Rheem ductless indoor unit louvers do not move or are stuck in one position.

Safety first: Turn off power to the indoor unit before manually moving louvers.

• Check for obstructions: Inspect the louvers for objects or dirt buildup preventing movement. Remove any obstructions.
• Manual movement: Gently move the louvers by hand. If they are very stiff or jammed, the linkage may be broken.
• Inspect motor and linkage: Remove the front cover to access the louver motor and linkage. Look for broken plastic arms or stripped gears.
• Replace motor/linkage: Replace the louver motor assembly or linkage kit with the correct Rheem part if defective.

Warning: Do not force louvers; this can strip gears and worsen the problem.
