to mention it?
