Indoor unit displays E7; louver may not move correctly

Safety: Turn off power before manually moving louvers.

• Check for obstruction: Inspect the swing louvers for foreign objects or misaligned vanes. Gently free any jammed parts.
• Manual movement: With power off, gently move the louver through its full range. It should move smoothly without binding.
• Inspect linkage: Remove the front cover and check the plastic gears and link arms between the motor and louvers. Replace broken parts.
• Replace stepper motor: If the motor does not respond when swing is activated, replace the louver motor assembly.
