I have a torsion spring garage door. A few days ago, the door would
not close and would make a grinding noise. I noticed that one of the
rollers was missing at the top of the door. After replacing the
roller, the door rises smoothly, but when it is being let down, I still
hear the grinding noise and there appears to be quite a bit of tension
on the arm that extends from the track to the base of the opener unit.
It does go down, but something is not right.
The door itself is quite heavy, as it's a 2-car garage and the door is
Does this sound like a track cleaning issue or something simple that I
can adjust on the unit, or does it sound more involved than that?
I can email a short mpg from my digital camera if it would help.
Many double-wide doors actually have two springs rather than just
one...possibly one is broken leading to a mismatch/alignment problem of
which the noise is just a symptom. Also possible that the roller failed
independently but something has gotten out of whack owing to the
problem. If you can't tell what is binding, probably need an
experienced door mechanic to diagnose/fix the problem.
There should be a release mechanism on your opener, an arm right
where it attaches to the door, with a red pull string typically.
Release the operator. If you can raise and lower the door (yes,
that's how we old folks used to do it before operators) with out
binding or problems, the noise and hassle are in the operator. If
you cannot raise and lower the door, the problem is in the torsion
spring. The very fact that you had to ask tells me that you
should NOT touch the torsion spring. They have a lot of energy
stored in them and can seriously hurt you if you don't know what
If the problem is not in the door, perhaps running the operator
through its cycle without the door attached will let you diagnose

My mother's door was recently making a noise, and
I stopped it by rubbing a candle along the wood
panel edges when I had the door partially raised
to expose the surfaces. Some sag seems to have made
the surfaces to rub a bit.
It was also my cue to snug some of the hinges, which were
allowing the sag of one panel relative to the next.

The unit was put in before we moved in, as a condition of our house

If the door is disconnected from the opener and works smoothly up and down
then that means the opener has a problem. Even small cheap openers can open
big doors. Try operating the opener disconnected from the door and report
The opener appears to be fine by itself as well.
Just to recap, the door can be opened and closed manually without any
The opener can run without apparent issue by itself.
When the door is connected to the opener, the opening of the door is
fine but when the door is lowered, appears to bind about half way. The
motor seems to be pushing, but there is a loud rattle and eventually it
I can't see it being a torsion spring issue as the spring is what helps the
door go up (by taking up most of the weight) & you report the door goes up
So - try the other poster's suggestion of checking out the opener on its own
& the door on its own to see which is causing the problem.
If it is the door -
Look at each hinge on the door for any signs of cracking & try to spin each
roller to ensure they are moving freely. Try a quick shot of lubricant on
Your door likely has a couple of steel cables on either side of the door -
attached to the bottom of the lowest panel. These run up to take up rollers
on the torsion bar. Check that the cables are not frayed and that they are
winding properly on the rollers.
The door could be rubbing on the frame as it goes down.
...And finally - I agree with the other poster if all else fails to call out
a door mechanic. They do this for a living & can get you going in no time.
But many openers have enough pull to open the door w/ only one of the
two springs but that wouldn't be enough to balance it w/o the
opener....I'm just suggesting OP make sure before just yankin' on the
By the way, watch out for rip off garage door repair guys. The ones with
full page ads in the yellow pages promising a $29 repair call. They may be
crooks. One guy said all parts had to be replaced and wanted $600. For
that I could have gotten a new door. I thru him out.
Wayne Dalton stores around me fix all brands and are reliable. They also
make great doors and openers.
There are a slew of items that can be causing you this grief.
I doubt you have a broken spring. The roller being missing and the
grinding noise is an indication that the door may not be level or the tracks
not plumb. First visually inspect *everything* on your door from loose
hinges to rollers with missing wheels to something leaning against the
opening. Check to see if the cables are wound properly around the drums.
Make sure the drums are set in the same position. It's possible that one of
the drums has *slipped* on the shaft. Look at the drums to see if one of
them is rubbing on the track or if an end bearing is to blame.
