Thomas, suggest you use the ohmmeter at a low range to measure
continuity from the cord to the heater terminal, with the fridge
turned on (but not plugged in, of course) and thermostat
midrange.  You should see approximately zero ohms.  If you don't,
work from the ends toward the middle to find where the connection is
broken.  Likewise on the return path from the other heater terminal
back out the cord.

For the heater itself, the resistance should be less than 140 ohms,
possibly a good deal less (the element will have lower resistance
when it's cold than when at working temperature).

Does that help?
David
