Indoor unit shows E7; louvre may not move or may be stuck in one position.

Safety: Turn off power before working near moving parts.

• Check for obstruction: Open the front panel and inspect the horizontal and vertical louvres. Remove any foreign objects (toys, plastic, dust build-up) that may block movement.
• Manually move louvre: Gently move the louvre by hand with power off. It should move smoothly. If it is jammed, inspect the side pivots and link arms for damage.
• Access swing motor: Remove the front cover to expose the swing motor (usually on one side of the louvre assembly). Check that its connector is firmly plugged into the indoor PCB.
• Inspect gears: Look for stripped plastic gears or broken linkages between the motor and louvre.
• Replace faulty parts: If the motor is not turning when swing is commanded (with power restored) and no obstruction is present, replace the AEG swing motor assembly or louvre kit as per model.
• If E7 persists after motor replacement: The indoor PCB output may be faulty and should be checked by a technician.
