Our Genie garage door opener has no manual and the model number is covered with the mounting brackets. Our auto reverse safety beam is out of alignment and we can't close the door without holding the house closer button until it completely closes. We have the following numbers 33 2 4 W which relate to the year month day of the product. Does this help tell us what model of Genie intellicode we have. The case is a shade of red with white cover for the light bulbs. Thank you in advance for you assistance. Mike
