You have a problem with the safety sensor. Realign the sensor, check to See if they are mount in same height, move the eye it self so it point straight with the door and in level both side.
Then check the wires @ the sensor(sometimes I see animals had chew on the wires) Check any splice @ the wall to the pre wiring and @ the motor-head. Make sure the wires is correctly inset to the connector on the motor-head.
