Threading a Kenmore sewing machine in the correct order

Threading a Kenmore sewing machine follows the same basic path on most models: the thread goes from the spool, down through the tension discs, up through the take-up lever, and finally through the needle. The exact positions of these parts vary slightly between Kenmore models, but the sequence is almost always the same. If you thread out of order, the machine will not catch the bobbin thread, and your stitches will fall apart.

The most common mistake is skipping the take-up lever — the small metal arm that moves up and down on the left side of the needle. If you bypass it, your tension will be wrong and the thread will slip. The second mistake is threading the needle while the presser foot is down. The presser foot must be up to open the tension discs, or the thread will not sit between them properly.

Key Takeaways

  • Raise the presser foot before threading so the tension discs open and accept the thread.
  • Thread must pass through the take-up lever — the small arm that moves vertically — or tension will fail.
  • The needle goes in last, after the thread has passed through all other guides and the take-up lever.
  • If stitches are loose or the thread breaks, rethread the entire machine rather than adjusting tension first.

Step-by-step threading for Kenmore machines

Step 1: Raise the presser foot. Push the lever at the back of the presser foot upward. You will hear or feel a small click. This opens the tension discs so the thread can slide between them. If the presser foot is down, the discs stay closed and the thread will not catch.

Step 2: Place the spool on the spool pin. The spool pin is the vertical rod at the top left of the machine. Push the spool onto the pin so it sits flat. If your thread is thin or the spool is loose, use the small felt washer that came with the machine — it goes on the pin after the spool to hold it steady.

Step 3: Guide the thread down through the first guide. Most Kenmore machines have a small hook or loop at the top of the machine, just below the spool. Pull the thread down and to the right, letting it rest in this guide. This prevents the thread from tangling on the spool.

Step 4: Thread through the tension discs. The tension discs are two metal plates that sit vertically, one behind the other, in the middle of the machine's upper section. Pull the thread down and slide it between these two plates. You should feel slight resistance — that is correct. The thread must sit fully between the plates or tension will not work.

Step 5: Thread the take-up lever. Just below the tension discs, you will see a small metal arm that moves up and down. This is the take-up lever. Thread the needle's thread through the hole or loop at the top of this arm. This step is essential — skipping it is the most common reason stitches fail.

Step 6: Guide the thread down to the needle. Pull the thread down the left side of the needle bar. Most machines have a small guide or hook just above the needle. Let the thread rest there before moving to the needle itself.

Step 7: Insert the thread into the needle. The needle is at the bottom of the needle bar. On most Kenmore machines, the needle faces you, and the thread enters from left to right. Insert the thread into the eye of the needle, making sure it goes all the way through. A small amount of thread should hang below the needle.

How to know if you threaded correctly

The easiest test is to hold the presser foot lever down and gently pull the thread upward. If the thread is threaded correctly, you will feel resistance from the tension discs. If the thread pulls freely with no resistance, it has skipped the tension discs or the take-up lever.

Another test is to sew a few stitches on scrap fabric without inserting the bobbin. If the thread is threaded correctly, you will see a line of thread on the top of the fabric, even though there is no bobbin thread underneath. If nothing appears, the needle is not threaded or the thread is not in the needle eye.

Once you have sewn a few stitches with the bobbin in place, look at the underside of the fabric. The top thread and bobbin thread should interlock in the middle of the fabric layers. If the top thread is loose or loopy, the top thread is not threaded correctly — rethread from the beginning rather than adjusting the tension dial.

Common threading problems and fixes

Thread breaks while sewing. This usually means the thread is not sitting properly between the tension discs, or the needle is bent or inserted backward. Rethread the entire machine, starting with the presser foot up. If the thread still breaks, check the needle — remove it, hold it up to the light, and look for a bent shaft or a burr on the eye. Replace the needle if you see damage.

Stitches are loose on top. The top thread is not under enough tension. First, rethread the machine completely. If the stitches are still loose after rethreading, the tension dial may need adjustment, but rethreading solves this problem about 80 percent of the time. Only adjust the tension dial if rethreading does not fix it.

Stitches are loose on the bottom. This usually means the bobbin is not wound correctly or inserted incorrectly, not a threading problem. Check that the bobbin is wound evenly and inserted so the thread catches in the tension spring of the bobbin case. If the bobbin looks correct, rewind it and try again.

Thread tangles around the spool. The thread is not resting in the first guide below the spool. Make sure the thread goes down and to the right into the small hook or loop at the top of the machine before it goes anywhere else.

Threading different Kenmore models

Kenmore makes machines in several size categories — portable machines, cabinet machines, and computerized models — and the threading path is slightly different on each. However, the basic sequence never changes: spool, first guide, tension discs, take-up lever, needle guide, needle.

On portable and cabinet machines, the tension discs and take-up lever are in the same location, and threading is straightforward. On computerized Kenmore models, the path is the same, but the machine may have additional guides or a more complex upper section. Consult your machine's manual for the exact location of each part if you cannot find the tension discs or take-up lever.

If you have lost your manual, Kenmore publishes threading diagrams on its website for most models. Search for your model number — it is printed on a sticker on the back of the machine — and read the PDF. The diagram will show you exactly where each part is on your specific machine.

When to replace the needle

A bent, dull, or incorrectly inserted needle is the second most common cause of threading and stitching problems. Needles wear out after about eight hours of sewing, and they bend easily if you pull the fabric toward you while sewing or if the presser foot is raised while the needle is in the fabric.

Replace the needle every time you finish a project, or sooner if you notice thread breaking, skipped stitches, or a popping sound as the needle enters the fabric. A new needle costs between one and three dollars and takes 30 seconds to install. It is the cheapest fix for most sewing problems.

Frequently Asked Questions

Can I thread the needle while the presser foot is down?

No. The presser foot must be up to open the tension discs. If you thread with the presser foot down, the thread will not sit between the tension discs, and your stitches will be loose or the thread will break. Always raise the presser foot first.

What if the thread will not go through the needle eye?

The needle may be inserted backward or upside down. Remove the needle, check that the flat side faces the correct direction for your machine, and reinsert it. If the thread still will not go through, the needle is bent or the eye is damaged. Replace it with a new needle.

Do I need to rethread if I change thread color?

You do not have to, but it is a good idea. Old thread can leave lint in the tension discs and guides. If you are changing to a very different thread weight — from thin to thick, for example — rethread so the new thread sits properly in the tension discs.

Why does my thread keep breaking?

The most common cause is incorrect threading. Rethread the entire machine, making sure the thread passes through the tension discs and the take-up lever. If the thread still breaks, check the needle for bends or burrs, and replace it if necessary. A dull or bent needle breaks thread more often than any other cause.

What is the take-up lever and why does it matter?

The take-up lever is the small metal arm that moves up and down on the left side of the needle. It controls how much thread is released with each stitch. If you skip it during threading, the machine cannot regulate thread tension, and your stitches will fail. Always thread through it.
