MIWA LB.10DAF + U1 Door opening / closing abnormality Inspection and repair

"Doors do not open from inside or outside"

It was a request from a woman who moved in today.The door won't open with the key or thumbturn.It was like contacting me after I moved in and organized my luggage.

I often have troubles in this situation with women, so I was moving and thinking that it might be caused by negative pressure.Since the property is 6 years old, it is unlikely that the lock case is broken. (Although there was a case where the cam mechanism of the lock case was damaged due to the same trouble a few years ago.)

Upon arriving at the scene, the client was indoors.At the same time as having the door open from inside, I also pull the door.

Then, the door opens normally while feeling a large negative pressure.A petite woman was born from inside. (This negative pressure may be severe for women)

I didn't feel any misalignment with the strike, so it was caused by a large negative pressure.

It is a one-room apartment with 6 tatami mats.The 24-hours fan system in its narrowness was a considerable negative pressure.You can hear the loud noise of the ventilation fan coming from the dressing room.

I wish I could make adjustments, but I just moved in today, so please check it out slowly.

The work is completed by adjusting this negative pressure according to the power of the woman. (There are similar cases for young men)
