How to Fix Cordless Blinds That Won’t Go Up

4.7/5 - (23 votes)

Both of your blinds are stuck in place, either up or down. The problem might be with the controls on either end of the headrail. If one is broken, but not both, you can fix one side independent of the other.

How To Fix Cordless Blinds That Won't Go Up

Simply replace that control first to see if that corrects the issue before addressing this with a full replacement of both controls.

Solution 1: Open Controls

If your controls open easily by pushing them directly upwards towards where they’re mounted on the wall, skip to step 2 for fixing your blinds with the bent cords. If both controls are stuck in place, check to see if they’re still connected to the headrail by testing that one side of the cord is secure once you remove it from the control.

First, detach one end of the blind cords from each respective control.

You can disconnect them safely by pressing down on a small pin on top of each headrail control’s faceplate with either an earring or fingernail for leverage before gently pulling up on the chord coming out of its side. Set this piece aside temporarily. Use your needle nose pliers to pull up on these pieces located under where your old cord connects at the bottom inside of each plastic headrail casing (or where there should be one). The second metal piece will pop up and you can remove it.

You may need to curl the pliers’ noses backwards so they reach behind the bend of the headrail casing to get a solid grip on this locking tab.

Once both pieces are removed, slide your old cord out completely from under where each control is mounted.

Make sure you never pull downwards on either cord when removing them—you will break them and create more work for yourself later.

Next, shut off all power to your blinds before inserting your new cords into their respective openings and gently pulling one side through at a time until they’re secure in place inside each metal piece attached to the backside of its corresponding headrail control. The easiest way to avoid getting your cords crossed is to have two similar blinds next to each other—one with its right cord plugged in at the top and left cord plugged in at the bottom, and vice versa. Then work on your opposite blind first before testing them both out together.

They should both raise and lower smoothly now. If they still don’t, move on to step 3 below for more assistance or alternate methods of removing your faulty headrail controls without breaking their attached locking tabs (but only attempt this if you’re familiar with how these types of blinds function). Then repeat steps 1-2 above for the second control, making sure that once disconnected it can be opened freely by pushing it directly upwards towards where it’s mounted onto the wall. These pieces are spring-loaded and should snap back in when you hit the sweet spot.

If this doesn’t work, skip to step 2 below for instructions on how to replace these controls with new ones or call a professional for assistance because there may be an additional issue with the headrail itself that cannot be fixed without replacing it.

Solution 2: Bent Cord

Before seeking any assistance, try straightening your bent cord yourself—you might just have one side in the down position while the other is stuck up in place. You can usually fix both sides independently using similar techniques to open your controls if that’s not the case. Here are some steps you can take at home before calling for help:

Remove all power to your blinds before attempting any of these solutions.

Unplug both blind controls from their sockets on the wall and set them aside as you were doing earlier. Next, take an earring or another thin piece of metal to help pry your bent cord out straight—they’re probably stuck at the bottom due to a locking tab that was bent during delivery or installation (see below for more about those).

Once you’ve straightened out the cord and removed it from under its corresponding headrail control, attach one end back into place and gently pull until this section slides underneath the metal locking tabs located towards the top inside each side’s plastic casing where it should snap securely back in. If not, see the next section for detailed diagrams and instructions.You can do this on both sides or just one depending on how they’re configured.

If the curvature of your bent cord isn’t too severe, you can also try to use these same techniques above to straighten it out by pulling your new cord upwards gradually with some force—it might just work.

Solution 3: Headrail Connector

The plastic connector piece that attaches the bottom of each headrail apparently has a way of becoming pressed down and stuck if you press on it too hard while opening your blinds. If this occurs, usually someone will lean all their weight onto the control arm to lower the blinds manually—only now they are unable to raise them because there’s nothing left under this locking tab for it to snap into place. A temporary way to fix this is to push the headrail connector piece upwards until it flips back underneath itself vertically where it should snap in without being pressed down anymore. This will allow you to raise your blinds again, but will also have to repeat this process each time you open or close them like before (if not worse).

If your headrail connector feels jammed and fastened after pressing on it slightly with your hands, there’s nothing wrong with calling an expert for assistance because they can likely fix this problem quickly while they’re at your home working on other things—plus their services are usually inexpensive compared to what you’d end up paying otherwise. You can read more about these types of headrails here.

The good news is that usually headrails only get damaged or worn out after years of being used, so yours will probably be fine for the time being. However, if you have a brand new set and your cordless blinds already aren’t working properly, it’s possible someone mistakenly switched the headrail connector piece from one side to another while installing them—or something else was done incorrectly during installation or setup. In this case, you should contact the retail store where you purchased your blinds for assistance—they’ll likely send an independent installer back to your home to make sure everything’s connected correctly before charging you any additional fees (on top of what they already sold you).

Solution 4: Locking Tab

If your locking tab is bent downward, you can use pliers to carefully bend it back up, but usually, this bend will curve back down after a few uses. Instead, use the same technique as solution 2 above to cut off your cord’s head, pull out the tab underneath another tab that’s flipped upwards vertically using two fingers to hold both pieces away from each other so they can’t be damaged—and then reattach everything back together once it has been freed.

Some locking tabs are riveted in place with visible Phillips-head screw heads or other visible metal fasteners inside these plastic casings — so instead of cutting through your blinds’ chord completely, just try removing these screws and taking note of where their corresponding parts go before replacing them back into their original positions.

Solution 5: Cordless Blinds

Generally, corded blinds are more user-friendly and convenient to operate because of their built-in pull cords—especially for high windows with a lot of reach involved. Unfortunately, cordless blinds were often marketed as a great “newer” modern feature that actually just added unnecessary complications and hassles to using them compared to the traditional types that most people grew accustomed to over the years. It’s not surprising why this happens with any new technology—people just aren’t used to such products until they’re around for long enough to be deemed reliable and dependable throughout several generations or decades of use (irrespective of how inconvenient they may be at first).

With this said, cordless blinds are still the most popular type of window treatment available today—even though they’ve been around for over 30 years. If you want to avoid the hassle of using them (without having to completely replace your existing windows), simply cut off their chord instead like mentioned above or just pull up on your lower blinds’ control arm several times before locking it into place again. This should release tension that causes the lock tab switch to stick downwards and prevent your blinds from automatically raising all the way up each time after it’s pulled back down to raise them.

If you must have cordless blinds, spend a little more money on higher quality brands or models so you can at least get something more durable and dependable that will last for several decades (rather than a few years like most other cheap brands).

You’ll get what you pay for in such cases, so it’s usually better to invest more money upfront on quality rather than having to spend even more later down the road trying to repair or replace them.
