Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+
The wall unit is the only way I can get it to close all of the way. When using my car remote unit it goes down and when it gets about 6" from the ground it reverses back up.
IF THE DOOR CLOSES ALL THE WAY WHEN HOLDING DOWN THE WALL BUTTON AND REVERSES 6" FROM THE FLOOR WHEN NOT HOLDING THE BUTTON.
I WOULD GUESS THAT THE SAFETY EYES ARE MOUNTED ON THE TRACK.
WHEN THE DOOR CLOSES THE TRACK AT THE BOTTOM IS TOO TIGHT CAUSING IT TO FLEX AS THE DOOR GETS NEAR THE BOTTOM. WHEN THE TRACK FLEXES THE EYES ARE POINTING FURTHER AWAY FROM THE DOOR AND EVENTUALLY THEY ARE TOO FAR OUT OF ALINMENT AND THE LED WILL GO OFF - THE DOOR GOES BACK UP.
SOLUTION: YOU CAN USE THE CLAW END OF A HAMMER TO TAP THE TRACK OUT A LITTLE WIDER - TAP NEXT TO THE WALL ON THE BRACKET THAT HOLDS THE TRACK TO THE WALL. MOVE THEM ABOUT 1/4" EACH SIDE.
YOU CAN MOUNT THE BRACKETS TO THE WALL OR THE FLOOR.
THIS SHOULD SOLVE IT
HAVE A GREAT DAY

Check that the photo beam are aligned... or increase the down force a little until it can be close.. try to close the garage door manually to see is there isnt any obstacle
