No, it removes the bulb, but leave an open socket and the same loose
connection that can still arc to something grounded.
It is also possible that the bulb itself has a loose filament and is causing
It could be something simple as a defective door switch. Unplug the
fridge, then remove the door switch and jump it out, then plug in the
fridge again. If the light stops flickering, you found the problem.
I don't believe you have a working grasp of what a "complete circuit"
entails. Arcing will occur at the point of any loose connection. The greater
the load on the circuit, the more arcing that will occur. Any method that
you employ to open that circuit will prevent arcing from occurring. You can
open the hot leg. You can open the neutral. You can remove the "load", in
this case, light bulb. All will open the circuit and prevent arcing at the
point of the loose connection.
