How To Replace a Sliding Glass Door Roller

When you have a sliding glass door in your home, you’ll want to ensure that it stays in working order for as long as possible. Unfortunately, the moving parts on this type of door are often prone to wear and tear. One common issue with sliding glass doors is a broken or missing roller, also known as a guide wheel, that helps the door glide smoothly across its track. Fortunately, replacing a sliding glass door roller is not overly complicated and can usually be completed in about an hour. There are many different types of rolling mechanisms used on sliding glass doors. Some may require more work than others to replace the broken or missing guide wheels. The instructions outlined here are for double-hung windows that operate through a top and bottom track. If your window operates from the side instead of top-to-bottom, you may need to consult with professionals before beginning this project.

Know the Signs of a Broken Sliding Glass Door Roller

A broken door roller can make your door stick, not glide smoothly, or even cause the door to jam in place. If your sliding glass door is having issues staying open or closed, often both of these problems can be traced back to the door track. A misalignment in the track can often create friction where the wheel touches the track, which can cause the wheel to break. You may also notice that your door track is dirty more than it should be. The wheel and track collect dirt, dust, and grime over time. When a wheel breaks, it can cause extra wear and tear on the track, making it more difficult to clean.

How to Tell If a Sliding Glass Door Roller is Broken

Before you start digging into the problem, it’s best to first determine whether or not the wheel is broken. Simply lift the door gently and see if it stays in place or slides up and down freely. If the door is stuck or doesn’t glide properly, one or more of the wheels may be broken. If the door slides up and down normally, the problem is more likely to be the track itself. If the wheel is broken, you can also see that it’s missing. The wheel is typically hidden behind the door, so it’s hard to see. However, if you can’t lift the door, the wheel is broken and needs to be replaced.

How to Find the Right Replacement Part

Unfortunately, there is no single source you can use to find replacement parts for every brand and model of sliding glass door. At the very least, you’ll need to know the brand and model of the door. From there, you can find the parts online through companies like Amazon, GoDaddy, and eBay. However, you shouldn’t settle for the first set of replacement parts you find online. Instead, it’s best to know what you’re looking for so you can ensure you’re getting the right parts. Many brands have more than one type of door roller. When in doubt, you can always call the manufacturer or visit their website for additional information.

Steps to Replace a Sliding Glass Door Roller

The first step in replacing a sliding glass door roller is to shut off the power to the door. Next, lift the door up and remove the screws that hold the track in place. You should be able to remove the track by lifting the bottom of the track off the roller. Once the track is removed, you can remove the broken wheel by removing the screws that hold it in place. Once you have the old wheel removed, you can install the new track and wheel. Finally, you can reattach the track to the door, turn the power back on, and test the door to make sure it operates correctly.


Replacing a sliding glass door roller is a relatively easy project that can save you money in the long run. A sliding glass door with a broken roller can be very difficult to open and close manually. Replacing a broken roller is quick, inexpensive, and can save you the cost of hiring a professional to fix the problem. Once you’ve replaced the roller, you should keep an eye on the track to make sure it stays in good condition. It’s helpful to clean the track regularly so it stays free of dirt, grime, and extra wear. If you notice the track is wearing down quicker than it should, you may want to look into replacing it.
