Simplicity so5 needle wont move

How long has it been since it's had a thorough cleaning & oiling (including the internal moving parts)? Resist trying to run the machine if the only thing running is the motor. You could burn up the motor or possibly break a gear.

The following method has helped me rescue some frozen older Berninas (which your model seems to resemble). This method worked on all of them except one that also needed a cracked gear replaced.

Wheel on right side that controls the needle up and down is very tight...

It was working now it seems to be frozen the needle part wont move

In free motion you move the fabric by hand after dropping the feed dogs

You need to look into the bobbin case for rags and thread. Clean this carefully. Check for rags and thread that is stuck in the feed dogs. You may need to move the hand wheel backwards and forwards to get it going again. Once you get it moving check those areas you previously checked again. Before you put the bobbin case back in place a drop of oil on the race track.

when was the last time the machine was serviced?

change the needle
clean under the needle plate & in the bobbin area for loose threads & lint
rethread the machine top & bobbin

Is this a result of you having a problem? One of two things

1) You knocked the clutch out, check you manual on locking the timing back in
2) You knocked the timing off enough that the bobbin hook isn't picking the needle thread up.

Look at the bobbin area and slowly spin the hand wheel. Does your bobbin hook move at all? If it is moving look to see if the hook passes the needle just as the needle begins it's upward journey.

Good Luck!

It sounds like one of your clearances in the machine is off. When a machine skips stitches like yours is doing, it does so because the hook responsible for "catching" the thread from the needle is not close enough to the needle so it misses the loop of thread from the needle. If your machine was having a timing problem it wouldn't sew well on any fabric. A clearance problem shows up on certain fabrics at certain times. A few things you could do to try to compensate it would be to use a slightly larger needle and turn your top tension dial down to a lower setting. Move the machine a little slower on the frame or increase the speed of the machine. Either way a trip to your technician will be needed. Make sure you tell him to check the needle to hook clearance.

Check your needle. Make sure it is not blunt, try a Size 90 Topstitch needle or Embroidery needle. If you are using a thread thicker than regular piecing weight, you need a needle with a larger eye and a larger scrarf - the hollowed out bit at the back of the needle. Also don't sew too fast nor change direction too sharply. If you need to do a sharp turn, let the machine "mark time" once at the turn before moving off in the new direction.

Try practicing on a test piece before moving on to the quilt. Batik fabric is beautiful! I would check the thread size and needle. I tried quilting with invisible thread and had the same problem. The minute I changed to 50 wt.thread and a new needle the problem disappeared. I've found that 40 or 50 wt. thread works best on my Janome.

using a pair of needle nose pliers grasp the needle as far up as you can and pull down. Sometimes a slight twist will help.
