Display shows E13; unit may not recognize door position or may not run with door closed.

Safety: Disconnect power before removing door trim or switch assemblies.

Steps:

• Locate the door switch or sensor, typically mounted in the cabinet frame near the top or side of the opening.
• Inspect the switch for physical damage and ensure the door fully depresses the switch plunger when closed, or that the door magnet aligns with the reed sensor.
• Use a multimeter to test the switch for continuity while pressing and releasing it. Replace the switch if it does not change state properly.
• Check the wiring harness from the switch to the control board for pinched or broken wires.
• Install a new Marvel door switch or sensor if needed, ensuring proper alignment with the door.
• Restore power and confirm that the interior light and ice maker respond correctly to door open/close and that E13 clears.
