MIWA PSDN.WD5113-FDG two identical malfunction repair (common name: "SENBEI", Pancake)

"Failure to lock and unlock the key of the entrance door"

It is said that there are times when it is difficult to close the key. When I arrived at the site and interviewed again, I was told that this phenomenon often occurs in the evening.

This entrance door was in an environment where the western sun hits strongly. Aluminum doors have high thermal conductivity. As a result, the door seems to warp. Moreover, the door gasket was considerably deformed.

As I continued to listen, I heard that I put oil in the keyhole myself. It was indeed CRC556.This is no good. Don't do it.

It must be disassembled and thoroughly cleaned. I explained that CRC556 is not suitable for keyholes, and after understanding it, I disassembled it.

Next is adjusting the door. However, the deformation of the door cannot be repaired, so I adjusted the position of the strike to improve it. Is this front door insulated?
