Indoor unit displays E7, louver may not move correctly

Safety first: Turn off the unit with the remote and isolate power at the breaker before manipulating louvers.

Steps:

• Check for obstruction: Gently move the louvers by hand (do not force). Remove any objects or heavy dust buildup preventing movement.
• Inspect linkage: Open the front panel and observe the plastic arms and gears connecting the motor to the louvers. Re-seat any arms that have popped out; replace broken pieces.
• Test operation: Restore power and command the unit ON. Watch if the louvers attempt to move. Clicking without movement suggests a jammed or stripped gear.
• Replace louver motor: If the motor does not run or is noisy and the louvers are free, replace the louver stepper motor assembly for your model.
