Garage door gets stuck half way up,if i help it, door will go up. Door gos down no problem. Do you have the same question? Does the door operate smoothly when disconnected from the opener? If so it is a problem with the opener mechanics. When was the last time it was lubed properly? If it's an older motor it may be getting tired. Most have an adjustment screw on them to adjust the force at which the door will open. Some have separate adjustments for opening and closing while some are adjusted together. You don't want it to have too much force as it won't sense a person or object giving resistance until it has applied harmful pressure. If you're unclear on how to adjust this safely I suggest you look on Angie's list for a local garage door repair company. It should be a small charge for them to adjust the door and make sure everything is lubed properly. Answered 5 years ago by Todd's Home Services You are due for a Garage door service from a reputable company.your Garage door opener has what are called force settings and they are designed to react to or be sensitive to the door making contact with an object while it is closing or to drag or something catching on the door while it is opening.
This only works properly when the door is balanced and when the settings are adjusted to a balanced door. Your door is no longer balanced this is common and gets to this point about every two to three years as the spring/s gets weaker the door will become heavier to open, your open force setting is reacting to this like it is supposed to and is your warning that the door is in need of service and adjustment. Answered 4 years ago by Garage Door GuruThe limit switch is located on the garage door opener housing. The garage door opener limit switch tells the motor that lifts and lowers the garage door when to stop running. Incorrectly set limit switches may prevent your garage door from closing completely or opening all the way. They can also cause the opener to reverse or pull back up when you attempt to close it, which can seem like a malfunction or that someone else is using a garage door opener remote that is on the same frequency as yours. This is actually caused by a safety mechanism meant to protect people from being hit and having the door close on them.
Resetting the limit switch will stop your garage door from behaving erratically. Open the garage door and watch it closely as it opens. When the garage door opens about halfway, or 5 feet, from the ground and stops, the up limit switch needs to be adjusted. Measure the height where the door stops while it is being opened. The measurement is used to reset the up limit switch on your garage door opener. Close the garage door with the opener and watch it closely as it closes. If the garage door does not close completely, or begins to close and then opens back up again, the down limit switch needs to be adjusted. Measure the distance of the gap from the bottom of the garage door to the driveway or floor if the garage door will not close completely. The measurement will be used to reset the down limit switch. Set the step ladder under the garage door opener in your garage and use it to access the up and down limit switch adjustment screws located on the side of the garage door opener motor housing.
Turn the up limit switch screw clockwise by one turn for every 3 inches that you need the garage door to raise up with a flat blade screwdriver. This may move the chain trolley of the garage door opener. If it does, leave a 2-inch to 4-inch distance between the cover protection bolt and the trolley. It's the part of the door mechanism that moves the chain that opens and closes the door. Turn the down limit switch screw counterclockwise one turn per every 3 inches of the garage door gap -- the distance between the bottom of the garage door and the driveway when it does not close all the way -- with a flat blade screwdriver. Turn the down limit switch screw clockwise one turn with a flat blade screwdriver if the garage door closes and then begins to open back up. The garage door will automatically go in reverse whenever it hits an obstruction, such as the driveway or ground. In this case, the garage door opener detects that it is coming into contact with the driveway or the ground and immediately switches into reverse and raises back up as a safety mechanism.
Try to close the garage door. If it still automatically begins to reverse or open back up, turn the down limit switch screw clockwise one turn and test it again. Continue turning the down screw clockwise by one turn and testing it until it no longer automatically opens back up when you close it.

If your garage door keeps sticking at the halfway point, resolve the problem as promptly as possible because ignoring it will exacerbate the problem. Open the garage door all the way and wipe down the tracks with a dampened cloth. If dirt and debris has gotten trapped in the track, it will stall the garage door as it descends. Climb up on a stepladder and find the force knob on the back of the garage door opener’s motor casing.
Turn up the force setting slightly and see whether that causes the door to stop sticking at the mid-point. A force adjustment is often necessary if the weather turns and the materials used in the door swell or shrink. Check the metal rails to ensure that they are not bent. If the rails are bent slightly, pull them back to true using a pair of locking pliers. If the rails are bent significantly, you might need to replace them.

Garage doors are heavy, and to prevent injuries manufacturers of automatic openers include safety sensors to stop the door when someone is in the way.
When the door won't go down automatically, these sensors are often at fault. If the door does go down but stops before hitting the floor, you may need to adjust the opener itself. It's important to keep the floor around the door clear, because small objects impede its movement. Safety Sensors If the door goes up, but you can't make it go down, you probably need to adjust the sensors. There is one on each side of the door; they both have lights, and both lights should be on. If one of them is off or blinking, it means the invisible beam that tells the opener that the way is clear for the door to close isn't aligned. You can usually realign it by loosening a knob or simply pushing against the metal bracket holding it. When the light comes back on and stays on, the door opener should operate normally. Frequent Sensor Misalignments If you're in the habit of leaving the garage door open, a variety of things, including dust, water and even pollen, can blow in with the wind and settle on the sensors.
Cleaning the sensor lenses periodically prevents this from becoming a problem. Another issue that can arise-- especially if your garage door is heavy -- is that the vibrations the door makes on the tracks throws off the sensors. If so, each track may need a brace to stop the vibrations; it won't hurt to tighten the sensor adjustment screws a little more, as well. Door Travel Adjustment When closed, the weatherstripping on the bottom edge of the door should be in contact with the ground. If your door doesn't come down that far, you can adjust the automatic opener until it does. Inside the casing of the opener you'll find two adjustment knobs. One controls how far the door closes, and one controls how far it opens. Adjust this knob to lower the door to the floor, but don't adjust it too far, or the door will push against the the top track. If it does, it will bow the track, which can cause excessive wear on the opener. Worn Gear, Binding Tracks If you hear a grinding sound when you operate the controls but the door doesn't move, the gear inside the opener is worn out.
