Freezer shows F7 and interior light or fan may not work correctly; display may flicker.

Safety: Disconnect power before removing any switch or trim parts.

Steps:

• 1. Locate door switch/sensor: On many IKEA upright freezers, the door switch is a push-button in the frame or a hidden magnetic reed sensor behind the liner near the top.
• 2. Test mechanical switch: If there is a visible push-button, gently pry it out, disconnect the wires, and test for continuity while pressing and releasing the button. Replace if it does not change state.
• 3. Magnetic sensor: If no visible switch, the unit may use a magnetic sensor. Check the door gasket area for a magnet strip and inspect the wiring behind the top trim. Testing often requires access to the control board and a service manual.
• 4. Inspect wiring: Look for pinched or broken wires where they pass into the cabinet.
• 5. Replace faulty switch/sensor: Install the correct OEM part, ensuring it is seated firmly and the gasket or trim seals properly.
• 6. If F7 persists: The control board input circuit may be damaged and require replacement.

Tip: A faulty door switch can also cause the fan to stop and the light to stay on, warming the freezer.
