KV GS4270 Drawer Slides No Longer Fully Close

DerbyDad03 · 2021-01-19T18:28:18+00:00

About 5 years ago I installed 8 sets of the Knape & Vogt GS4270 full extension, soft close drawer slides.One set, the one on the most frequently used drawer, no longer fully closes on its own. When I give the drawer its normal push, it glides to about 1/2" from fully closed and then stops. The soft close mechanism does engage, it just doesn't pull the drawer all the way closed. A gentle push gets it closed, but it's a "manual close" i.e. I don't feel the mechanism taking over.I can "fix" the soft close issue by fully extending the drawer (the standard full extension reset method) but this only solves the soft close issue for a day or two, probably some X number of usages.I called KV tech support and other than "make sure all the screws are tight" and "make sure nothing has shifted inside the cabinet", he had no other suggestions. When I asked about lubrication, he was pretty emphatic about not trying that.Unless someone has a suggestion, I think replacement may be my only option.

LOL, So some how or another I installed one of the drawer units, in the island, that was supposed to go somewhere else. One would think it would be obvious as to which went where but the one for the island had to be a bit narrower than the opening because of electrical conduit on one end. Sooooo the really generous fit did not strike me as odd. But then I had the last unit to install and it was about 1/2" too wide. Out comes the island unit and into the last cabinet. Just like I measured. LOL. And so on.

I hate wondering if I looked at the right side of the inch indicator... Was it 24.5" or 23.5". :~0

At least you realized what you did wrong pretty quick.

Sure would have sucked if you had thought that you built the last unit too big and went home to build another one. :-0

Wondering is bad enough but it's worse when you cut to the wrong/short side. BTDT

MTZ fixed it. 1 year ago

I had the same problem for the last 25 minutes. Fixed it.

I removed the drawer below to compare slow close red and black gear in the back.

In the front of the red gear, half way up, there is a 1/4 in switch. The black switch moves the internals some. If moved down it releases the retrieval system.

Check that the one on the left rail is doing soft close and check that the right side is set to do soft close. (This can be seen when you push the cabinet rails in yet they will stop about an inch out.

It seems that the rails slide close yet sit out an inch. So with the drawer out both side should slide back and the stick out an inch. The cabinet rail will sit out until the drawer rail slides past this point and release the gear to pull the drawer in. Some how both side needs to work to pull evenly.

I may have had the left side drop down and not pull.

I set both sides to soft close and it worked on one drawer. Then the next one didn’t close correct. I looked in and had the right side drop out of soft close. I pushed the switch up and set it again. Now they all clothes fully.

That may depend on the user's level of precision (or perhaps OCD ? ;-)

However, OCD is a excellent trait for a dentist. A few years ago, I got a call from my then dentist "Don't bother coming tomorrow. Your new bridge arrived today and I'm not happy with it so I sent it back. I'll call when the replacement gets here." The replacement fit fine, both on the tooth posts and in mesg with the teeth avove it. My current dentist is close to that level of OCD - but then he was recommended by the previous dentist ;-)
