一般來說，車庫門關不了的原因有以下幾種：

Generally speaking, there are several reasons why a garage door cannot be closed:

1、門軌道故障：門軌道不平整，或者有雜物阻擋導致門無法完全關閉。

1. Door track failure: The door track is uneven or obstructed by debris, which prevents the door from fully closing.

2、門板接觸點故障：門板上的接觸點可能已經磨損或損壞，導致門無法正常關閉。

2. Door panel contact point failure: The contact points on the door panel may have been worn or damaged, causing the door to fail to close properly.

3、門板五金配件故障：比如是門板上的合頁或者其他配件已經磨損或損壞，導致門無法正常關閉。

3. Door panel hardware accessories malfunction: For example, the hinge or other accessories on the door panel have been worn or damaged, causing the door to fail to close normally.

4、電機故障：車庫門電機可能出現故障，比如是行程故障、紅外保護功能故障等，導致門無法正常關閉。如果您遇到了這些情況，建議聯系的維修人員進行檢查和維修。

4. Motor failure: The garage door motor may malfunction, such as travel failure, infrared protection function failure, etc., causing the door to not close properly. If you encounter these situations, it is recommended to contact professional maintenance personnel for inspection and repair.

如果濟南車庫門在關閉過程中距離地面還有一定的距離就會自動反彈，原因可能是：

If the Jinan garage door is still a certain distance from the ground during the closing process, it will automatically rebound, possibly due to:

1、扭簧系統故障：扭簧力度不夠，也叫做扭簧乏力，導致門無法關閉或自動反彈，這時在電機上調節行程也會失敗。

1. Torsion spring system malfunction: Insufficient force of the torsion spring, also known as lack of force of the torsion spring, causing the door to fail to close or automatically rebound. At this time, adjusting the stroke on the motor will also fail.

2、限位器設置不當：限位器設置不當可能導致車庫門無法關閉或自動反彈。

2. Improper setting of the limiter: Improper setting of the limiter may cause the garage door to fail to close or automatically rebound.

3、紅外線傳感器故障：傳感器可能出現故障，主要是障礙物遮擋或灰塵掩蓋、感應器錯位等，導致車庫門無法正常關閉或自動反彈。

3. Infrared sensor failure: The sensor may have malfunctioned, mainly due to obstacles blocking or dust covering, sensor misalignment, etc., resulting in the garage door not being able to close normally or automatically rebound.

車庫門關不到底，來不及等到工作人員上門，自行檢修解決方法如下：

The garage door cannot be fully closed and there is no time to wait for the staff to come. The solution for self maintenance is as follows:

1、清理門底的障礙物，以及清潔紅外保護傳感器。

1. Clean the obstacles at the bottom of the door and clean the infrared protection sensor.

2、檢查門體彈簧是否失去了彈力，如果需要更換彈簧，應該找人員來更換。

2. Check if the door spring has lost its elasticity. If the spring needs to be replaced, professional personnel should be sought to replace it.

3、檢查車庫門的電機或鏈條盒是否正常，如果是電機空轉門不動，則可能是鏈條盒里的離合器松開了，只需要反向合上即可，如果出現其他故障需要維修或更換。門體的軌道是否損壞，如果需要修復軌道，應該找人員進行維修。更多相關事項就來我們網站http://www.llswdz.com咨詢！

3. Check if the motor or chain box of the garage door is working properly. If the motor is idle and the door does not move, it may be due to the clutch inside the chain box being released. Just reverse the closing process. If other faults occur, repair or replace them. Is the track of the door damaged? If it needs to be repaired, professional personnel should be sought for repair.
