Guardian Minor Misadjustment of Travel Limits

Guardian opener stops just short of fully open or fully closed position, leaving a gap.

Possible Causes

Travel limits set conservatively, Door travel changed due to hardware wear, Rail length slightly mismatched to door height

Safety first: Keep clear of the door while adjusting limits.

Adjust open limit: Increase the up travel slightly so the door opens fully without hitting the stops.
Adjust close limit: Increase the down travel slightly so the bottom seal just contacts the floor without excessive force.
Test several cycles: Run the door open and closed multiple times to confirm consistent stopping points.
