Hi, guys. I have a thermal shutoff in an electric storage heater which failed suddenly with burn marks on one side and onto the connecting wire (pic). I ordered the replacement component and connected it in, all the wire cut back and cleaned, etc.
As soon as I turned the heater back on, it popped again, this time scorched on both sides.
This is the first component in the whole circuit - the live wire comes straight from the wall and into this. There's nothing before it that could be failing/missing.
In the picture, below/off screen is the heating elements. The face of the switch is exposed to them in order to sense the temperature. It's all behind a heat shield - the burning is definitely from it "blowing" and not from the heating element.
Any ideas?
Thanks!
