Garage opener has four adjustable controls.

1. Position stop switches, two of them. One stops the door closing as it reaches the floor, another stops its opening as it approaches the opener.

2. Opening and closing force 

3. Door pull back when it hits obstacles.

he might need to check the pull back control sensitivity
