How To Repair Vertical Blinds Carrier Stems and Gears

There is a possibility that you will require a new carrier stem and gear if one of the slats on your vertical blinds has ceased turning in tandem with the others. As you open and close the blinds, the gear turns the slat, which is held in place by the carrier stem, which is also responsible for holding the slat in place. Although this is a simple repair that you may perform on your own, the procedure will change depending on the carrier that you are changing.

Understanding and Replacing Vertical Blind Carriers:

With the exception of one, the stem carriers that are attached to your vertical blinds are all identical. This one-of-a-kind carrier, also known as the lead or master carrier, is the final one that is attached to the headrail of your blind. When you pull the cord to slide your blinds across the window, this is the carrier that is the farthest away from the cord. The fact that this carrier is the one that leads the others down the track is where it gets its name. This carrier is responsible for sliding your vertical blinds up and closed. The additional carriers that are attached to your headrail are also examples of standard carriers.

It is important to keep in mind that although the fundamentals of changing carrier stems and gears are always the same, the specifics may vary significantly from one blind brand to another. Work with caution and take your time, paying close attention to the plastic clips and tabs that are securing your gears and carriers in place. Before you begin working on them, it is important to take a moment to examine them so that you can easily understand how they function. This will ensure that you do not damage them by tugging or pushing in the wrong direction. 

How to Replace a Standard Carrier Stem and Gear

To take out the carrier stem, pull it in the direction of the open portion of the letter “C.” In the event that you require assistance, you can make use of a small screwdriver. It is possible that your blinds will utilize a clip that is slightly different to secure the stem carrier in place; however, the overall configuration should be comparable.
  4. Utilizing a pair of needle-nose pliers, pull the carrier stem gear in a straight downward direction and disengage it from the carrier. 
  5. Proceed to insert the replacement stem gear for the carrier into the carrier. Utilizing either your fingers or your pliers, you should push the gear into position so that the gears are pointing upward. It should not be difficult to snap the gear into position.
  6. Once the new carrier stem has been installed, it should be inserted into the “C”-shaped clip. Ensure that it is oriented in the same direction as the other carrying stems of the vehicle. 
  7. Hang the blind slat back up and conduct a test on your repair.

How to Change a Lead Carrier Stem and Gear

  1. The lead carrier stem and gear changes become somewhat more difficult. To disassemble the headrail for this repair, you must first remove the window’s blinds. The repair is not difficult in and of itself, but you will need to take care not to damage or twist the links and cords that pass through the headrail while you work.
  2. To open the blind, take out the slats and pull the string. As a result, all of the carrier stems will group together.
  3. Take off the window’s headrail.
  4. Remove the cover from the headrail’s idle end. You have the option to twist it off or use clips to secure it. Proceed with caution to avoid shattering any plastic components.
  5. To remove the carrier rail from the headrail, push on its end. This might necessitate taking out a few screws. All that has to be done is slide the rail out far enough to reveal the lead carrier.
  6. Pop or twist the lead carrier stem out of its clip after the lead carrier is no longer attached to the headrail. The lead carrier on some blinds will twist out, while on others, they might require a shove to the left or right. Every blind has a unique set of details.
  7. Take off the gear beneath the carrier stem that is now visible.
  8. After installing the new gear, align it with the other carrier stem gears in the same orientation. If holding on to the gear is difficult, needle-nose pliers may be of assistance. Place the newly installed lead carrier stem over the gear.
  9. Take care not to pinch or twist the cords that operate the blinds as you slide the carrier rail back into the headrail. If you had to unscrew the carrier rail in order to remove it, screw it back into position.

  11. Reinstall the blind slats and hang the headrail back in the window.
