Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
I can open my garage door with the remote just fine, but it will not close the door. When I try to close it from the button inside the garage I have to hold it down until the door is all the way closed, otherwise it starts to go up again. However, when I want to open the door from inside I can just press the button and it will open without having to hold it down. Would like to know how to fix this problem, is a pain when I leave the garage I have to go park in front of the house, go back in the house and into the garage to hold down the button to close the door. Can you help.
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.

Check your door sensors. Make sure they are pointed at one another and the small light on each one is lit and not flickering ever so slightly. Tweak them a little. If you cannot get both lights to come on you have bad sensors.
