Garage Doors/Liftmaster garage door opener problem


Lift master garage door opener goes down 1 foot and goes back up again... both sensors are facing each other, one has a green light, one a yellow... how can we get the door to go down all the way?

Hi Maggie,

Do the lite bulbs in the liftmaster flash 10 times when it goes back up? If they do, you are still haveing safety censor issues. Many times the green lite will blink so quick you have to get on your knees and stare at it. If the lite bulbs do not flash, go the back of the opener where the wires from the pushbutton come in and there are 2 turn screws. One has an arrow pointing down and one up. Turn the down about 10 minutes on a clockface and try the door.

Good luck,

Yours in doors ,

I will not answer questions about garage door openers 20 years old or older as they are unsafe, PURCHASE A NEW ONE. How many cell phones have you owned in 20 years? I have 40 years in the garage door industry and have seen almost everything. I sat on the Wayne/Dalton dealers board in 1986,1987,and 1988. I am on the IDEA board of directors ( and am accredited by same. I will, to the best of my ability answer your questions on doors or openers. I will not deal with shinbuster type doors. Replace it if you have one! If your question is about stretch type springs, call an IDEA accredited dealer and have torsion springs installed.
