Display shows E7 and the refrigerator may not cool or may show incorrect temperatures.

Safety first: Disconnect power before removing door switch or trim pieces.

Quick checks:

• Verify that the door closes fully and that no shelves or containers are preventing a tight seal.
• Check for a small magnet embedded in the door frame (for reed switch systems). Ensure it is present and not loose.

Door switch test:

• Locate the door switch (often at the top or side of the cabinet opening).
• Gently pry it out with a plastic tool, being careful not to damage the liner.
• With the fridge unplugged, disconnect the switch and test continuity with a multimeter while pressing and releasing the plunger. The reading should change between open and closed.
• If the switch does not change state, replace it.
• Inspect wiring for breaks or loose connectors and repair as needed.

After replacement: Refit the switch, restore power, and confirm that interior lights and alarms behave correctly and that E7 is cleared.
