Wine cooler shows E5 and interior lights or door alarm behave abnormally; door status may be misreported.

Safety: Disconnect power before removing door trims or switch housings.

Steps to address E5:

• Locate door sensor: On many Fisher & Paykel wine coolers, the door switch is a magnetic reed sensor in the cabinet frame and a magnet in the door.
• Check alignment: Verify that the door closes fully and that the magnet aligns with the sensor area. Adjust door hinges if the door is sagging.
• Inspect sensor and wiring: Remove the inner trim or small cover over the sensor and check for loose connections or damaged wires.
• Test sensor: With power off, disconnect the sensor and test continuity while placing a magnet near it. The switch should open and close reliably. Replace the sensor if it fails this test.
• Verify at PCB: Ensure the door switch harness is firmly connected to the main control board.
• Replace components as needed: Install a new door switch or magnet if defective. If E5 persists, the main PCB input circuit may be faulty.
