Automatic closing drawers or self-closing drawers are drawers that retract back into the cabinetry with a simple nudge. Once nudged, the mounted runners -- whether side-mounted or under-mounted -- pull the drawer slides in. If the drawers are getting stuck or not retracting as they should, minor adjustments may be needed to restore them to working order. If the runners are working properly, but you wish to raise or lower the drawer slightly, you can adjust this as well.
Remove the drawer from the mounted runners. If the drawer does not remove easily, look underneath the drawer for any obvious obstructions in the hardware preventing removal.
Clean the metal slides on the drawer with a soft cloth. Remove any debris or dirt. Clean the mounted runners with a soft cloth. Be careful not to wipe away any lubrication. Spray the slides and runners with compressed air, if available, to help clean out any dust and debris that may be causing trouble.
Tighten the screws used to mount the runners. Loose screws can interfere with the automatic closing drawers, causing friction or preventing the drawer from shutting completely.
Place the drawer back on the mounted runners. Locate the levers underneath the drawer on the front of the retaining clips. Hold the lever and raise the drawer to adjust the height and let go when the desired height has been reached. The height adjustment mechanisms will vary by manufacturer and mounting type.
Unscrew and reposition the drawer dampers if the automatic closing drawer is slamming shut instead of soft-closing. If the piston on the dampers is worn, the dampers may need to be replaced.
