Maintain the synchronized movement and airflow direction of your indoor unit with the Samsung Air Conditioner Link Blade-B DB66-01730A. This critical mechanical linkage connects the vertical or horizontal louver blades to the step motor, allowing them to swing in unison. It ensures that the air is distributed evenly across the room according to your remote settings. If your louvers are hanging limp, moving unevenly, or making a clicking sound without changing position, this plastic link arm is likely cracked or detached.

The DB66-01730A is manufactured from high-durability, friction-resistant plastic designed to handle the repetitive motion of the swing function. Its precision-molded pivot points ensure a snap-fit connection that remains secure even under the constant vibration of the fan motor.

Installation / Replacement Instructions

1. Safety First: Turn off the air conditioner and disconnect the power supply at the main circuit breaker.
2. Open the Front Housing: Depending on your model, you may need to remove the front panel or the bottom louver assembly to gain full access to the internal linkage mechanism.
3. Locate the Linkage: The DB66-01730A is found on the side of the louver assembly, connecting the main swing blade to the motor or to secondary blades.
4. Remove the Broken Link: Carefully unclip the old linkage from the louver pins and the motor crank. Be gentle with the plastic pins on the louver blades, as they can be brittle.
5. Install the New Blade Link: Align the holes of the new DB66-01730A with the pivot pins. Press firmly until the link snaps into place. Ensure the "B" orientation matches the original configuration.
6. Manual Check: Gently move the louvers by hand to ensure the new link allows for a full range of motion without binding or popping off.
7. Reassemble and Test: Reinstall any housing panels you removed and restore power. Use the remote to engage the "Swing" function and verify that the blades move smoothly and in perfect synchronization.

Compatible with select Samsung split-system indoor units, this OEM-quality link blade restores the precise airflow control and quiet movement originally designed for your system.
