Threading a Kenmore sewing machine takes about five minutes once you know where each part goes

Kenmore machines thread in a specific order: upper tension discs, tension dial, take-up lever, guide, needle, and finally the bobbin area. The most common mistake is skipping the tension discs or threading the needle from the wrong direction — both cause loops and skipped stitches. This guide walks you through the exact sequence for a standard Kenmore model, with the presser foot up (this opens the tension discs) and the needle in its highest position.

Before you start, gather a fresh needle, thread, and a small pair of scissors. If your machine has been sitting unused, the old thread may have dried out or frayed — replace it even if there is thread already in the machine. A clean bobbin also helps; lint buildup in the bobbin case causes tension problems that look like threading errors.

Key Takeaways

  • Always raise the presser foot before threading — this opens the tension discs and lets thread slip between them.
  • Thread must pass through the take-up lever on its way down to the needle, or the machine cannot form proper stitches.
  • The needle goes in from the flat side facing the direction shown in your machine's manual, usually with the flat side toward the back or left.
  • If stitches loop on top, the upper thread is too loose; if they loop underneath, the bobbin thread is too loose or the upper thread missed a guide.

Raise the presser foot and position the needle at the top

Lift the presser foot lever (the hinged arm at the back of the needle area) all the way up. You will hear or feel a small click. This action opens the tension discs — two metal plates inside the machine that grip the thread. If the presser foot is down, the discs stay closed and thread cannot pass through them, which is the single most common threading mistake on Kenmore machines.

Turn the handwheel (the large wheel on the right side of the machine) toward you until the needle reaches its highest point. The needle should be all the way up. This position makes it easier to insert the needle and prevents it from hitting the presser foot or thread guides as you work.

Thread from the spool to the tension discs

Place the thread spool on the spool pin at the top of the machine. The spool pin is usually at the top right or top center, depending on your Kenmore model. If your machine has a spool cap (a small plastic disc), slide it onto the pin to hold the spool in place.

Pull thread from the spool and guide it down toward the tension discs. Look for the first thread guide — a small hook or loop near the top of the machine, usually just below or to the side of the spool pin. Thread the line through this guide. Then continue down to the tension discs, which sit in the center-front area of the machine. Slide the thread between the two metal discs. You should feel slight resistance as the discs grip it.

Route thread through the take-up lever and remaining guides

The take-up lever is a metal arm that moves up and down as you sew. It sits to the left of the needle and has a small hole or hook at its tip. Pull the thread up and through this hole. This step is critical — if thread skips the take-up lever, the machine cannot form stitches correctly, even if everything else is threaded perfectly.

After the take-up lever, thread continues down through any remaining guides on the front of the machine. Most Kenmore models have one or two more small guides between the take-up lever and the needle. Thread through each one in order, moving downward. These guides keep tension even and prevent thread from tangling.

Insert the needle and thread the eye

Kenmore needles insert from a specific direction — check your manual for whether the flat side faces left, right, back, or front. Most Kenmore machines use needles with the flat side facing the back or left. Loosen the needle clamp (a small screw or lever above the needle) and slide the needle up into the clamp as far as it will go, with the flat side in the correct direction. Tighten the clamp firmly.

Pull the thread down and through the needle eye from front to back (or the direction your manual specifies). Leave about 4 to 6 inches of thread hanging below the needle. This tail of thread is important — it prevents the thread from slipping back out of the needle as you begin sewing.

Wind and insert the bobbin

While the upper thread is now in place, the bobbin (the small spool that holds thread underneath) must also be wound and inserted. Wind thread onto a bobbin using your machine's bobbin winder — this is usually a small spindle on top of the machine. Follow your manual for the exact winding process, as it varies by model. Wind until the bobbin is full but not overstuffed.

Insert the wound bobbin into the bobbin case. On most Kenmore machines, the bobbin case is a small metal or plastic box below the needle. Open the case, drop the bobbin in, and thread the bobbin thread through the small slot or guide in the case. Close the case. Some models have a drop-in bobbin that sits directly under the needle; others have a removable bobbin case that slides into a shuttle. Your manual will show which type yours is.

Bring up the bobbin thread and test the tension

Hold the upper thread tail in your left hand. Turn the handwheel toward you one full rotation. As the needle goes down and back up, it will catch the bobbin thread and pull it up through the needle plate. You should see a loop of bobbin thread appear on top. Pull gently on the upper thread to bring the bobbin thread all the way up, then pull both threads to the back and left, away from the needle.

Sew a test seam on scrap fabric using the same thread and needle you will use for your project. Stitches should look even on both sides — no loops, no puckering, no skipped stitches. If the top side has loops, the upper thread is too loose or missed a guide; rethread the upper thread and check that it passes through the take-up lever. If the bottom has loops, the bobbin thread is too loose or the bobbin is wound unevenly.

Common threading mistakes and how to fix them

Loops on the top of fabric: The upper thread is either too loose or did not pass through the tension discs or take-up lever. Rethread from the spool, making sure the presser foot is up and the thread slides between the tension discs with a slight click. Verify the thread passes through the take-up lever hole.

Loops on the bottom of fabric: The bobbin thread is too loose, the bobbin is wound unevenly, or the bobbin case is not inserted correctly. Rewind the bobbin, making sure it is wound smoothly and tightly. Check that the bobbin case is fully closed and the bobbin thread is threaded through the slot in the case.

Thread breaks while sewing: The needle may be bent, inserted backward, or the wrong size for your fabric. Replace the needle, making sure the flat side faces the correct direction. If you are sewing heavy fabric, use a heavier needle (size 16 or 18 instead of size 10).

Needle keeps hitting the presser foot: The needle is not in its highest position. Turn the handwheel toward you until the needle reaches the top before you start sewing.

Frequently Asked Questions

Does the presser foot have to be up to thread the machine?

Yes. The presser foot lever controls the tension discs. When the foot is down, the discs clamp shut and thread cannot pass through them. Always raise the presser foot before threading, even if you are just changing the needle.

What if thread keeps slipping out of the needle?

Leave a longer tail of thread hanging below the needle — at least 4 to 6 inches. As you begin sewing, hold both the upper and bobbin thread tails to the back and left for the first few stitches. This prevents the thread from sliding back out of the needle eye.

Can I thread the needle from back to front instead of front to back?

No. Kenmore needles are designed to catch thread from one direction only. Threading from the wrong direction means the thread will not sit in the groove of the needle, and stitches will skip or break. Check your manual for the correct direction for your model.

How do I know if my bobbin is wound correctly?

A correctly wound bobbin should be smooth, firm, and evenly filled — not loose or lumpy. If you see gaps or uneven spots, rewind it. Wind slowly and steadily, and stop when the bobbin is full but not overstuffed. An overfull bobbin can jam in the case.

Why do my stitches look different on the top and bottom even after rethreading?

Uneven stitches usually mean one thread is looser than the other. If the top looks loose, rethread the upper thread and check the tension dial setting. If the bottom looks loose, rewind and reinsert the bobbin. If both look correct but stitches still pucker, try a lighter needle or reduce the tension dial by one or two numbers.
