That normally happens when the sensors aren't aligned. Both sensors have led lights on them the yellow/orange one will stay on all the time the green one will go out if it cant see the other sensor. Possibly theres a wire that's broken or the other sensor is really out of alignment. Check every inch of wiring from the sensor to the opener, remove wire nuts if present and check the connections. The wires that are used are small, solid and can break easily. Also see if there's a staple that's too tight, move the wire abit where it's stapled and look for damage.

If the sensor light or receiver gets kicked, it can be knocked out of alignment. If it's not aligned, it will act as though it is blocked -- in other words it will open, but not close.
I fixed my buddy's opener not long ago -- you should have two parts of the sensor, near the floor at the bottom of the door. One is an infrared light, the other is a receiver. The receiver should have a little LED on it. This glows green when it is receiving a clear signal from the other side. If your's is glowing red when you can see that the path is clear, try adjusting the aim of the infrared light. You should be able to gently move the light from side to side until you see the LED on the receiver glow green.

If you have to hold down the button to close the door, you are bypassing the sensors ...
Check the alignment of the sensors. Should see a solid GREEN light

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.

your garage door has saftey sensors at the door
these are photo eyes
in the owners manuel that came with the opener
that has pictures in it which would help
the photo eyes need to be clear of debri and aimed at each other with no obstruction
there are leds on each sensor and when aimes properly they should be light if i remember correctly
if you can not get them to light then you may have to replace the sensors
