Motor is spinning- needle not going up and down.

All questions need full 'make model (what it is)' please. This is what I get trying to search your issue.

It sounds like a professional embroidery machine. One of the linkages has come loose. They are timed by small set screws in the knuckles. When was it last serviced?

..

Most likely the old oil has dried out and preventing the parts from moving. Avoid using it until the problem is addressed or the motor could be damaged.

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

Sounds like the motor belt is off or broken.

good luck!

Is the needle going up & down?

If so, remove the thread.

Replace the needle with a brand-new needle.

Clean any lint/debris from the bobbin area, feed dogs, under the needleplate. Oil as recommended in the owner's manual.

Always RAISE the presser foot when threading. Rethread the machine from the beginning and verify the thread path is correct.

Retest the machine.

If it is still not picking up the bobbin thread, there is probably a needle/hook timing issue. Take it for service.

If the needle is not going up & down, something in your machine has seized. Resist the urge to run the motor when the machine parts are not operating. Depending on your machine make/model (if it is mechanical, it probably could use a good service cleaning & oiling), if it is a computerized machine, you should probably take it for professional service.

This could be the needle bar clutch. Turn off machine. Unplug machine. Remove needle. Turn hand wheel in normal rotation 1/4 turn. Gently move needle bar up and down by hand you should feel a click and the needle bar will not move up and down easily now. Restart machine and test. If it works all is good. This is a result of the machine requiring professional attention. If you use basting stitches it will likely unclutch again.

try turning the bobbin in the opposite direction & see if that helps

Well, AC/DC motors do "seizing" quite well in fact.

If you were supposed to oil it prior to the failure, they most likely will not work now! (Bearings are shot)

BUT.....Lady Luck is always hiding, so you never know.

Tear that dude down, and give it some 7-in-1 oil. Spin the motor BY HAND. See if she will "free spin". If she feels like a 6 year old fighting a catfish, it will be a "no go, no fix".

But if she WILL spin after that......give her a couple of drops extra, put it back together, and see how long she lasts.

And then keep on oiling it.

Granted, I can't tell you exactly WHAT seized your sewing machine up, OTHER than motors are motors, and bearings fail when they get dry. In this case, you might get lucky!

i have an elna model 62C supermatic purchased in 1972. on yours, do you mean the motor won't run at all? or does the electronic foot not cause a response to sew? after 30 years, in 2002, my electronic foot quit working. i opted to purchase the internal electronic module, and replaced it into the original housing (did it myself). the two weak spots in an otherwise amazing machine are the two plastic gears--rotary hook gear which works your bobbin, and the camshaft stack gear which works cams/zigzag/etc. i have replaced both in the last 5 years (again, did it with my husband's help). i'd say the Elna is pretty awesome sewing machine with the couple of million hours i've used it (no exaggeration!) and the minimum of repairs it has needed. an excellent source of parts is www.whitesewingcenter.com. parts are reasonable, and authentic. Raymond White is extremely helpful and knowledgeable. good luck. jeannie

YOUR PROBLEM IS THE TIMMING IN YOUR MACHINE. THIS HAPPENDS WHEN YOU FORCE YOUR MACHINE TO SEW SOMETHING OR WHEN YOUR NEEDLE BRAKES. nOT SURE HOW TO FIX IT. I HAVE THE SAME PROBLEM. USUALLY A TUNE-UP WOULD DO IT. IT'S ABOUT $99 TO $130.00 TO DO A TUNE UP. i WISH I KNEW HOW TO FIX IT MYSELF.

Practically every machine made in the last 50 years uses a 15x1 needle also known as 130/705 universal fit.
