1 oh or less is reasonable for the heating element, it will get higher
as it gets hot. like you, I would think the thermocouple would be 0, or
infinity, unless it is a thermister type deal. thermostat makes me
wonder though. Is it an electronic type. normally a thermostat is
either open or closed. the readings you gave would be for a control
that turned the amount of heat up and down, but not for a thermostat
that could turn it on and off. Is there a control box all of this wires
to that has a circuit board in it?
