Hi there happy to help.
does the door reverse and go back up?
do you have a button in the garage for the door separate from the remotes?
What happens when you hold this down?
let me know,
I believe you have a problem with your alignment sensors here.
They are either loose and coming out of alignment or out of alignment all together.
You should have a solid LED lit on each sensor. Make sure they are aligned and secure and nyou should be back in business.

Hi, Welcome to JustAnswer.com, I am glad you are here! My name is Eric & I will endeavor to answer your question.
When the invisible beam path (safety sensor) is obstructed while the door is closing or if they are misaligned or if a safety sensor is malfunctioning or if there is a break in the wiring, the door will reverse. If the door is not open, it will not close. The opener light will blink 10 times. (Could you have miscounted the blinks? There is no notation in the troubleshooting manual for a light blinking 9 times).
It sounds to me as though the safety sensors are just barely aligned and that the vibration of the closing door is jiggling them just enough to cause misalignment. Try realigning them and or tighten the bolts that hold them in place.
Do you have a copy of your owners manual?
In the event that you do not, Here is a link to a copy of the Liftmaster Professional Security + model 3110 - 1/3 HP manual. Even if your model number is not exactly the same, the procedures described on page 11 to align the safety sensors are the same.
Please refer to page 11 for alignment instructions.
