Locate the safety sensors, which are typically small, black boxes mounted on the garage door tracks near the floor. These sensors work in pairs, with one transmitting a beam and the other receiving it. Observe the indicator lights on both sensors. One sensor (transmitter) should display a solid red light, and the other (receiver) should display a solid green light. If any light is flashing or off, it indicates a problem, most commonly a misalignment or obstruction.
