Often, there is a relay that controls the light. When the door has been
open for several minutes and you break the beam, do you hear a click? If
you hear the click, you might be able to trace the wiring between the relay
and the fixture and perhaps find a bad connection or solder joint on a
printed circuit board.
Otherwise the relay, if there is one, could be bad.
