First check the spring to make sure it's not broken. Release the motor latch and then try to open/close the door manually. If it' s pretty easy, you can adjust the motor force and lubricate the rollers. If it's very heavy, your spring is broken and you need a new one.
youtube 上好像是这么说, 不过不是说 一般不推荐在开门的状态下这么做,因为有可 能门滑下去砸地面会损害吗? 应该不是弹簧断了吧? 因为这么前天这种症状,多按几次,后来又有一次 work 了。

For safety, you should test it when door closed. However, to diagnose the problem, you should rule that possibility out first . But it is very difficult to hold the door weight depending on the size/ material of your door. So you can increase the push force on motor to force the door close and then test it. If the spring is good, you should be able to lift the door up or push it down with minimal force. And the door should stay where it is when you release the latch. Spring counterbalances the weight of door. If it's broken, the motor has to work a lot harder to open/close door, which will cause damage to motor. I learned it hard way. Had to repair a broken motor first and later realized the spring needed replacement. :( If the spring is good, you probably just need lubricate the rollers and increase the force on the motor a tiny bit. Good luck.

Thanks. Is there any other way to test the Spring? I feel it is not the spring since the door successfully closed once after the problem appeared. I also remember there was a similar case last year when it was really cold in Winter. We did not do anything last year since it only occurred one day. It worked without any problem for the last 10 months. On the other hand, I do think we should do something for the door since it was already 17-18 years old. 貌似所有的零件都是原来的。 车库门,以及这些部件 的平均寿命是多少? 这些弹簧,之类的零件是不是也差不多寿命快到了?

My house was built in 2003. The motor broke this summer and I got it fixed. Few weeks later the door's having problem again (can only open half way), I adjust the pull force to open it, but then decided to do some research and figure out broken spring is behind the trouble. If you have a single door or your door is relatively light weighted, even if the spring is broken, the motor can still open/close but that's not good for the motor. Check the tracks to make sure they look normal. Then lubricate your roller with some silicon lubricant. I heard people talking not to use WD40 but haven't found time to check. Get a ladder to check your motor, you should be able to find 4 knobs to adjust the forces and positions. Slightly increase the force for closing door and hopefully your door will be closed at some point. Then just test the spring, it's super easy to do. If the spring is broken, your motor will develop problems and you won't be able to open the door during power outage when you need get the car out. That's the whole point.
it months.

At least you know the spring is good. It's better to have some sort of weather seal for bottom of door. In your case, you probably should have a threshold installed on the ground in stead of nailed to the bottom without adjusting/checking interference with the frame weather seal. I'd get a couple of professions to come and check the situation. You may need new weather seal for the frame. If you want to change the door/track/roller etc, when I did mine, for a single car garage door with all the hardware (not including spring/opener) ranges from 500 to 800.
