The Singer 5050c has slowed down and doesn't run very fast? Could this be a belt proble? Or Foot presser problem? Or a motor Problem

If the presser foot isn't connected to the presser foot shank, place the foot under the center of the shank. Lower the presser foot lifter making sure that the shank goes over the presser foot pin. Press down firmly on the screw that holds the presser foot shank until you hear the foot snap into the shank. Do not turn the presser foot shank screw. See the pictures on page 9 of the manual (page 11 of the PDF). Manuals LIb has this page here https://www.manualslib.com/manual/470415/Singer-7033.html?page=11#manual . The manual is also available from Singer on their support page: https://www.singer.com/support . The direct link to the manual is https://www.singer.com/sites/default/files/product_manual/SINGER%207029_7033_%207035%20and%209410%20Sewing%20Machine.pdf . For feet that are attached to the slant shank, you loosen the presser foot shank screw. Place the shank over the presser foot screw and then tighten the screw to hold the presser foot. If you removed a foot and the shank together, put it back on. Make sure that the needle and the presser foot lifter are in their highest positions. Push up the front side (toe) of the presser foot until the foot snaps off the shank.

If the presser foot doesn't snap into place, make sure that you have everything aligned properly. Otherwise check for damage to the presser foot and the shank. Replace any damaged parts. Some presser feet are available here: https://www.sewingpartsonline.com/singer-7033-sewing-machine-parts.aspx .

I hope this helps.

There may be a disconnection between the lever and the presser foot bar. Perhaps a screw has fallen out, broken, or is loose? May need to take it for service.

what type of machine do you have. I have two that I operate with buttons and it has a little slide button to speed or slow down I don't know why it should run to fast with a foot pedal because you control the speed with your foot you may want to check to see if there is any trash that has gotten in the foot and somehow not allowing the foot to come back up

You don't say whether your machine is newer or an antique. The model number would really help your helpers help you.

Let's work on your vocabulary a bit: A presser foot, is what holds the material down so the feed dogs and move it through the machine. The foot pedal is pressed to make the machine go. ;)

However this sounds like a machine that needs service... by your explanation of how you change the speed to fast and run it fast... it sounds like one of the modern electronic machines. Since modern machines don't have oiling and greasing guidelines I suspect your machine I well overdue for servicing. Find your local sewing machine tech and take it in. Ask for a "Clean, Oil and adjust timing" and be sure to mention the motor issue. While he's there ask him to check the belts and replace if necessary.

Good luck.

Hello there! Make sure your pattern selector is compatible with the presser foot. Good idea to test with a straight stitch setting: Tension: 4. Width:4-5. Length 5 after you insert a new needle and re-thread machine. Your previous needle may have become bent when machine malfunctioned. Use fabric compatible with needle size. Always raise presser foot when threading! Then always lower presser foot before sewing. Remember to use blue tip scarf needles with synthetic fabric silk thread 50. Purster thread 50, mercerized cotton thread 50-60; #11 or #9 for fine or lightweight fabric with silk thread 50 or fine Pollyester thread; #18 leather needle for leather, #14 - 16 denim . Jimmy Sweep out shuttle carefully with small brush for broken threads and lint.

Call Singer customer service at 1-800-4singer and it could be a computer board problem, if your speed control switch is in the right position

There is no speed adjust, but 1st you must know the source of the slow down. Remove the belt from the motor pulley and run it, if it goes fast try turning the hand wheel if it is stiff the machine needs clean and oil. If it turns freely you motor may be dirty or just slow. If dirty, sometimes you can without the blet attached run it at full speed for 10 to 15 minutes. It should get faster as you run it. If not motor is weak or slow needs replace. Just replacement motor as genuine probably no longer available.

Make sure to thread machine with the presser foot raised. Then make sure thread gets in between the tension discs and that you have the machine threaded correctly with the thread going up and into the take-up arm. tension should be set at 4-5.

Hi,
By removing the top cover, or the turning wheel cover,
you will be able to see the belt.
If the belt is not broken, then try to adjust the belt tension,
by adjusting either the height of the motor, or the tension wheel.

check the foot peddal that it is not sticking if it is take it down and service it.if that does not work the motor needs to service also or replace.goodluck.
