Kenmore sewing machine 15008100 not working

Use a new different bobbin...plastic bobbins are notorious for melting and then don't work. Also, take your time winding the bobbin...a nice even wind will center the bobbin. Speed demons cause the bobbin to be unevenly wound and off center. Good luck!

It sounds like the lower shuttle is out of place. You should be able to take out the bobbin case and unlatch the shuttle. It will probably be in 2 pieces. Clean out the dust behind it and replace the shuttle pieces. You may have to fiddle with it a little to get them back in place. Then you can test it by manually turning the wheel. Make sure the bobbin is placed into the bobbin case and that the bobbin turns in the direction that you pull the thread.

Good luck.

best suggestion try inserting new needle. cotton up the top suggests needle problem or incorrect top thread tension, this would effect the feed dog. Because thread is black and most recent use was with pink, the problem thread was already there perhaps in cavity above bobbin but below throat plate. I have had this happen and nothing will move, untill needle released. The bobbin holder tension may also need adjusting after the knots of black cotton are removed.

Hello,

Open the bobbin cover and remove the bobbin from your machine. Examine the bobbin case and make sure there aren't stray threads jammed into any grooves. If you see clumps or strands of thread, remove them with your fingers or with tweezers.

Look over how the bobbin is positioned in the case and whether or not it is inserted correctly. Different machines hold the bobbin in different ways and some machines don't use a bobbin case. Consult your machine's manual for the proper way for its bobbin to be inserted.

Make sure the thread is wound evenly on the bobbin. If your thread has large sections of loose loops sticking out from the rest of the thread, they easily could be causing the problem. Rewind the bobbin, if needed.

Clean the shuttle mechanism and the bobbin case with a small soft brush, such as a make-up brush, and a dust cloth. Remove as much dust and tiny fiber pieces as possible. Resist the urge to blow into the machine to clear away dust, this can send debris farther back into the machine, causing more serious problems.

Oil the movable pieces of the shuttle by putting a few drops of sewing machine oil on a Q-tip and rubbing the Q-tip over the hinge-like turning areas. Do not add too much oil to the machine; one drop goes a long way.

Reload your bobbin into the machine and sew a line along a piece of scrap fabric. Check your thread tension and adjust it as needed following the manufacturer's instructions. The upper thread should never show through the bottom and the bobbin thread should never show through the top.

I hope this helps to solve the problem.

Good luck.

sounds like it needs a service call. if you do not have a sewing repair man you use regularly to clean machine the local fabric store should know who you could call.

bobbins in backwards
flip it over

Sorry to say but one of your steps is incorrect. Look at it again, take a deep breath and gom
over everything slooowly. If this really doesn't work then Im afraid it's a technician you need :) .

Hello ZAckofun
The shuttle hook will be covered by a plate called the RACE. Its a flat steel plate that sits over the hook and is snapped in place by 2 black coloured snaps.
Looks like you are trying to operate the machine without the race on. try that and it should work.
