> The photo-cells have to be connected for the unit to work properly.
> Swap the two photo-cells, if the same one still fails to light it is

> wire or the unit. The opener should open fine without the photo-cells
> working properly, but you have to hold constant pressure on the wall
> button to get it to close. If it works in both directions in this
> manner the problem is usually either in the photo-cells or the
> photo-cell wiring.
