The reasons and solutions that cannot be used after the electric switching of the phenomenon garage door

\”2\” class = \”Syl-Page-BR\” style>

In the fast -paced modern life, with its convenient and efficient characteristics, the fastening garage door has become the heart of many car owners. It not only saves valuable time, but also provides more safety guarantees for the parking of the vehicle. However, when the phenomenon garage door switches from the electric mode to the manual mode, occasionally the motor cannot work properly, which undoubtedly brings many troubles to the owners.

The principle of electric switching manual details

Clutch device, the key to the flexible switching of electric and manual mode. In the electric mode, the motor drives through the chain or belt,The roller that drives the door moves up and down smoothly along the track, so as to easily open and close the garage door. When you need to switch to the manual mode, the owner only needs to pull the clutch pull rope to separate the clutch device. The transmission connection between the motor and the door is disconnected. At this time, the door can be manually operated.

The cause of the motor that cannot be used normally

clutch device failure

Clutch Rebon: After the manual operation is over, the clutch may fail to accurately return to the initial position of the electric mode, so that the transmission connection between the motor and the door body cannot be effectively established. This situation may be caused by the abolishment or deformation of the clutch rope by the foreign body and the internal parts of the clutch device due to long -term use.

Clutch device Damage: Frequent switching mode, or after a long period of use, key components of the clutch device, such as gears, bearing, etc., may cause damage may cause damage. The situation. Once these components are damaged, the clutch device will lose normal clutch functions, and the motor will no longer drive the door to run.

Motor failure

Electric Overheating Protection Start: If the motor is frequently activated in a short time, or it is in a overload operation for a long time The overheating protection device inside the motor will automatically start and cut off the power to protect the motor from being burned. Work.

Motor Winding Burning: During the long-term operation of the motor, the insulation layer will gradually age and damage, which will cause short circuit or disconnection of the winding. In addition, unstable power supply voltage, whether it is too high or too low, may cause irreversible damage to the motor winding. SYL-PAGE-BR \”STYLE>

control system Failure

Remote control failure: Insufficient battery battery in the remote control, damage to keys, or external frequency interference may cause the signal to send signals to the motor control system accurately , Make the motor unable to respond to the operation instructions. 27 \”> Control board failure: The control board is the core component of the motor control system, which is responsible for receiving and processing the remote control signal, and the control of the operation of the motor. The motor cannot work normally when the solder joints are loose. -track = \”29\”> Other reasons

> Door stuck: During the operation of the door, the foreign body may be stuck by foreign objects such as branches, stones, and loose screws, causing the motor to load too much and cannot drive the door body normally. When you switch back to the electric mode again, the motor still cannot work normally. >

Power problem: loose power socket, power line break, reserve power supply is not enough , Or fuse melting, etc., will cause the motor to be unable to obtain normal power supply and cannot run normally. >

Comprehensive and effective solution

Check the clutch device

First, carefully check whether the clutch rope is stuck. If there is a stagnation phenomenon, you should gently stretch the rope to ensure that it can move freely.

Check out whether the internal parts of the clutch device have signs of wear or deformation. Once the parts are found, the corresponding parts should be replaced in time.

Manually operate the clutch device, repeatedly switch the electric and manual mode repeatedly to ensure that the clutch device can be completely reset.

Process motor failure

After waiting for the motor to cool for a while, try to start the motor. Generally speaking, the cooling time of the motor is about 5 minutes.

For the burning of the motor winding, professionals need to use professional tools to detect and repair the motor. If the winding is seriously damaged, the new motor may be replaced. /span>

Check the control system failure

Replace the remote control battery and check whether the button can be normal normally Press and play. class = \”SYL-PAGE-BR\” STYLE>

For the control board failure, you should first check whether the components on the control board have obvious signs of damage, such as capacitive drum packs and resistance burning. Maintenance personnel perform well. exclude other problems

Check out whether it is around the door body. Card the foreign objects to clean upAfter foreign objects, manually operate the door body to ensure that the door can move up and down smoothly.

Check whether the power socket is tight and whether the power cord is damaged or disconnected. If you have any problems, repairs or replace it in time. At the same time, check whether the fuse is melted. If it is fused, the fuse of the same specifications should be replaced.

Pay attention to the manual operating overturn car door

Check before operation

Safety confirmation: Before manual operation, you must carefully check whether there are personnel, pets or obstacles around the garage door to avoid collision during the operation, causing unnecessary unnecessary Broken.

Door Experience Check: Sely observe whether the door body has obvious deformation, damage, and whether there are debris accumulation in the track. If the door body is abnormal or orbit is found, these problems should be solved first, and then manual operation should be performed to prevent the door body stuck or derailed during operation.

The operation process Key points

Pull rope operating specifications: When pulling the clutch, it should be slowly and stable to avoid too hard force that causes damage or clutch device failure. If the rope is difficult to pull, do not pull forcibly, you should carefully check whether there is a stagnation cause. >

Uniform force: When manually promoting the door body, we need Keep your hands uniformly to move your hands to move simultaneously on both sides of the door body. p data-track = \”76\” class = \”Syl-Page-Br\” style>

Speed ​​control: The speed of manual opening or closing the door body should not be too fast. Excessive speed may cause the door body to get out of control due to inertia, and it is not conducive to discovering and dealing with emergencies in time. /span>

After the operation, reset

Clutch device: After the manual operation is completed, be sure to reset the clutch device to the electric mode so that the motor is driven normally in the future. If you forget to reset, it will not only affect the electric operation of the electric operation , It may also cause the clutch device to be separated for a long time and accelerate the wear of the parts.

Gate Experience: confirm whether the door body is completely closed and stable to avoid due to the door due to the door At the same time, the body is not closed to cause safety hazards. -br \”style>

When the garage door electric switching manual, when the motor cannot be used normally, we need to conduct a comprehensive investigation and in -depth analysis from multiple aspects, find out the root cause of the problem, and adopt targeted solutions. It is also necessary to pay attention to the above details to ensure that the operation is safe and the door body runs normally. Provide convenience for our lives
