My pfaff 1221 sewing machine has frozen. I was sewing at the time and it slowed down and then stopped. Needle won't come to upright position when I hit the lever behind the foot

SOURCE: Doesn't sew

Hi emnsam....please update your post with the complete Model Number in it's entirety and I will be able to advise you.

SOURCE: Machine slows down,stops, starts again. Foot control problem?

Yes it does sound like a faulty foot control. The power cord is probably fine, you just need the controller. Ebay is a good source for parts.

SOURCE: The thread is bunching up

Your problem stems from the faulty foot lever mechanism. It's coupled to the upper thread tension control which only provides tension when the presser foot is in the locked down position.

If the presser foot won't positively engage in the down position, there's no upper thread tension and the thread bunches up below. Everything else stems from there. If the needle has hit the bobbin case too frequently then the bobbin timing may also be slightly out and the needle itself will be damaged and won't pass straight through the fabric; it only takes a tiny deflection from the vertical as it passes through the workpiece for the needle to flex and hit the bobbin case.

In summary, your machine is in desperate need of repair and adjustment. You haven't stated which exact Singer model you have, but they are usually easy to get servicing manuals for or you can take the machine to a sewing machine servicing specialist. Most singer spare parts (even for 100 year old machines) are usually still available fairly cheaply from a variety of sources, just enter "Singer spares" into your search engine to find suppliers.

To prevent re-occurrence, clean the mechanism regularly and lubricate it as directed by the manufacturer using sewing machine oil. Depending on how often you use the machine, do (or have done) a more thorough service periodically to check the timing and also that all mechanism screws remain tightly fastened.

I hope that my reply has shed some light on your problem and enables you to decide what to do next. Please take a moment to rate my answer.

I had this same problem. On the bottom of the head there is a slide switch. Lay your machine on its back and you can easily see it. Slide it back and your problem should be solved.

I had the same problem and it was my power supply. I've had more than my share of problems with this machine and it's only 3.5 years old. Good luck.
