Sears GDO: won't open completely
I recently had to readjust the up limit to keep from
binding on the bolt. Worked great a few days. Now it
will not open all the way -- about 8 inches shy. If I
run it down just a bit, then back up, it often goes all
the way up. Have played with the up force (max) and up
limit (no effect).
Could this be old rails binding old trolley wheels
on the door??
