I was cooking some food when I noticed a burning plastic smell and some smoke coming out of the knob, I let it cool down, and when I turned it back on, there wasn’t any smoke but the burning smell returned, is the plate damaged, or is it some stuck food being burned?
The burning plastic smell seems to be coming from the plate, even when it is dissassembled like this, i can smell it from the centre.
It could be the heating control element. If that’s broken, the heating element can easily overheat and damage the coating on the metal plate. It will also melt your wiring and eventually your whole house, potentially even the whole world. I would buy a new one (or fix it, if that’s your fancy)
