What Genie says to do
This is a safety-sensor code. The sensors stop the door closing on a person, a pet or a car. semiatic repeats only Genie’s own alignment and cleaning steps; nothing here tells you to work around the sensors, and Genie’s wiring checks are on its own page.
- Genie says to make sure the Safe-T-Beam lenses are clean and that nothing is blocking the beam.
- Genie says the lenses should be mounted 5 to 6 inches from the floor on either side of the door opening, aligned facing one another.
Genie’s pages also point to loose wires and to the owner’s manual for further causes.
Genie’s safety line: “If you suspect a problem with the garage door hardware or springs, contact an authorized Genie dealer or a trained door technician.”
No repair advice of our own. The steps above are only Genie’s, as its page states them; semiatic gives no repair instructions of its own. For anything beyond them, Genie’s page and a trained door technician are the authority.
