Broken returns springs, stretched cables and worn pivots show up as a handle with no resistance or a door that needs a slam. Door hardware is handed — left and right are different parts. Check the side marked on the listing against the door you are repairing.

Check the door alignment after fitting, as a worn part often masks a hinge that also needs adjustment.
