It's on a bimetal switch of a Black & Decker toaster oven TRO 855 TY8, hidden under an insulating sleeve:

It looks like a bog standard resistor to me

It's a resistor, looks like 10k. Can you tell how it's wired? My first thought was a resistor for a neon indicator but 10k is too low for that IIRC.

The resistor measures 30kΩ, and it is wired to a small light bulb:

Resistor. The “light bulb” is a neon indicator.

Oh, yeah that's a small neon lamp, they need a current limiting resistor just like LEDs.
