Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
It opens fine, but does not close all the way down with remote. It comes down half way and then goes back up again - we have to keep the button pushed to make the door go all the way down. The two sensor lights seem to be working fine (none of them is red; one of them is green and the other yellowish).
Any help; idea to fix it?
You have a door sensor problem. Make sure the sensors are pointed at one another and the small light on each one is lit and not blinking. Also check the wiring.

Make sure neither light on the sensors is flickering. Tweak them a bit to make sure they are aligned properly.

Testimonial: "Thank you for the quick response. The lights are not flickering. We can now open with both remotes but cannot close the door with them. We have to us the wall unit. "
If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

Make sure the brackets for the sensors are tight and the small light on the sensors is not blinking ever so slightly. You also might try shading the sensor so that the sun is not shining directly into the lens.
