I have a double garage door which I believe is called a retractory type. E
ssentially it has 2 coiled springs (one each side) and 2 runners at ceiling
height for the door to run on.
I am about to fit an electric door opener and looking around for advice it
seems I need to firstly ensure the door works properlly - sounds sensible t
o me :)
Anyway...... I *think*
mine needs adjusting and was hoping you could help
When I open the door, I have to give it a tug (or push the top in) and it w
ill lift itself to around 3ft off the floor and stop. I then need to lift
it myself and push it into the fully open position. If not in this positio
n, it drops itself to around 5ft off the floor.
When I close the door, I give it a pull and generally it gets down to the 3
ft mark itself. I then push it into position with the last inch or so requ
iring the use of my foot :).... Just before the foot action is deployed, on
e side of the door seems to be in position whilst the other needs to go in
about an inch....
Forgetting the foot bit for a second, is this the standard behaviour for su
ch a door? The advice re: the opener suggested that a properly balanced doo
r should stay in whatever position you put it in....
Any idea what is causing the door to be out of line when closing (it is fit
ted squarely into the frame)... Could the springs be out of synch? Can the
y be adjusted?
Thanks in advance for your advice....
