Question about PC Desktops
I will assume you are talking about a garage door opener. The problem is that either the sensors are misaligned or a wire or wires have become disconnected from one of the sensors, or worst case, the main unit is bad.
Visually check the 2 sensor units at the bottom of the track near the floor of your garage. When they are properly aligned the LEDs will be green on both units. If misaligned (or when something is blocking them) one of the LEDs will be orange. If either of the LEDs is off, the problem is in the wiring or main unit. The wires are marked with black or red stripes and must be connected to the matching screws on the main unit.
