My garage roller door will open but not close what is wrong?


Assuming you mean your home sectional door, not roller door. A roller door is what commercial companies use on docks or storage buildings. Also assuming you mean that your motor unit (the opener) won't close it, not that you can't pull it down manually. With all of those assumptions, I would say either your sensors are misaligned or blocked, or your force needs adjusting, or your springs need adjusting. If you give more details on your questions, you are likely to get more specific responses.

I have a 6 year old craftsman 1/2 HP model139.53985D garage door opener. Sometimes it open/closes fine - other times it opens or closes 6 inches at a time and stops. Springs are fine, worm gear is fine -...


Generally when the door is closing any problem will cause the door to reverse to the open position and stop. This is designed into it. You say your opener just stops when going up or down. This makes me think there is a bad connection somewhere and you are simply losing power. If this is so you should notice that all the small lights that are normally on go out. If this only occurs when the door is going up you may have a bad RPM sensor board. This is a small printed circuit board just in front of the motor.

My door stops while going up or down. i have to push it a few times to open or shut the door. the sensors are aligned.


Unhook the door from the opener and see if it is binding some where. If the opener has trouble, as in harder to move the door, it will stop or reverse direction.
Try WD40 if this is problem. And while you have the can in your hands, spray WD40 on all the rollers, and on the track and on the springs, and if it's a chain drive, on the chain as well. It will make the opener work easier and the door wil sound quiter.

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.

On the back of the motor unit you will find the down force control. You may have to remove a light lens depending on your model. Increase this a 1/4 turn and try.
