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.

If you're looking for a fault and can't see it, it's sometimes possible to sniff it out. Components can be burned out, but the damage is barely visible, if at all. It could be a tiny crack in the packaging. It will often smell like burnt plastic for a long time. Locate the rough area and concentrate on these parts.
