Sometimes our stacker doors will stop working properly and will simply refuse to move or will feel like they’re falling out the track when you push them open. One of the main causes of these problems is damaged rollers due to age or debris being trapped in the track. Fortunately, there is a way that you can repair the rollers, ensuring the your door opens and closes smoothly once more.

Step 1: For a door that is stuck, check the track for any debris that may have accumulated and clean it out. You could also try lubricating the rollers using a penetrating oil to get them moving again.

Step 2: For a door that wobbles or sticks, you might need to adjust the rollers. Locate the adjustment holes (near the top and bottom rollers). Insert a screwdriver and turn it counterclockwise for loose rollers and clockwise for tight ones.

Step 3: Remove the stacker door from the track and inspect the rollers for any sort of damage. If they appear to be cracked, worn out or otherwise broken, you will need to undo the adjustment screws and replace them with some brand new rollers.

Step 4: Inspect the track for any signs of wear or damage. If it has been broken in some way, you will need to remove the screws and fit the doorway with a replacement track.

If you have reached the end of step 4 and still haven’t been able to rectify the problem that your stacker door is experiencing, you will need to contact a professionals to come out and diagnose the problem for you. It may just be that you missed an issue with the door when working through each of the above steps, or it may be a more serious issue.
