My garage door only goes down part way and then goes back up.?

I thought maybe the sensor lights were not lined up correctly. But even when I unlatch the door from the carriage the carriage only goes a little way and the comes back and the overhead light starts blinking. What else can I check. It’s been acting up for a couple of weeks now.

    On the back of the power unit is an adjusting screw that controls how far the door will go down. A small screwdriver is all that is needed.

    The only reason the opener will reverse and the lights will flash is that the safety beams are misaligned.

    Look for something tripping the ‘safety edge’.

    It’s the safety eyes. That’s the only thing that it could be if it goes part way down and the lights blink. Move one of your safety sensors up or down until the light goes completely out, and then line it back up so that the light comes back on solid. If it still doesn’t work you may need new sensors (could have been hit by lightning, etc.)
