I put the meter across the heating element and turned the refrigerator on AC with the temperature selector to "on" so that the element should be on all the time. No heat! I then found that I had no voltage to the control box in the fridge.
There is an double AC outlet, out of sight in the outer wall above the lower refrigerator vent. I plugged in an extension cord in the unused socket, the circuit tracer into the cord, and had voltage. I then moved the refrigerator cord to that socket and, voila, I had voltage and heat.
I checked the original socket that the refrigerator was plugged into and it seemed to be intermittent. The socket I moved the refrigerator to seems to be solid as a rock. I'll just leave it there since the refrigerator would have to be removed to change the outlet.
Another bullet ducked!
