Noisy Sewing Machine? Here’s Why It Happens and How to Make It Smooth Again

A sewing machine should run smoothly — a steady hum, a clean stitch, and a comfortable flow. But if your machine suddenly becomes noisy, rattles, squeaks, or vibrates more than usual, it’s a clear sign that something needs attention.

Here are the most common reasons sewing machines become noisy, and exactly how you can make the machine smooth and quiet again.
