Aroma rice cooker dead, is it usually just the fuse?

how did you even find that? did you inspect it under a light?

Used a magnifying glass. Under close inspection the trace was cracked in half where it flexes when you screw the control board back into the cooker. Classic aroma move of using cheap thin pcb material.
 
You guys are missing the obvious one. The magnetic switch that detects when the pot is in place. If that fails then it thinks there is no pot in place and refuses to heat up the pan.

different failure mode. OP's problem is that there are no lights at all when the cooker is plugged in.
