With the wide application of the fast rolling shutter door, many friends will find that the fast rolling door will not move after using it for a period of time. What is the reason for this? Today, I'd like to share with you the reason why the fast rolling shutter door doesn't move.

      The first reason why the fast rolling shutter door does not move: the power switch of the fast rolling shutter door is damaged, and the controller switch of the fast rolling shutter door will be damaged, which will lead to the power failure of the fast rolling shutter door, which will lead to the motor unable to rotate. At this time, we need to check the power controller of the fast rolling shutter door, or replace the power controller with a new one to solve the problem.

      The second reason why the fast rolling shutter door does not move: the relay coil of the fast rolling shutter door is damaged or stained. The damage of the relay will also lead to the failure of the fast rolling shutter door. We need to replace the relay with a new one or polish the electric shock to help us solve the problem.

      The third reason why the fast rolling shutter door does not move: there is a short circuit problem in the wires and lines of the fast rolling shutter door. This fault is caused by the external environment, not the problem of the fast rolling shutter door itself. Therefore, as long as the power supply of the fast rolling shutter door and the rolling shutter door motor are powered on after the fast rolling shutter door does not work, it can be judged whether there is a circuit problem, and the circuit fault can be checked in time, solve the problem.

      The fourth reason why the fast rolling shutter door does not move: the running time of the fast rolling shutter door is too long, which will cause the thermal protection to be disconnected. In this case, don't worry, as long as the motor temperature drops, you can restart it.
