If the arcing is caused by a loose connection (intermittent open,) then
breaking the circuit anywhere will stop the flow of electricity and
thereby stop the arcing. But if the hot wire is vibrating and touching
ground (intermittent short,) the lack of a bulb isn't going to stop the
arcing.

A fuse should of many times over. The OP says it has been doing this
for a while, therefore it must be an intermittent open.

I know you meant to type "should have."

I didn't know that refrigerator light bulbs were fused.
