I think it must be an improvement in later models.  The ignitor in my
fridge seems to be a totally mechanical "trip hammer" type, where pressing
the knob in causes an impact on a piezo crystal to generate the high
voltage.  To get a repeating effect, you'd need to use some kind of
electronic circuit to generate the high voltage instead.
