What\’s wrong with the garage door that won\’t close?

Why can’t the garage door close?

Recently, some netizens asked about the Kunming Haydn garage door, why the door cannot close to the bottom? Netizens said that there is a gap at the bottom every time it is closed, but the tracks and wheels operate normally, and there is no problem with opening the door. Only when the door is closed, it does not fall to the bottom every time, and after careful inspection, there is no unevenness on the ground. , there is no obstruction at the bottom, and the gap between the door panel and the ground is about one or two centimeters after closing. I am worried that thieves will take advantage of it, so I want to know how to repair it? Based on the garage door owner\’s introduction, we initially determined that the downward stroke of the garage door was not adjusted to the bottom, and the stroke only needed to be readjusted to return to normal.

Adjust the stroke of the electric garage door without landing as follows: First find the FUNC control button on the motor, press and hold it for about 7-8 seconds until the indicator light flashes, and then press INCbutton. At this time, the motor will run in the direction of opening the door. Then continue to press and hold this button. Release the button when it is fully opened to the appropriate position. Press the DEC button. At this time, the door-opening position (ie, the upper stroke) is fixed. The next step is to perform the downstroke operation. First press the FUNC button. The indicator light will flash continuously at this time. After the indicator light lights up again, you can proceed with downstroke debugging. Wait until the garage door falls to the ground and there are no gaps in the garage door when you look inside the garage, which means the debugging is complete.

If the garage door motor cannot move the door body at all, it means that the torsion spring is weak or has no tension at all. At this time, the motor stroke debugging should be stopped immediately to avoid damage to the motor and greater losses. Moreover, you should find a professional garage door manufacturer to arrange for after-sales personnel to perform door-to-door repairs. Never use brute force to lift the garage door, otherwise the door panel will deform or the door body will suddenly fall down, which is very dangerous. If the garage door falls down and falls, It will cause serious safety accidents to people, so remember.
