Ok here's a weird one. Intermittently the doors open all by themselves (it's not a DCL band I already replaced a broken one). When they do open and close it is very very slow, and the door open and close buttons have zero effect. When the doors work normally from a hall or car call they work perfect and the door open, door close, and car call button at that particular floor work as intended. The car can sit there for 4 or 5 minutes and not do it, and then it will do it two times in a row. Once the doors go closed I can put a hall or car call in and everything works as it should until it sits there for a bit. I have zero faults showing on the World tool either.
