SEARS 1/2 hp garage door opener

I closed my garage door and once completely shut, it began to open again. It goes up to about the 3/4 point and stops. My sensors are not loose. When I put my hand over the sensor, the sensor green light goes off on one but the other sensor green light will not go off. What do I need to do to make it function normally again?
