What causes a zipper to break or get stuck?

There are several reasons why a zipper can break or get stuck:

  • Worn-out teeth or slider
  • Dirt or debris on the teeth
  • Misaligned teeth
  • Weak thread

  1. Identify the problem: Check if the teeth are misaligned, the slider is worn-out, or the thread is loose.
  2. Try to fix the problem: If the teeth are misaligned, use pliers to gently move them back into place. If the slider is worn-out, replace it with a new one. If the thread is loose, sew it back using a needle and thread.
