The electric roller shutter may jerk due to several reasons, such as an obstruction in the tracks or mechanism, misalignment of the shutter panels, or a malfunctioning motor. Additionally, worn-out or damaged components, such as gears or springs, can also cause the shutter to jerk during operation. It is important to inspect and maintain the roller shutter regularly to prevent jerking and ensure smooth functionality. **

The electric roller shutter is broken because the motor is not functioning properly. This could be due to a malfunction in the motor itself, a problem with the electrical wiring, or a fault in the control system. The motor may need to be repaired or replaced, and the electrical connections and control system should be checked for any issues. It is important to have a professional inspect and repair the electric roller shutter to ensure it is safe and functional. **

There could be several reasons why the electric roller shutter is not moving anymore. It could be due to a power outage or a tripped circuit breaker, which would prevent the motor from receiving power. Another possibility is that there is a mechanical issue with the motor or the shutter itself, such as a broken gear or a jammed mechanism. It is also possible that the remote control or switch used to operate the shutter is malfunctioning. It is recommended to check these potential issues and troubleshoot accordingly to determine the exact cause of the problem. **

The jerking of an electric roller shutter can be caused by a few different factors. One common cause is a malfunctioning motor or gearbox, which can lead to uneven or jerky movement. Another potential cause is an obstruction in the shutter's tracks or guides, which can cause the shutter to move unevenly. Additionally, issues with the electrical wiring or control system can also lead to jerking or erratic movement of the shutter. Regular maintenance and inspection can help identify and address these issues before they lead to jerking or other problems with the roller shutter. **

There could be several reasons why the electric roller shutter is not going down. It could be due to a malfunction in the motor or the control system. There may also be an issue with the power supply or the wiring. Additionally, there could be an obstruction or damage to the shutter tracks or mechanism. It is important to troubleshoot and identify the specific cause of the issue in order to effectively address and resolve the problem. **

No, the electric roller shutter does not go down by itself. It requires a person to operate it using a remote control or a switch. The electric roller shutter is designed to provide convenience and ease of use for the user, but it does not have the capability to go down automatically without human intervention. **

The electric roller shutter may slide down after replacement due to a few possible reasons. One reason could be that the new replacement part is not properly aligned or installed, causing the shutter to slide down. Another reason could be that there is a malfunction in the motor or control system, causing the shutter to lower unexpectedly. It is also possible that there is an issue with the power supply or wiring, leading to the shutter sliding down after replacement. It is important to have a professional technician inspect and troubleshoot the issue to determine the exact cause and make the necessary repairs. **

There could be several reasons why an electric roller shutter doesn't stop at the set point. It could be due to a malfunction in the motor or the control system, such as a faulty sensor or limit switch. It could also be caused by an obstruction in the shutter's path, preventing it from reaching the set point. Additionally, there may be issues with the power supply or wiring that are affecting the shutter's ability to stop at the desired position. Troubleshooting these potential issues and seeking professional assistance may be necessary to resolve the problem. **
