I have read the instructions and i can get it to open either all the way up or all the way down, not both. I have tried everything I can think to try including moving the adjustment of the chain. By the way, I have a 3/4 horsepower Craftsman Chain drive unit.

Measure the height of you garage door. The "standard" size door is 7 feet high. Out of the box, Craftsman openers can raise a door 7 to 7 1/2 feet. If you have an 8 foot or taller door, you will need the appropriate extension kit for your opener - listed near the end of the manual on the "accessories" page. Using the kit would require you to move the motor unit further back in to the garage, so if you can live with the door not quite opening all the way, you'll save yourself some trouble.

this happened to ours and my husband had to keep adjusting the chain thing until it was dialed in just right. Does it open and close manually? ours would but would only open or close electronically one way and a bit the other but not both. good luck
