This apparent switching diode lays across the fan stream with the heating elements below it. It seemed like the most likely culprit to be replaced.
( L A A A A A AST thing to fault . . . )
Well . . . .still not enough usable info coming forward . . . being specifically relevant to your unit.
Hamilton Beach provides no info their HOME site as being forthcoming . . . ¿ assuming ? . . . that this is just expected to be a $60 toss away unit . . . considering any developed operational problems.
Can I assume that Hamilton Beach consumer model # 32100 is being the unit involved ?
A . . .la . . .
If I
DO go to their commercial product area and research their commercial dehydrator , there I can at least get into their minds and see exactly how their engineering heads are being screwed on . . . .CW ? . . . CCW ? . . . Coarse . . . Fine . . . Metric . . . SAE ?

Now, on that unit, you can see that an AC power line fuse is being involved in its power input flow at bottom right corner.
Then there is the air supply fan., the heating element and the control panel.
I might suspicion that the shown thermostat is just being for an UPPER heat limit protctive precaution.
And if temperature control aspect is involved, it will also be using your same silicon diode junction for temperature sensing in the air flow stack and being wire remoted to the control / display electronics portion.
Then there would likely be a thermally coupled one shot thermal fuse *** being associated with the heater element and possibly the fan motor proper.

They look-a-like-a-dis . . . . and are being CRIMP CONNECTED into circuit just as your is diode as shown,
BECAUSE soldering heat applied to the one lead that is set in ceramic frit, might damage / ruin / melt / blow the internals of the unit on its initial install.
PLUS . . . . you just might find this unit being HIDDEN, in the respect of being nestled INSIDE of a woven, electrically insulative fiberglass sleeve .
So finally now, give some feedback, as to whether the now thermally and air flow DEAD unit is being totally devoid of any digital display or associative indicator lamps ?
Since . . . with that digital display, some power supply electronics is involved with it, whereas the separate and isolated heater and fan aspects may now be the non powered up units.
What say ye ?

I don't have A.D.D., it's just that . . . . . oh LOOK ! a squirrel ! I wonder where it lives . . . . will it run away if I approach it ? . . . .
