Do you know how much electricity it consumes?

Excellent information.  I'm assuming you've measured the temperature changes
or power usage to determine the defrost time.  I seem to recall it was more
variable in my unit than I expected.  You've confirmed, however, what I am
looking for is a way to detect a "warm up" that's not followed by a cold
enough "cool down" within a specific time frame.  Why did I think you were
using ADI and/or HAI gear?

Great!  Exceptionally useful.  Thanks. On a practical note, how did you run
the wires to the probe and where did you locate it in the unit?
