Many homeowners that experience trouble opening or closing their garage doors with electric motors called the operator, are often surprised at some of the reasons the door won't open or close. There often can be multiple explanations for this problem but two really stand out among the rest.
Before you call a repairman or the neighborhood handyman, first go to your garage and face your garage door from the inside. Then look at the bottom left and bottom right areas of the door. You should see a red light on one side and a green light on the other. These are the photoeyes of the garage door. They are part of the saftey system of the door. If one light is blinking then an object is obstructing the laser beam that crosses the opening under the door, or the photoeyes are not aligned. Realigning the photoeyes and cleaning the lenses should correct the problem.
If the door will not close all the way down or raise all the way up, then your operator's limits are off. These "limits" are settings in the operator's circuit board that tell the motor when to stop the door up or down. If this is the case, consult your operator manual, the installing company should have left it with the door, to read on how to re-set the limits.
