First of all, the first step is to check whether the aluminum profile door accessories are damaged, whether the aluminum powder coated door equipment is loose or the sealing strip is aging or the bottom of the pulley is smooth. If these accessories have problems, all you need to do is to replace them directly, which can not only save you a lot of time and effort to do the maintenance but also saves a sum of the maintenance money.
Second of all, we can hear if the sound of aluminum doors is normal when they are being pushed on or pushed off at ordinary times. Most of the control systems of the aluminum profile door now use electromagnetic relays as the control equipment. A clear “tick-tock” occurs when the relay contacts are switched. If there is no sound or abnormal during the switch, after determining that the relay driver is without any problem, it is basically certain that the relay is the reason why the aluminum doors that can’t be used normally. If the aluminum profile door is installed with an induction lock, it is necessary to test the control circuit at last.
The last but not the least, as for some key components of the aluminum powder coated door, the experienced master can figure out which components are aging and damaged, and whether it needs to be replaced. But for some common problems, for example, aluminum powder coated door that can not slide normally may be a real problem. Usually, this is caused by corrosion of the outer part of the window frame. So the first step is to make sure the aluminum powder coated door frame is not closed and that the frame track is not bent. The second step is to use lubricating oil to thoroughly smear the track of the aluminum powder coated door. The third step is to refuel the frame clamp, spring and any other movable parts until the frame is loosened up and the aluminum powder coated door can be opened.
