View Garage Door Opener Will Not Stay Closed Images. If your garage door opener lights blink 8 times, it means that you have a chamberlain, craftsman or liftmaster opener, and will confirm that it is a sensor issue. You have a train running in your garage?
So it's worth it to take a few seconds to. This is a frustrating situation and one my remote will open the door, but it will not close it. A garage door opener works by using a small, electric motor to lift a rolling door assembly.
I like them so much because they work very well and last a long time.
Liftmaster garage door openers are some of the most popular options we have today. If your garage door won't close then confirm that you have active power to your garage door opener. On the side of the opener, you should see 2 white knobs, recessed into the side. Sometimes, you'll notice that your garage door closes all the way and then immediately goes back up instead of staying in the closed position.
