Check the door springs, then remove the cover and take a look at the drive gear. It is a white nylon gear just in front of the motor. May be stripped.

Hi my home have a lift master garage opner this mornig when i try to open but door open only 1 feet not full i try soooo many time but same i chek sensor but same thige


You need to take a look at the door springs to see if one of them is broken. Also remove the cover from the motor unit and check the drive gear. It is a white nylon gear and is just in front of the motor. It may be stripped. It will be obvious if it is.

Nothing wrong with the sensors and they only work when the door is closing anyway. Sounds like you may have a broken door spring or a bad drive gear. The drive gear is white nylon and is in front of the motor. It will be obvious if it is going bad.

Check your door springs. Usually just over the door and can be seen when the door is closed. A broken spring is the most common cause of this problem.

I can get the door opner to porgram? on a chamberlain md 1245r


On the rear of the motor unit just to the left of all those white wires you will find the smart/learn button. Press and hold the button on your remote and then press and immediately release the smart/learn button. Do this for each of your remotes.

Garrage door opener ability to close the garrage door


HOLDING DOWN THE WALL BUTTON OVERRIDES THE SAFETY EYES.
WHEN HOLDING IT DOWN MAKES THE DOOR CLOSE PROPERLY THE PROBLEM IS IN THE SAFETY EYES.

ARE BOTH LEDS ON? - CHECK FOR A LOOSE OR BROKEN WIRE.
ARE THE EYES WIRED CORRECTLY?
ARE THEY AIMED AT EACH OTHER?
