My garage door opener doesnt close all the way.

The dial is the force adjustment. if it ever does it again and the light on the opener isn't blinking, its a bad rpm board

SOUNDS LIKE SOMEONE MAY HAVE PRESSED THE LOCK / VACATIONS SWITCH ON YOUR WALL CONTROL. IF STILL NOT WORKING AND THE LED IN THE WALL SWITCH IS NOT FLASHING TRY AGAIN TO PROGRAM YOUR REMOTES.

GOOD LUCK

disconnect motor, check the door is operating smooth and correct. check springs. check downward pressure setting

It could be the garage door motor that is acting up. Try closing it with the button in the garage. If that's not the case, you may need a different garage door opener.

Check your door sensors.

Door sensors have nothing to do with door opening. Only closing. It sounds like you have a bad gear in the motor unit. Remove the cover and it will be obvious if the gear is bad.

You may have a relay faulty or the wiring is connected wrong.

Your door sensors are either bad or need simply to be aligned. They must be pointed at one another to work properly. Each of them has a small light that will be lit when they are pointed correctly.

It sounds like you have the lock enguaged. When it is flashing it locks out all remote access. Hold the lock button for 3 seconds. The green light should go solid. On the issue of closing, it is most likely a safety eye issue. Hold down the wall button. If it closes it is the safety eyes. Holding the button overrides the safety eyes. Make sure that thelight on both eyes are both lit.

There must be something blocking or making it difficult to move, check the belts and lubricate the moving rollers.
