I have a LiftMaster garage door opener.When the door closes it is not completely closed on the right side. It has about a 1/4" gap at the bottom. It starts closing evenly but when it is about 2 feet from the floor it cocks a little to the left which appears to cause the gap. Is there an adjustment for this?

It sounds like the sensor on the top section of the door may be mounted upside down. If you can, remount it right side up, and see if that corrects if the problem. If not, contact me directly.

The opener is closing too far. On the side of the opener, you should see 2 white knobs, recessed into the side. Using a flat blade screw driver, adjust the close knob (closest to the door side of the opener), anti-clockwise until the door will close gently on the floor.

The opener should have an antenna wire hanging out of it. Did someone/something hang on it?

SOUNDS LIKE YOU MAY NEED A SERVICE TECH.

IF THE CABLES ARE NOT RUNNING PROPERLY ON THE DRUMS IT WILL CAUSE THE PROBLEM YOU DESCRIBE. OR THE DOOR COULD BE CATCHING ON SOMETHING (DOOR JAB, TRIM ETC.) AS IT CLOSES.

I DON'T RECOMEND TRYING TO ADJUST THIS YOUSELF A PRO CAN DO IT IN ABOUT 10 MIN. IF YOU START MAKING ADJUSTMENT WOITHOUT KNOWING EXACTLY WHAT YOU ARE DOING YOU WILL PROBABLY JUST MAKE IT WORSE.

THE SERVICE CALL SHOULD BE $ 50.00 - $100.00

ALSO DON'T CALL A HANDYMAN ETC. ONLY A QUALIFIED DOOR REPAIR TECH.

HOPE THIS HELPS

Check the sensors in the doorway. Sounds like they may be misaligned. They need to be pointing at one another to work properly.

See if the trolley is jammed against the bolt just in front of the motor unit. If so remove the bolt and then run the opener until the door is closed. While the door is closed locate the 'up limit' control which is on the side of the motor unit. Turn this control 2 complete turns in the opposite direction of the arrow printed on the cover. Remember to replace the bolt.

On the side of the motor unit you will find the 'down limit control'. Using a small screwdriver turn this control in the same direction as the arrow printed on the cover. Some tweaking may be necessary to get it just right.

check the safety photocells is theres not obstacle between then, check both photecells leds are on.. otherwise no need to replace them

IF U HAVE TWO EYE,SENSORS ON EACH SIDE OF THE DOOR SEE IF SOMETHING IS BLOCKING THE EYES OR SOETHING IS COVERING THEM, OR THEY ARE OUT OF ALIGNMENT, ONE SHOULD SHOW GREEN, AND ONE RED EYE, GOOD LOCK

Hello,

There should be 2 sensors on the bottom of your door on the inside, 1 on the right side and 1 on the left side.
These sensors serve 1 purpose to send a beam or reflection to each other.
If something is blocking this reflection or is in front of the sensor the door will always come back up.
It is a safety feature so nothing or no one gets hurt when the door is closing!
