Why Does My Garage Door Stop and Go Back Up? 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.
It's very important not to attempt major garage door repairs on your own, as they can lead to property damage, injuries, or even death.
While basic plastic rollers usually only last a couple of years, steel rollers and nylon rollers can last a long time. The life of your rollers also depends on the average number of daily cycles your garage door goes through, or how many times it opens and closes on a daily basis. May 16, 2022
