I installed a Sears screwdrive garage door opener about 18 months ago and
it's worked great up until last week. Symptons were that the screw drive
made a lot of noise and failed to pull the door up. I could push the
'connector car' up and down the track so assumed the internal mechanism that
ride on the screw threads was shot.

I order a replacement and I installed it tonight (the old one was obviously
stripped) however the opener has developed or also had a different problem.
When on and disengaged from the door the screw itself is making a heck of a
noise - it is almost like it is lose in it's tunnel and is 'thrashing
around'. I disassembled the support beam (it is made up of 3 pieces) and
looked at the screw - which seems fine. It runs inside a plastic tunnel -
which also looks fine. I've checked the beam and it seem straight and true.
Any thoughts are appreciated.

I assume that the new screw came with a tube of grease, and that you
used the whole thing? My Sears screwdrive garage door opener gets
cranky every winter, but the grease seems to help.

If yours didn't come with any and you can't quite get yourself to the
hardware store, see the very bottom of

I use a synthetic bicycle grease - it is easy to find at any bike shop
and it works fine.

Thanks for the suggestion - I've greased it well. I don't think that is the
issue.

first check and see if the section nearest the opener is turning
normally -the opener has double female interconnect between the male
hex drive on 1st screw section and motor drive- if undamaged then
problem is likely screw section binding clips. inspect the junction
points where the screw sections combine. there should be a barrel that
slides up from the long throated side to marry the 2 pieces and a half
barrel that then snaps under it so it can not slip down.if you lost a
clip and the barrel is free to travel the noise will be generated by
slop and only thing holding screw pcs together is the confines of the
housing.
