The sensor eye - or more likely, the other end, the sensor light - probably got knocked out of alignment. The eye should have an LED on it - possibly one that glows green when it's ready to close or red when it's obstructed or out of alignment. Try adjusting the light until the LED on the receiver glows green.

is bulb on motor flashing 10 times. then you have electric eye problem. otherwise, sounds like you need to increase down force a hair. adjustement is on logic board, right knob.

Most likely your door sensors have been bumped and are not aligned properly. Make sure they are pointed at one another and the small light on each one is lit and not blinking.

You need to check the adjustment for the travel of the door ... All automatic closers have a built in safety mechanism that prevents children, pets and even yourself from being crushed by the door ... so if the travel is set to low the door will hit the ground too hard and safety mechanism will activate opening the door again! Look at you documentation for how to adjust this for your particular model :)
