#3011 Heating Pad Failure. Fault Light Came On and nothing would work. The pad was about 8 years old and folded up and stored away many times. Perhaps just old and worn out.
I had the exact same pad fail the same way. I spent a good while trying to figure out the problem, and never did. But at least I did have the correct weird screwdriver 😝
This doesn't even qualify as a teardown; I guess it could be called a "Rip-It"! Try this on a fullsize heating blanket and you'd have to call it a "sheet-y" disassembly! 😉😁
