1. Raise and lower the door and check closely for areas of
sticking and binding. Check for loose hinges, wobbly
rollers, frayed cables and damaged or broken springs.
Contact a qualified garage door service person to make
the necessary adjustments.
2. Lift the door approximately halfway. When released,
the door should stay in that position. If door pulls open
or moves downward, the spring mechanism is not
adjusted properly. Contact a qualified garage door
service person to make the necessary adjustments.
3. When properly installed and adjusted the door will
remain clear of the opening, when allowed to rest at its
natural full open position. If door drifts up or down the
door is not adjusted properly. Contact a qualified
garage door service person to make the necessary
adjustments.
