    the video’s.

    Our door was going up 2-3′ and stopping, The chain was hanging low, the
    video made the chain adjustement a breeze. The door was still doing the
    same thing. The over head track j(ust below the chain) had a lot of dirt. I
    sprayed carb cleaner on it and wiped it down. There is the mechanism that
    moves along the track below the chain, I used bicycle chain lube on it and
    the track below the chain, that did the trick. If the track gets built up
    on it it causes friction.

    Nice work you guys that helps me a lot. However, I did fix the chain but
    the door open half way and then stop. It closed okay but problem with
    opining! Any idea?

    Safety Warning: The video doesn’t mention to unplug the unit before
    performing this maintenance. If you do not do so, you run the risk of the
    opener engaging and hurting yourself – even with “vacation mode” set.
    Other: 1) The trolley is to be disengaged while adjusting the tension
    (Liftmaster website example). 2) The slack between the chain and the rail
    should be 1/2 inch at the midpoint when opened (easy using a folding ruler
    with the last section at 90 degrees)

    It new and the other one working perfectly!

    Thanks for your video. My chain was coming loose, tightened it up just like
    the video demo, but garage door wouldn’t open. I noticed that I couldn’t
    even manually lift the door. Spring that goes across the top is broken,
    thus the strain of opening was stretching the chain. Getting spring
    replaced for $250. Thanks.
