A garage door that stops and goes back up is usually due to malfunctioning infrared sensors. If there is such an issue, you can see one of the sensor lights blinking. Malfunctioning sensors can be caused by a blockage, dirty eyes, loose wires, or just bad sensors in general.
The best way to determine if your garage door is no longer aligned is by noting unusual operations like unpleasant noises or inconsistent movement. Garage doors can easily become misaligned due to loose, damaged hardware or force that causes the panels to become damaged or dislodged from the track. Dec 1, 2018
