It is this device here:
http://www.staples.com/krieger-ult450-450-watt-step-up-down-transformer/product_24314473
I think it is a step-up transformer. What would be the difference?

In some designs, the line frequency is tapped as a timing source.
However, in this case, as you pointed out, it seems designed to run on
50 or 60.... so not the problem. Is your supply an inverter or just a
step up transformer?

Terry, I am not sure how the microcontroller would even feel the
60Hz,
but I ordered a special security bit that will let me open the
housing
and inspect the electronics.
Charles, how would I check that? I don't think that it resets,
though:
if you look at the beginning of the video I posted you see that
there is
a brief display of the target temperature (400C) as well as the unit
system 'C' at the beginning. Now if the microcontroller would reset,
then this startup animation should show again I think. So maybe it is
something different?
Do you think I could hook up something in parallel that would
smoothen
the signal?
