I recently received a safety notice from my institutional Health and Safety Department about Corning PC420 hot plate stirrer. Apparently, there is a risk that the plate will start heating by itself even if the heating button is turned off. I did a quick web search and this problem could be caused by a defective microcontroller sending a heating signal while it should not. More info is available here.
This instructable will show you how to disconnect the heating element of a Corning PC420 hot plate stirrer and convert it into a stirring plate with no heating function.
