Failed attempts
Boards, dispenser and ice maker did not help
The unchanged behavior forced the diagnosis away from components already replaced.

The Flap Reacted to a Door That Did Not Contain the Dispenser
Multiple expensive parts changed nothing. The decisive clue came from the embedded magnetic door switch: its state changed the light, fan and flap together.
What the source establishes
- Closing the left lower door caused the dispenser flap to open and ice to build in the dispenser.
- Two control-board attempts, a dispenser and an ice maker did not change the symptom.
- Wiring continuity checks found no open circuit or stored error.
- A controlled switch-state test made the light, fan and flap respond correctly when the embedded magnetic door-switch circuit was simulated.
- Returning to the door magnet reproduced the problem; replacing the left door resolved it.
A similar symptom can have a different cause on another appliance or model.
How the evidence narrowed the diagnosis
State test
The magnetic door-switch path changed all three functions
Light, fan and flap behavior became correct when the switch state was simulated.
Reproduction
The original magnet brought the fault back
That repeatable reversal localized the failure to the switch embedded in the door.
What the evidence supports
The embedded magnetic door switch sent the wrong door state. Because it was built into the door and not available separately, the confirmed repair required the left lower door assembly rather than another dispenser or control.
Replacing the left door resolved the dispenser behavior
The technician explicitly reported that the problem was solved after the door containing the faulty embedded switch was replaced.
What should be verified next
For the same sequence, record exactly which door movement triggers the flap and whether the interior light and fan change at the same moment. A technician can compare those states before ordering dispenser parts.

Electrical safety: do not cut, jumper or bypass a refrigerator door-switch circuit. The diagnostic state test described here was performed by a technician and the protective behavior must be restored.
