I have found a simple fix to about 95% of the problems for those of us who have trouble closing the garage door due to sunlight or snowflake problems. It sounds crazy --- but take a cardboard liner from a roll of toilet paper -- put that over the light source for the safey beam near the bottom of the garage door... it 'focuses' the light beam and reduces the interference from sunlight or snow. Try it.
Any other ideas??
