Occasional adjustments are sometimes needed to keep a window operating smoothly. One of those changes that might be necessary is roller adjustments. This article will guide you through how to adjust sliding window rollers for smooth operation of your Milgard window. (Please make sure to read our FAQs disclaimer before reviewing or enacting any FAQ content/recommendations.)
The materials that you need for this procedure include a flathead screwdriver, silicone spray, paper towels, safety glasses, and gloves.
The first step is to remove the sash from the frame. To do this lift up on the sash and tilt the bottom out of the track. If you look at the bottom of your window, you will see two assemblies that have vinyl wheels. You will notice that there are two positions for the wheel in each assembly. Taking your flathead screwdriver, carefully snap the wheel out of its casing. Then raise or lower the wheel until it is at the desired place. Using your screwdriver again, lock the wheel back into the place. Do that for every wheel in each of the assemblies until all the wheels are in the correct position for the best operation of the window.
Once the wheels are in the right place, it is time to clean the rollers. Before you begin, make sure the wheels can move back and forth and there is no debris in the track. Then, take the silicone spray and give each wheel just one spray. Then take the paper towel and wipe each wheel until it is dry. Finally, to reinstall the sash, tilt the top of it and place it back into the top of the track. Carefully reinsert the bottom of the sash onto the bottom of the track and push down. Then, just slide the sash back and forth to make sure it works correctly.
