A serger is a fantastic machine that creates professional, durable seams with impressive speed, but that power can come with considerable noise. While these machines are naturally louder than standard sewing machines, excessive rattling or grinding sounds indicate an issue that requires troubleshooting. Learn how to keep a serger quiet, smooth, and reliable with simple, consistent maintenance. These tips will improve your sewing experience and extend the life of your valuable machine.
Choose the Right Surface
Where you place your serger plays a huge role in how much it vibrates and the noise it produces. A flimsy card table or unstable desk will amplify every movement, creating a racket that can be quite distracting. Select a solid, heavy piece of furniture, like a sturdy sewing cabinet or a heavy-duty table, for a stable foundation that absorbs vibrations.
Additionally, you can place a serger or sewing machine mat beneath your machine for an extra layer of sound-dampening. These mats are made from dense foam or rubber, which reduces vibrations and results in quieter operation.
Clean Your Machine Regularly
Lint and fabric dust are the primary enemies of a smooth-running serger, as they build up quickly inside the machine’s complex mechanics. This debris can clog the feed dogs, interfere with the loopers, and dull the blades over time. To keep your serger quiet, smooth, and reliable, you should get into the habit of brushing out the lint after every major project or after a few hours of use.
A small, stiff brush and a can of compressed air are excellent tools for reaching into tight spaces around the loopers and cutting knives. However, when using compressed air, be careful not to blow the lint deeper into the machine’s housing. Consistent cleaning goes a long way toward preventing noisy problems down the road.
Proper Oiling is Essential
Just like any machine with moving parts, a serger needs regular lubrication to function smoothly and quietly. When metal components grind against each other without lubrication, it creates friction, produces excess noise, and causes premature wear. Your serger’s manual will show the specific oiling points and recommend a lubrication schedule.
Only use high-quality sewing machine oil, as other lubricants can gum up the internal mechanisms and cause damage. Over-oiling can attract lint and create a messy building, so apply just a single drop of oil to each point indicated in your manual. Afterward, run a scrap piece of fabric through the serger to distribute the oil and catch any excess drips before starting your next project.
Check Your Needles Frequently
A dull, bent, or incorrect type of needle is a common cause of serger noise and performance issues. A damaged needle has to punch through the fabric with excessive force, producing a loud thump and potentially damaging the material. It’s a good practice to start every new project with a fresh needle.
You should also use the correct needle type and size for your specific fabric. Using a ballpoint needle for knits and a sharp needle for wovens prevents skipped stitches and reduces strain on the machine’s motor.
Here are some signs that it’s time to change your needle:
- You hear a popping or thumping sound as the needle enters the fabric.
- The machine starts skipping stitches or creating uneven loops.
- Your fabric shows signs of snagging or pulling.
- The thread keeps breaking or shredding for no apparent reason.
- You have been sewing with the same needle for six to eight hours.

Threading Your Serger Correctly
Improper threading is one of the top reasons for a noisy and malfunctioning serger. When threads are not seated correctly in the tension discs or are wrapped around the wrong guides, the machine will struggle and make clattering sounds. Always thread the machine in the order your manual specifies, which is usually upper looper, lower looper, right needle, and then left needle.
Make sure each thread is securely snapped into its tension channel so the machine can properly control the flow of thread. A serger overlock machine uses multiple threads to simultaneously seam and finish an edge, making correct threading critical for a balanced, quiet stitch. On a related note, using high-quality, smooth serger thread also contributes to a quieter operation, as it moves through the guides with less friction.
Tighten All Visible Screws
The high-speed vibrations of a serger can gradually loosen screws on the machine’s exterior. A loose needle plate screw or presser foot screw can cause rattling noises and affect stitch quality. Periodically, take a moment to check and gently tighten any screws you can access.
Pay special attention to the screws holding the needle plate, presser foot, and any exterior covers. Use the screwdriver that came with your machine to get the right fit and avoid stripping the screw heads.
Use the Correct Presser Foot
Using the appropriate presser foot for your chosen stitch and fabric helps the machine operate more efficiently. The standard serger foot works well for most general-purpose overlocking, but specialized feet offer better control for specific tasks. For example, an elasticator foot guides elastic perfectly, and a gathering foot creates even ruffles without extra work.
When the correct foot is attached securely, it holds the fabric firmly against the feed dogs, allowing for smooth and even feeding. This proper fabric control minimizes strain on the motor and reduces the clattering sounds that can occur with poor feeding.
Adjust the Cutting Blades
Dull or improperly aligned cutting blades will make your serger work harder and louder. Instead of cleanly slicing the fabric, dull blades will chew or bunch the material, creating a knocking sound. You can tell your blades are dull if the fabric edge looks ragged or if threads get caught in the cutting mechanism. Most sergers have an upper and a lower blade, and your manual will provide instructions on how to adjust, retract, or replace them.
Here is a quick guide to managing your blades:
- Consult your manual to learn how to retract the upper blade for decorative stitches.
- Clean the blades with a small brush to remove any built-up lint.
- Check the blades for visible nicks or damage that could snag fabric.
- If the edge is no longer clean, consider sharpening or replacing the blades.
- Always unplug the machine before making any blade adjustments.
Schedule Professional Service
Even with diligent home maintenance, your serger benefits from a professional tune-up every one to two years, depending on your usage. A certified technician can perform a deep cleaning and oiling, reaching parts of the machine you cannot access. They will also check the timing, adjust blade positions, and recalibrate tensions to factory standards.
This level of service is the best way to resolve persistent issues and keep your machine in peak condition for years to come. Think of it as a spa day for your serger, giving it the expert care it needs to perform at its best.
A well-maintained serger is a joy to use because it makes beautiful, even seams. Tightening screws, replacing dull blades, and other regular maintenance keep the machine running efficiently. Paying attention to details like threading and tension settings also prevents unnecessary noise and wear. If you are ever in doubt or face a problem you cannot solve, bring your machine to a trusted technician for professional care.
