Hope the diagram is correct. Next to it is a circuit board viewed from the same direction.

Thanks !

I will try to redraw it, separating "power" from "logic" to make it clear how it works

The unknown resistor looks like a PTC. You can measure its resistance at room temperature to get a clue of its value

Its value is about 100 ohm at room temperature. After being in the freezer, the value is about 130 ohm. That would mean the NTC- resistor?

It would but it sorta makes no sense why would an NTC be used there. What happens if you heat it ? (heat it slowly and uniformly with hot air or the like - non uniform heating from one side might make it ast as a thermoelectric pair and screw your measurement)

I don't know why freezing seemed like that. By heating the value rose to several kilo-ohms. Probably it is a PTC.
