I think the way it works is like unto the following...

Pouring batter on the grill causes its temperature to drop, in turn causing
the thermostat to turn on the heating coils -- and the light. When the grill
returns to full temperature, the light goes off.

Mix up some batter and try it out, or turn it over and undo the screws
that should be on the bottom to hold the thing together.
