Threading a Kenmore sewing machine: the basic path
Threading a Sears Kenmore sewing machine follows the same order every time: bobbin case, presser foot, tension discs, take-up lever, guide, needle. The machine will not sew properly if you skip a step or thread in the wrong order, even if the thread looks seated. Most Kenmore models use the same threading path, though older machines and specialty models may vary slightly — check your manual if you have one, or look up your specific model number online.
The most common mistake is threading with the presser foot down. The presser foot must be up before you thread, because raising and lowering it opens and closes the tension discs. If you thread with the foot down, the thread will not sit between the discs, and your stitches will be loose or skip.
Key Takeaways
- Raise the presser foot before threading — this opens the tension discs so thread can seat properly between them.
- Thread in this exact order: bobbin case, presser foot area, tension discs, take-up lever, guide, and finally the needle.
- Pull thread gently through each guide and the tension discs; you should feel slight resistance as it passes through the discs.
- If stitches are loose or skip after threading, the thread probably did not seat in the tension discs — rethread with the presser foot raised.
Step-by-step threading for Kenmore machines
Step 1: Raise the presser foot and bobbin case. Lift the presser foot lever on the back of the machine. Open the bobbin case cover on the front (usually a small hinged door or removable plate). Insert a wound bobbin into the case, following the threading slot marked on the case itself. Pull the bobbin thread up and to the left, then under the tension spring, and leave it loose for now.
Step 2: Prepare the needle area. Raise the needle to its highest point by turning the hand wheel toward you. This positions the take-up lever at the top of its cycle, where it is easiest to thread. Make sure the presser foot is still up.
Step 3: Thread the top path. Place a spool of thread on the spool pin at the top of the machine. Pull the thread down and to the right, guiding it into the first guide (a small hook or notch near the spool pin). Continue down to the tension discs — you will see two metal discs with a narrow slot between them. Push the thread firmly into this slot; you should feel resistance. Pull the thread down and to the left into the next guide.
Step 4: Thread the take-up lever. Follow the thread down to the take-up lever, a metal arm that moves up and down on the right side of the machine. Pass the thread through the hole or slot in this lever from left to right. This lever controls the amount of thread fed to the needle and must be threaded or stitches will not form.
Step 5: Thread the needle. Continue down to the needle guide just above the needle, and pass the thread through it. Finally, thread the needle itself from front to back (or left to right, depending on your needle orientation). Leave about 6 inches of thread hanging below the needle.
Step 6: Bring up the bobbin thread. Hold the top thread with your left hand and turn the hand wheel toward you one full rotation. This causes the needle to go down and pick up the bobbin thread. Pull gently on the top thread and the bobbin loop will come up through the needle plate. Pull both threads to the back and left, under the presser foot, and you are ready to sew.
What to do if the thread does not seat in the tension discs
If you thread the machine and the top stitches come out loose or the thread breaks, the problem is usually that the thread did not pass fully between the tension discs. Rethread the top path: raise the presser foot, pull the thread out of the tension slot, and push it back in firmly. You should hear or feel a small click as it seats. If the discs feel sticky or the thread will not stay, the discs may need cleaning — use a small brush or compressed air to remove lint buildup.
If the thread keeps slipping out of the discs, check that you are using the correct thread weight for your machine. Very fine thread (like 60-weight) or very thick thread (like topstitching thread) may not seat properly in standard tension discs. Kenmore machines are designed for standard 40-weight or 50-weight thread; if you are using something different, you may need to adjust the tension dial or use a specialty presser foot.
Bobbin threading and tension
The bobbin thread path is shorter than the top thread path, but it must be threaded correctly or the machine will not form stitches. After inserting the bobbin into the case, pull the thread up and under the tension spring — this is the metal clip inside the bobbin case. The thread should sit snugly under the spring so it does not slip during sewing.
Once both threads are in place, lower the presser foot. This closes the tension discs on the top thread and prepares the machine to sew. If you forget to lower the presser foot before sewing, the top thread will not have tension and stitches will be loose. Many sewers develop the habit of checking the presser foot position before every project, because this single step causes most tension problems.
Older Kenmore models and variations
Kenmore machines made before 1980 may have a different threading path, especially if they are slant-needle or straight-stitch models. The bobbin case may be built into the machine rather than removable, and the tension discs may be in a different location. If you have an older machine, the manual is your best resource — Sears sometimes made model-specific variations that do not follow the standard path.
Some Kenmore models have an automatic needle threader, a small hook that catches the thread and pulls it through the needle eye. If your machine has this feature, raise the presser foot, place the thread in the guide above the needle, lower the threader lever, and it will pull the thread through. Even with an automatic threader, you still must thread the bobbin case and tension discs by hand.
Common threading mistakes and how to fix them
Skipped stitches or loose top stitches almost always mean the thread is not seated in the tension discs. Rethread the top path with the presser foot up, making sure the thread passes fully between the discs. Broken thread usually means the thread caught on a burr or rough spot in the needle or guides — check the needle for damage and replace it if needed, then rethread.
If the bobbin thread breaks or the machine makes a grinding noise, the bobbin case may not be inserted correctly. Remove the bobbin case, check that it slides into the slot smoothly, and make sure the thread is under the tension spring. If the case is damaged or the spring is bent, the bobbin case may need to be replaced — Kenmore sells replacement cases for most models.
Frequently Asked Questions
Can I thread the machine with the presser foot down?
No. The presser foot must be up to open the tension discs so thread can seat between them. If you thread with the foot down, the discs stay closed and the thread will not pass through properly, causing loose or skipped stitches.
What if I cannot get the thread through the tension discs?
Make sure you are pushing the thread firmly into the slot between the discs, not just laying it on top. You should feel resistance. If the thread still will not go through, the discs may be clogged with lint — use a small brush or compressed air to clean them, then try again.
Do I need to rethread if I change the thread color?
You do not have to, but many sewers do. If you leave the old thread in place, it may show at the edges of your stitches. To avoid this, cut the old thread, tie the new thread to it, and pull the new thread through the machine — this saves time and thread.
Why do my stitches look loose on top?
Loose top stitches mean the top thread does not have enough tension. Rethread the machine with the presser foot up to make sure the thread is seated in the tension discs. If that does not work, the tension dial may need adjustment — turn it slightly higher (toward the higher numbers) and test on scrap fabric.
What is the take-up lever and why does it matter?
The take-up lever is the metal arm that moves up and down as you sew. It controls how much thread is fed to the needle with each stitch. If you skip threading it, the machine will not form proper stitches. It must be threaded every time you thread the machine.
