It seems like something is preventing from going all-away back... Looks like something fell over and is preventing the drawer going all-away back.

Take the drawer off the track out and look behind there, if nothing there, check the slider itself make sure it goes in all-away back.

Did you recently remove the drawer? This happened to mine. I don't remember where exactly the little tabs are but there are little tabs on each side located somewhere on the track. Push them in and slide the drawer at the same time and I think there was a click sound or something. I circled two areas for you to check but if theres no little tabs there keep looking around and see if you see any.

When you pull the drawer out there on the inner track there is plastic lever, push that lever down and slide the drawer out. (in the picture above the lever is right before that second circle on the inner track)

Thanks for your help, I have pulled the drawer out and confirmed nothing is behind.

I am having difficulties putting it back on the rail, the soft closing doesn't work and the drawer doesn't fully close.

Looking at my diagram, there is a small piece (the bar with 5 squares), do I need to push it to the end?

How about the slider itself? Do I push it all the way in when mounting the drawer?

Thanks!

Lindsey, you have undermount drawer slides. OP has side mount slides. Two whole different animals.

SW Wong, did you check all the mounting screws in the slides to make sure that they are properly seated? If one is standing proud, that could be the problem. Check all of the screws, the ones that mount the slide to the cabinet and the ones that mount the slide to the drawer.

I have some Accuride and KV side mount slides but no soft close versions. When I remove and replace a drawer, I have to get kinda' tough and force the drawer to close. For some reason, the slide has quite a bit of resistance to closing. After that first 'force to close' , the drawer functions fine. Again, I do not have the soft close versions.

Also, check the slides for a manufacturer's label. If these are a generic, no-name slide, then the chances of just having a bad slide is probably higher than with a recognized brand. You may end up needing to replace the slide. Not a fun job but not all that difficult to do, either.

Thanks all, I have managed to fix this - I am using the generic slides.

The gas pistons were disengaged so I have pushed them back up so the the slider (from the drawer) connects it back.

Oh, good for you! And thanx for the update.

Well who knew there were different options for soft closing drawers! (Clue: name starts with L and ends with indsey)

Glad you got it figured out, OP!

I fixed my drawer in just a few minutes. It is so easy! Thank you, lindsey_9002 !

You’re most certainly welcome! Glad I could help @Jeani Masching !
