I posted on this group a few weeks ago about having a problem with a door. The door wouldn't close with the automating closing mechanism. After trying several things, I found that there are two causes.
First of all, the hole in the door case that should receive the latch when the door closes wasn't vertical to the ground. This was fixed.
So now the door closes with the automatic mechanism - most of the time. Sometimes the latch will reach the hole (as it moves with the aid of the mechanism) but when it touches the case it won't retract inside the door.
This doesn't happen always, sometimes you can just push the door away and let it close again and it will do it fine.
Why does this happen? I suspect there is too much friction there, so a little oil should fix the problem. THe thing is, we keep putting oil on that damn latch and it's ok for a couple of days and then it starts doing its thing again. Why?
Isn't there some other way to improve it without just putting oil on it? I've had the latch changed, I've had the hole in the case changed, everything seems to work for a couple of days and then it starts malfunctioning again.
I've thought of slightly sanding down either the latch or the metal that it touches on the case as it closes.
Any other suggestions?
