Keystone air conditioner louvers do not swing or adjust direction automatically.

Steps:

• Check for obstruction: Ensure nothing is blocking the louvers from moving. Remove any foreign objects.
• Manual movement: Gently move the louvers by hand. If they are stiff or jammed, inspect the pivot points and linkage for damage.
• Inspect motor and wiring: Remove the front panel to access the louver motor. Check that the harness is connected and not damaged.
• Replace motor or linkage: If the motor receives power but does not move, or if the linkage is broken, replace the louver motor assembly or linkage parts with Keystone-compatible components.
