Question about Building Materials
See if holding down the wall button, the door will close. if it will, then it is a sensor issue.

You have a sensor circuit that prevents the door from closing. One sensor sends a beam of light across the floor by the door, the other sensor picks up the beam. If beam is interrupted, say by a car, the circuit prevents the door from closing. And if the sensors are not properly aimed it is as if you have an obstruction and the door will start to go down and then reverse it self.
Circuit only works for closing and not opening the door.
Adjust and hook up the sensors as per the intructions.
