What is Inside a Microwave Oven Probe?

They arent all done the same way, some have a thermocouple,
some have a thermistor, some have a resistor that changes
its resistance with temperature.

Mine seems to have gotten intermittent, and I'm curios to know how they're
made.

Likely just a wiring failure, cracked wire now.
