While sewing my top thread ran out and now my machine is 'locked up". I took out the bobbin thread and case, but I need to unblock or release something there.

    My machine is maintained very well. I need to know if there is a 'release' somewhere to free the thread that has it locked up.

Hi rhix92,

Please try to consider doing the steps below.

1. Try to re-thread your sewing machine. Please make sure that the thread is in the tension guides, as well as in the take up lever.

2. Now, raise your feed dog if you are piecing and not quilting.

3. Hold both the bobbin and needle thread tails in your fingers as you begin a line of stitching. This will keep the tails from tangling on the underside.

Hope it helps.

Thank you for using FixYa.

Hi, there three reasons why sewing machines lock up. Sewing machines lock up because of neglect. Sewing machines lock up because of a fluke in the bobbin area. Sewing machines lock up because of broken parts.
The most common cause of a locked up sewing machine is neglect. Sewing machines require periodic service. Old oils and grease dry out and crystallize. Use of the wrong oils can cause a sewing machine to lock up. Many oils have paraffin or other ingredients that are harmful to the sewing machine. Old Oils, grease, debris must be removed. The sewing machine requires proper lubrication. When the sewing machine maintenance is neglected, it will eventually lock up.
Flukes can happen in the bobbin area. Often the fabrics or threads used can cause problems in the bobbin area. If thread gets trapped in the race of the hook, the sewing machine will lock up. If you use very linty fabrics, the lint can bunch up in the bobbin area and cause it to freeze. Sewing machines can also lock up when a part inside the sewing machine breaks. If a gear breaks a cog, it can lock up. If a lever bends, it can lock up. If a cam assembly breaks, the sewing machine can lock up.

    When you attempt to turn the hand wheel, the sewing machine is locked up or dead head. First, remove the bobbin and bobbin carrier. If the hook assembly is removable, take it out. Test by turning the hand wheel. If it is loose, the problem is gunk in the bobbin assembly.

    Remove all the covers. Test the hand wheel while observing the insides of the sewing machine. Watch the upper shaft. Examine the lower shaft. Look for any points where metal touches metal. Look for any broken parts.

    Remove all debris, old oils, and grease. Thoroughly clean the upper and lower sewing machine. Use carborator cleaner or similar chemical to dissolve an old sticky and gummy lubricants. Use chemical cleaners as necessary. Test the hand wheel again. Beginning at the hand wheel follow the drive mechanisms across the upper and lower parts of the sewing machine. Force the hand wheel to turn even a slight amount. Find the points of resistance.

    If you find a bind between metal parts that just won't give, add lubricant. Move the pieces back and forth to loosen and free them. Work the binding areas until they become free. In extreme situations, you may use a torch or soldering iron to heat up a binding point. The heat will dissolve the old lubricants and enable you to free the bind.

Everytime i start the machine, it will sew great then, i have 2 or 3 strings from the bobbin and usually ends up locked up

Sounds like the bobbin thread is not under tension correctly or is in the wrong way around.

Remove the bobbin case and bobbin from machine and check that the thread is clipped in under the tension spring. Then do the "Dangle" test. If you suspend the bobbin case by holding the thread end and the case dangles in the air, it should "stay" in position, i.e. not drop down the thread releasing more thread. But if you gently tug the case you should be able to pull it down releasing thread without applying significant pressure. Adjust the tension on your bobbin case by turning the tension screw just one "quarter turn" each time until you get the tension set correctly so you can "dangle" it.

Then place back into machine and rethread the top.

Also good practice to always hold both top and bottom threads at the back of the needle plate when you start stitching until the seam has been started.

Not picking up the Bobbin thread

I cleaned the machine good with canned air, oiled it. I took out the bobbin case and cleaned it good also. I then noticed the tension screw on the bobbin case was loose, tightened it and the problem was fixed.

Sewing Machine CS-8060

I do have the very same problem! I took my bobbin case out and took a good look at it, turns out right below the plastic hook part, the plastic was cracked off (probably due to thread jamming). Turns out I need a new internal bobbin case, which range in price from $35-$50 from what I researched. I had no luck with local sewing centers on finding the part.
That may (or not) be your issue as well. Good luck, and I hope this your issue is simple fix. A little tune up after might be needed, HAPPY SEWING!! ~Kelly J~

Janome 9000

I have a Janome 9000, was sewing and broke needle, replaced and broke another. I didn't have machine threaded, took out bobbin and would sew a little and stop saying thread broke. I took off top plate and started machine again, sew a little and stop saying thread broke. So I took out bobbin case and sewed again and stopped repeating the message. Everything looks OK, bobbin case and top plate. I guess I want to know if the timing could be off or do you think it is the computer part of the machine...Should I take it to the Sewing Machine Shop??

Threading the Bobbin

Place the bobbin in the bobbin case making sure the thread feeds clockwise. Draw the thread through the slot on the case. Continue to draw under the tension spring and through the opening pulling out about 6" of thread. Hold the latch open, position the bobbin case into the suttle and release the latch. THe case should lock into place when the latch is relaeased.

With the top thread, hold out about 5" to the left. While holding on tot he top thread, turn the hand wheel toward you and you should see a loop at the feed dogs. grab the two thread and bring them behind the presser foot.
