The Sears/Craftsman openers are Liftmaster. I have one and it does not
have electric eyes. There is an adjustment for downward force
sensitivity. You adjust it by closing the door on a roll of paper
towel used to represent the family cat being squashed.

Turn the down force adjustment screw 1/4 turn clockwise. I had this already
this past week on 2 of my 3 doors, and that did the trick for both.

Either the limit switch is out of adjustment or the current sense is
set too low or both.
