I'm learning about electronic components. I believe this is the part which has broken and made this heating pad unsafe to use. Well, unusable, not just unsafe lol.

No, there's no fuse here. From top to bottom, there is an electrolytic capacitor, zener diode, and a 4MHz resonator.

Ding ding ding

For op, ZD means zener diode.
