Before You Begin

The obstruction blink code occurs when the shade senses issues with the movement of the fabric panel. This can be caused by the following:

  • Interference with the fabric or hembar.
  • Manual operation of the shade.
  • Limits are set too high


Inspect your roller shade for obstructions to the fabric and/or bottom bar. If the shade is rubbing or catching on anything, adjust the shade to prevent it from striking the object.


After confirming there is nothing obstructing the shade, follow the steps below to continue troubleshooting:

Section 1: Factory Default the Shade to Clear the Obstruction Blink Code

If your shade strikes another object or is manually manipulated, it must be returned to factory default to clear the error code.

Watch the video or follow the step-by-step instructions below to factory default your shade:



To factory default your shade, follow the steps below:

  1. Locate the shade’s Indicator Light (IL) button.
  2. Tap the shade button quickly 3 times and hold the button after the third tap until the IL blinks green rapidly.
  3. Immediately release and tap the shade button quickly 3 more times. Do not hold. The shade button will blink green rapidly then blink red/green 3 times and turn off. This indicates a successful factory default.


Important: Factory defaulting will remove the shade from any previously paired remotes or systems. The shade must be added back to the prior system or paired with the previous remote. Factory defaulting does not affect the shade’s upper and lower limit settings.

Section 2: Obstruction Blink Code Occurs Only After Opening Shade


When the Obstruction Blink Code occurs after opening the shade, the Open Limit is set too high. Click here for instructions on How to Reset Lutron Roller Shade Settings Limits.

Reset the Open Shade Limit at least ¼” (0.25in.) / 0.6cm. lower than the point where the button blinks.
