LM5580 - Door Opens Fully then Drops about 6 inches
#2
Hi,

After reading through your issue, i would say it's to do with the curved arm. I'm quite suprised you managed to get it installed in the first place. If you could forward some images of the install and i may be able to point you in the right direction.

Can you confirm if the garage door is balanced? When disconnected from the motor, does the door stay in the halfway posistion?
Kindest Regards,

Sav
