Liftmaster 1/2 hp won't open


Turn the gears again by hand like you did and lower the door a couple feet. Now find the 'up limit' on the side of the motor unit and using a small screwdriver turn this about 3 turns in the opposite direction of the arrow printed on the cover. Now you can go ahead and operate the door.

Garage door opener motor doesn't work.


2 flashes is a safety eye issue, but you problen is most likely that the chain is not sync with the limit setting. Take the bottom off the gear and sprocket assemble and rotate center limit srew until it is in the same position as the trolley.

Garage door opener motor will not open garage door


It sounds like you did a really good job! My Craftsman 1/2 hp gar. dr. opener has a red reset button on it on the l/h side as you are looking at the light/motor from the garage door opening. You have to take the light cover off to be able to see it. My reset button is on the same side as the ground wire. You might check the ground wire while you're there. I really hope that this fixes it for you (and me). I'm quite sure it will as you know your way around the garage door opener already. Good Luck and Let me Know (Please) if it fixed it or not. If I think of anything else, I'll let you know. Have a Good Day!

Garage door opened, won't close


If you can press and hold the wall button and the door will go down, you have a photo eye issue. Check the photo eyes at the bottom of the door.

Can you adjust the down-travel? On mine, it's a white nylon screw, on the left side, inside the light cover. Seems like there were instructions for this adjustment in the instructions for the gear replacement.
