Our Garage Door opener Jerks when it opens and closes. Its like the
opener does not make an effort to open easily or slowly, its like it
just dropped the clutch. does not matter if its up and closing or
closed and starting to open !

Are there any openers on the market that stated the movement slowly ?

Thanks

Hi,
Chain drive, belt drive, screw drive? Consult manual, there may be an
adjustment for that.

I have seen many openers jerk when
starting. In my new house, with new
doors and openers it works pretty
smoothly, but they are fairly light weight
fiberglass, 1 car doors and are, as I
said, brand new. One thing to check is
that the door is properly weight
balanced by the springs. The opener should
not have to push a lot of door weight.
With the door disconnected from
the opener, you should be able to open
and close it fairly easily. If not,
the springs may need to be adjusted.
Adjusting springs is not for the
faint of heart and can be REAL
dangerous. It's usually a job left to a
professional door person. All hat said,
a wooden, 2 car
width door in the up position can be
somewhat hard to start as there is
quite a bit of mass to get moving.

disconnect opener the emergency release.

now try the door by hand check for rough spots hangups. door likely
needs lubrication

this door have long springs? they stretched? be sure they have safety
restraint cables!

Sounds like the spring that ties the two ends of the chain together is
weak or loose. There is no clutch. Unless your track is binding the door
it's entire length. A heave drag will make it bounce in both directions.

Its a LiftMaster Chamberlin Professional, Formula II
It uses a belt with teeth.

The system has been up 5 years and has been jerking since the day it
was intalled.
I questioned the builder on it, but he stated that there was nothing
that he could do.

Its not a question of spring tension or lubrication, its just a fact
that the panels of the door have some natural play between them and
when the opener starts to move, its with an abrupt manner. The whole
door (all the panels) bounce back and forth for about a 2 count,
before it settles down and travels the rest of the distance.

One would think that a designer would design the opener to start out
slowly and then get up to speed. Not just close a contact and engage
the motor like dropping a clutch (I know there is no clutch, just
trying to draw a picture).

Any ideas, Thanks

Hi,
Checked belt tension? Or loose sprocket/pulley on thw ahaft?
Ours is screw drive and there is an adjustment for that.
S\Yet, better consult the manual.

Not to be too much of a wisea$$, but my idea is that the builder is right... there's not much that
can be done!

That opener may jerk a little more than others because the belt drive probably has a little more
stretch (= springiness) than the chains or worm drives used in other openers. So one solution would
be to replace the opener with one with a different type of drive, although every opener I've seen
does what you're talking about to some degree.

From a design perspective, having the motor start slowly would be great but would considerably
increase the cost of the unit. Right now it's just got a dirt-cheap motor and a relay to turn the
motor on and off. A variable-speed motor and control circuit would be much more costly.

Try adjusting the UP/Down force. Tweak the adjustment until the
jerking motion stops.

Try some oil on the big spring above the garage door. I had that problem and
lubricating the spring along its length eliminated the jerkiness.

Yes. I had a single garage door replaced in the past month or so and
the installer stated to spray the spring and tracks with "silicone
spray" every few months (friction?)

It may not be the opener at all.

Yes, lube the overhead spring is GOOD. I've got pros that tell me
that!

The Genie "Excelerator" model has a variable speed motor and only
costs $10 or $20 more then similar regular motor models. The Opening
speed is twice as fast as the closing speed. And it self adjusts the
first time it runs (or after there's a power outage) by going very
slow and setting it's own stops at each end. It's the typical genie
screw drive, which I've always gotten outstanding service from. It
also seems to start and stop more gently in general then "regular"
openers.

In my case there was a lot of friction which caused the spring to jump which
corresponded exactly with the jerkiness of the door opening and closing.
