Display shows E17 and the refrigerator may beep continuously or show a door-ajar warning even when doors are closed.

Safety first: Unplug the refrigerator before accessing internal sensors.

Check door closure:

• Verify that all doors close fully and evenly. Look for items or shelves preventing full closure.
• Inspect door gaskets for tears, warping, or debris that might hold the door open.

• Locate door magnet and sensor: On some Insignia models, a magnet in the door aligns with a reed switch in the cabinet frame.
• Check alignment: Ensure the magnet lines up with the sensor area when the door is closed. Adjust door hinges slightly if needed.
• Test reed switch: With the unit unplugged, access the sensor in the cabinet and test continuity while placing a magnet near it. Replace the reed switch if it does not change state.
• Replace faulty components: Install a new Insignia-compatible reed switch or door gasket as required.
• Restore power and test: Plug the unit back in and confirm that the E17/door-ajar warning clears when doors are closed.

Note: Persistent false door-ajar warnings after sensor replacement may indicate a control board issue.
