I have a liftmaster pro9000 this morning the door will only open halfway if I press the remote it just closes again please can you help me

It suggests there is something cause an issue on the runners.

Check on the inside of the door to see if you can see any object preventing the door going along the runner.

Secondly use the manual release to see if the door is binding or moving freely as it may just be the door needs serving as its binding, as the liftmaster will only operate up to a certain force.

Hi Stan if you open it manually up and down do you feel alot of friction, as to me it sounds like it could be the door whats getting stiff, this can be overcome by getting the lifemaster to use more force, but its better to check the door as you could end up making the issue worse over time.

Thanks James
I did as you suggested and oiled the screw and it seem to work fine.

Great, do come back to me if the issue continues, at which point you may need to use grease instead of oil.
