That 'fuseable link kinda thing' is a thermal cut-out. A one shot heat sensing fuse that’s normally closed and sends power to the thermostat.
When tripped by excessive heat (190°F), (i.e. blocked burner or flue tube) it cuts power to the circuit board and shuts down ignition
If removed and still will not fire up then check for 12V power from circuit board to/thru normal t-stat and back to circuit board (brown wire)
