Warning: That old Kenmore dryer might have a hidden fuse you never knew about

I was working on a 90s Kenmore dryer last week, the kind with the big dial timer. It had no heat, and I checked the usual stuff, the heating element, the thermostat, the thermal fuse. All good. I was about to call it a bad timer when I found a forum post from a guy in Milwaukee talking about a 'safety thermostat' tucked behind the drum housing, not on the blower housing like the newer ones. Sure enough, I pulled the drum, and there it was, a little white disc I'd never seen before on that model. It tested open. Replaced it for about $12, and the heat came right back. I've been doing this for eight years and had never run into that specific part placement on those older units. It's wild what you can still learn from other techs online. Has anyone else found a weird hidden part like that on an appliance you thought you knew inside and out?

That "knowledge disappears" stuff is overblown, most of those old tips are just guesses. Even @henry_campbell15's buddy probably just misread the wiring diagram.

My buddy found a hidden fuse in his fridge once.

It makes you wonder how many older models have those undocumented service bulletins. The factory manuals sometimes miss updates, and the only record is in some technician's notes from twenty years ago. That knowledge disappears when people retire unless it gets shared online. We're basically doing archaeology on machines that are still running.
