our front door has not been working well for awhile and the reason is:
the internal hinge which holds the spring came lose from being within the hole.
this a design flaw in the pin holding the spring in place. since the front door is used constantly the hinge receives constant use… the pin should have a clip on each end holding the pin place….also the spring should be much stronger than it is…
5 minutes later the spring and the door hinge is back into one piece and working well…
