Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

Garage Door Opener

My garage door's sensor was triggered by a cardboard box, and now I can't make the door open with the wall trigger or with the remote door opener. Is there a way to reset it? I can't find a reset button unless it's on the top and I can't see up there. I've tried unplugging the unit for a few minutes to see if it would reset and it didn't. It was an extra line of defense against intruders, because you couldn't open the door by hand, you had to use the wall trigger or the remote. Now it rolls way too easily. I just bought this house and it would be great if I could find a manual online that I could download.

Using the wall pad and holding it down bypasses the door sensors. The door should still open, make sure that there is power to the unit and make sure that your sensors are lit (Orange/Green) and pointed correctly. If all else fails, unplug the unit and leave it unplugged for at least an hour.

Why does my garage door close and then go back up?


This will happen if the IR sensor are sensing an obstruction while the door is closing OR if the IR sensors are defective. As a first option, check to see if any object is stuck to the door (possibly low down) that is triggering the IR sensor.

It sounds like a problem with the infrared safety beams, either they are not working, are misaligned (someone might have kicked/bumped into one), or I even had one that didn't work because there was too many cobwebs/dust covering one of the lenses.

Sounds like someone else in your neighborhood has the same garage door opener and it's on the same radio frequency as yours. And yours may be opening theirs. Your frequency can be changed, but you'll have consult your Owners Manual on how to do it or contact Sears.

If someone in your family carries the remote garage opener in the pocket or purse, it can be accidentally triggered. I say this, because my mother-in-law used to do it all the time.

My Chamberlain garage door opener works fine except when the sun is shining, then it acts like something is blocking the sensor. How can I make the door opener work in the daytime?


There are a couple easy solutions for this. You can try switching the sensors side to side or use the cardboard tube that comes inside toilet tissue to shade the lens.
