Repair Guide for Vertical Blind Tracks
Vertical blinds run on tracks, but sometimes the stem that holds the louvers or the worm gear that runs from the tilt rod to the stem need to be repaired. Follow these instructions:
NOTE: If you find that the carrier body itself is cracked or broken anywhere, the new stem and worm gear won't work. If this is a new track and it was damaged in shipping, we will replace it free of charge. Similarly, if the track is from a past order still under warranty we will replace the track free of charge.
1. Using the metal beaded chain, rotate the louvers straight open. NOTE: They must be exactly straight open, perpendicular to the window.
2. Here is a view of the stems holding the louver (or "vane"), the carriers, and the carrier body in your vertical blinds track.
3. Using a pair of needle nose pliers, you can remove the stem. Twist them against the carrier body and the base of the stem. It should not take much effort to pop out the stem.
4. Next step is to extract the worm gear from the carrier body. The track needs to be straight open to remove this piece.
5. Here is a view of the worm gear and stem removed from the still-installed carrier body.
6. Replace the old worm gear with a new one as shown in the picture above. Remember, that this will work only if the track is fully open, so that the louvers are perpendicular to the window. You can hold it at the very tip, positioning the teeth facing upwards and slip the new worm gear into place.
7. Here you see the new worm gear in place in the carrier body.
8. Now the stem can be replaced by pushing it into the carrier body. Place one finger on each side of the carrier body to hold it fast. Now push in the step, applying a solid amount of pressure and listen for the "click". If you don't hear the click, you have not yet used enough pressure. That's it. Once you hear the click, you can re-hang the vane or louver. You're done.
