Welcome to Quilting Board. The 15-91 is a great machine. I hope you can find someone. A lot of us on here clean and oil our own machines. There is an adjuster's manual for the 15-91 at if you are so inclined to try to get it running yourself. A regular manual for it can be found at
Sometimes it takes some time to get it running smoothly. As I was told - "It took a long time to get in the condition it is in - don't expect immediate results."

We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a file size that is smaller than 2MB. How to post images can be found at
Don't forget to scroll over to the far right to find and click on the "Upload" button.

I have found that only the big red "Reply" button or "Quote" work to give me the paper clip icon to work for adding pictures.

Some additional info regarding reducing images at post #4 and images for the scroll and upload button can be found at #5 of quilt block ID?

Another way to post pictures can be found at 2021/2022, 2.5Ē Birthday Swap
And how to use an ipad to post pictures can be found at Uploading photos

Or simply - Make sure pictures are smaller than 2MB
Click on red "Reply" button
Click on the paper clip icon
Click browse - choose picture/s. (only 5 allowed per post)
Once they show up as being loaded, Scroll over to the right side and click on "Upload"
After the pictures show up as being attached, you can close that window and go back to the screen to finish posting your post.

Default Singer 15-91

I recently was gifted a 15-91. It too was frozen. I learned that the motor is called a potted motor, which has grease wicks to lubricate the bearings. The grease was old and stiff. There was a slight movement when I tried to turn the hand wheel. After removing the hand wheel, I found a nylon like gear around the hand wheel that has springs inside it. The motion I was experiencing was just those springs, as the motor didn't turn. If I had tried to free the machine up by working the hand wheel back and forth, I could have easily damaged the gears!
The motor has grease wicks in it. I had to buy feet to get inches of this wicking. If you or your repair guy needs new wicking, PM me and I can send you some. I have way more than I will ever use.
Don't let anyone try to force the machine to turn using the hand wheel. If you take the hand wheel off, that disengages the gears, so you then try to turn the machine itself. If it turns, the problem is in the motor. It is very important not to damage the motor, as they are hard to find and pricey.
Good luck with it. They are great machines!
