I've had mine act up when the light sensor is bumped. Until I read it
here, I generalized that all GD openers had sensors on them. Learned
something on AHR that day.

Now... GD openers are starting to, at least one company, get away from

Example: (disclaimer I have this brand door but not this opener)

_Exclusive Soft-Touch Reverse TechnologyT_

While Closing:
The door & opener system reverses with just a soft touch- eliminating
the need for troublesome photo eyes

While Opening:
The door & opener system will stop with just a soft touch-
eliminating the appeal for children to ride the door while it opens

Safety - The Garage Opener Digital Intelligence system constantly
monitors the force level necessary to safely open and close your
garage door.

I have two garage doors with sensors. The sensors are mounted atop the
motor, about six inches apart.

Never had a problem with them being out of alignment.- Hide quoted text -
