Whenever the weather is cold, my garage door gets stuck when it's opened
about six inches. I have to help it along by pulling it up when it reaches
the six inch point. I have oiled and WD40'd the central track that actually
pulls the garage and although this seems to help once, I'm back to the same
thing again the next day.
Also, it doesn't have to be very cold. If I get up and the temperature is
40 degrees, I'll get the same problem.
Andy ideas on what to do about this or what's causing it?
At my Mother's house, we are having this problem, too.
I oiled and everything. Then I discovered that the tracks are out of
alignment. Measuring diagonally from front to back should be equal
distances, but they are off by about 5". The door stops about 2 feet up in
the cold winter months. It can be opened manually - sometimes - but it's a
Disconnect the opener and open and close it manually. It should stay
fully open, fully closed and it should be balanced about half way up and
move smoothly all the way. My guess is the springs have stretched over the
years and now need adjusting. If you don't have the the installation
manual, get a pro in to take care of it. If you have the manual read it
carefully and pay attention to the warnings.
And I suggest that WD40 should not be seen as a lubricant.
It displaces water, it serves as a penetrant, it loosens stuff,
but it is not a lubricant.
Small amount of lithium grease on the opener track should
I prefer to remind of the Meehan reminder. Disconnect the
opener, raise the door until one of the springs shows a sag.
The other one should be doing the exact same thing. If they
have the same color end, and are identically anchored at their
attachment point, it's time to think about replacing both of
them at the same time. This time with the steel 'keeper' cable.
In the process of raising the door, note any places where it
binds, even a little bit. And when the door is at about hip level,
you should be able to turn loose of it and it should continue
to sit there.
Regarding the 6", see what is 6" above the door. Might be the
start of the radius portion of the track, there's a junction there.
You need to see what the opener 'feels'.
Yea, they call it a lubricant. It is, but it is a very poor lubricant
for most uses. It is more of a solvent. For the use in question it is
worthless as a lubricant, but it does make a good solvent and cleaner.
BTW NEVER NEVER use that stuff in a lock. It will in time just gum up
the works really bad.
After lubing with oil and checking movement disconected from opener and
adjusting if necessary there are up-down force adjustments on the motor
that may neeed adjusting. Disconected from the opener the door should
open and close with equal force
Is it a screw drive opener? If so the wrong grease may have been used
that thickens when it gets cold. If so the screw needs to be flushed
w/ oil & regreased with the proper type. Lubriplate Low Temp is what
is normally recommended.
If it's a chain drive or belt drive the bottom of the rail should be
greased lightly the full length of the rail.
Of course this in addition to making sure the door works properly by
hand as many others has mentioned.
