Like any fixture, stacking doors might face occasional issues. Here’s how to address some common ones:

• Sticking Doors: If the door doesn’t slide smoothly, check the track for debris or dirt. Cleaning and lubricating often solves this issue.
• Misalignment: If panels don’t stack neatly or there’s a gap, it might be a sign of misalignment. While minor adjustments can be done at home, significant misalignments might require professional intervention.
• Locking Issues: If the door doesn’t lock properly, inspect the lock mechanism for any obstructions or damage. In some cases, replacing the lock might be necessary.
• Drafts: Feeling a draft even when the door is closed? Inspect the seals and weather stripping. They might need replacement.
