Sewing Machine Won't Sew in Reverse?

My Elna 3007 became temperamental at sewing in reverse some years ago. On occasion, I will need to push the button more than once in order to make it sew in reverse. Just recently, it stopped sewing in reverse completely. So I inspected the bobbin case and area and cleaned quite a bit of lint out of it. It began to sew in reverse again. I thought it was fixed. Now, a week later, it no longer sews in reverse.

I see that there is similar question about this matter from another member, and the answer is that a gear is broken. If a gear was broken would it be able to sew in reverse sometimes and not others, like mine has over the years, and did again last week?

A 'broken' gear on a modern electric doesn't mean the same thing as a 'broken' gear on a sewing machine built when all parts were made from cast iron and steel. 'Modern' electric sewing machine have a number of gears made from rubber, silicone, and plastic - if the teeth on those gears are worn just a bit the teeth will catch if there is enough of the synthetic material left on several teeth - the stop-start motion in sewing will force the wornish bits on until the remaining teeth catch.

But sooner or later (and only slightly later in some cases) the remaining teeth will wear as well. A repair tech (I do vintage machine repair) will simply say the gear was broken rather than use the word 'worn' although some will say 'worn' straight off.

Bottom line is - your gear is going/gone and you need to take your machine to a repair tech.
