If this door opener is getting old(over 10 Years) buy a new one. They very often fail and cost of repair exceeds the cost of replacement.

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!

Check the down limit:
 If the light bulb(s) on your operator are on the front and/or back, the limit adjustment screw is on the left side of the operator (looking from the back of the operator and facing  the garage door).. If the lights are on the sides of the operator then the limit adjustment screw is on the left side (looking from the back of the operator and facing  the garage door)

SOURCE: garage door squeak when closing

I had a similar problem and tried simlar fixes. Spraying the chain, the rollers, the track with silicon based lubricant did not good for my problem. My wife then listened carefully from where the squeak was coming. It was coming from the hinged in the actual door, the hinge like parts that allow the door to roll up. After we sprayed all of them, the sound just went back to the normal electrical / mechanical sound of the door opening and closing. I am sure our neighbors are happy too after 6 months of (very) early openings. Hope this helps.

My Essati electric garage roller door will not open further than 1/2 way following crashing into an object. It will close but does not know when to stop. How do I reset the door ?

Pull the red release handle to disengage the opener. Open the door with the remote. The door shouldn't move but the opener will operate. When it stops, physically open the garage door and push it all the way up. Now re-engage the release handle. GJiggle the door slightly to make sure the handle has engaged the opener. Now close the door. It should operate normally now.

Liftmaster GDO goes up 1/2 way and stops,springs are fine.

The Liftmaster openers have 4 movement switches, a )opening and b) closing limit and c) opening and d) closing force. First check the door for smooth operation by opening the door by hand (disconnect from the opener with the release cord). Any binding should be felt this way. It is possible for a binding hinge, roller or torsion springs to add too much drag and cause the force switch to shut off the motor. Hinges, roller shafts and torsion springs should be lubricated at least annually with a non oily spray (silicone or teflon spray). Not WD-40 or 3-in-1! A light band of lube should be applied to the torsion spring coils. If the door can be operated smoothly by hand, then adjust the closing force switch 1/4 turn at a time. This is a safety device do not use it to overcome another problem!

The down adjustment broke off

Check the micro switch that will be activated when the door reaches the closed position. It might need to be readjusted as it is supposed to be activated just as the door reaches the fully closed position to stop the further movement of the door. If it does not get activated at that point the door will try to open further but sence an "obstruction" and start opening again as a buildt in safety measure for protection against possible injury or damage to property.

Genie trac drive

Over time, grime gets into the tracks, lubricant gums up in the rollers, and more pressure is needed.

On the ceiling mounted motor unit, there should be a pair of adjustment screws.
On my LiftMaster, they're labeled "OPEN FORCE" and "CLOSE FORCE".
These will increase the force exerted in the respective direction.
Make sure you are not adjusting the two screws that control the travel limit.
Adjust a LITTLE (like 1/8 to 1/16th of a turn at a time) and test before adjusting further.

Garage door not opening properly.

Check the springs on your garage door. If one is broken, the opener will not have enough power to raise up and it will stop like that.Or the up and down limit settings have gone off or bad.
