Ryobi RS290G Repair: Why is my Ryobi making a weird noise?

Thu, 12 Mar 2026 00:28:41 -0700

My Ryobi sander started making a strange noise and is not sanding proper. I made sure there were no loose screws, cleaned it and then let it sit for a few hours to cool down as I had been sanding on and off for several hours. Unfortunately none of these seemed to help. What could be causing this and is it fixable ?

Ponceuse Orbital Filaire Dexter 350W - 350OS2.5: Dexter orbital sander pad slipping

Fri, 06 Feb 2026 00:36:32 -0700

My Dexter orbital sander runs and the electric motor spins but for some reason when applying pressure on the pad, the pad hardly spins. Eventually with enough pressure the pad will stop altogether while the motor still runs. This is unrelated to the hook and loop pad not holding the sanding paper disk. Any idea how to fix it? PC350RS 125 mm

Hi, the backing plate does have a visible circular line of chafe however it is not grooved or anything.

There is a center screw on the shaft I believe but I could not find a way to open it as it only can spin with the part beneath it.

The device has no lock button.

I belive this maybe a slipping belt issue, either a gone one or covered in dust. However I cannot find a way to get to it, or find a replacement from this seemingly non existant Dexter brand

DeWalt D26451: Should I try to repair or replace?

Mon, 22 May 2023 10:26:19 -0700

My sander came apart as I was sanding - one of the holes that a bolt attaches the pad to the sander became stripped (bolt isn’t stripped). I think the center thing with three holes needs to be replaced. I’m guessing the thing that sits on the pad rests on also needs to be replaced from the failure.

Is this repairable or do I need to buy a new sander?

Makita BO5041: The sander pad only vibrating not spinning.

Tue, 21 Mar 2023 06:30:59 -0700

The sander pad only vibrating not spinning.

Replaced brake ring no change

The motor is spinning very fast, but the sanding pad is not spinning.

The sander pad can easily be spinned manually.

I dont know where is the connection between the motor and the sanding pad

Parts spinning: #30 inner bearing ring, #33 washer, #34 screw see attached drawings

Parts NOT spinning: , #29 outer Bearing Box , #32 Bearing Box Cover, #35 sander pad and #36 bolt,when assembled these are "sanding assembly" this assembly can be spinned manually but is not spinned by the motor see attached drawings

RIDGID R2740: similar Craftsman 3x21 Belt Sander 315.117260 disassemble for repair

Mon, 31 Jan 2022 00:44:54 -0700

Upon disassembling the sander, I found that the left armature bearing failed, heated, and melted the plastic holding it in place. I can’t get the gear off of the armature in order to take the damaged parts off. I think it’s reverse threaded, but no way can I get it to budge. Help I would think a repair should be possible. Or, have Craftsman tools gotten so bad that this cannot be repaired?

Ryobi RS290G Repair: Sander won't rotate when plugged in after attempt at cleaning

Fri, 23 Oct 2020 10:16:06 -0700

Hello-

I’ve been using my Ryobi Sander (pictured here) on my daugher’s hardwood floor and it’s been going great, if slow. The problem came up when I needed to thoroughly clean it, after repeated overheating, since it became rather clogged. I removed the top velcro pad, the rubber bushing under it, unscrewed the pad, then removed the center bolt from the motor shaft, the bearing and it’s surrounding piece with the 4 screw holes in it, the jagged metal piece that resembles a fan, and got down to the empty compartment which was filthy, cleaned it up, cleaned all the pieces too, and used the repair diagram which is available on the Ryobi website to reassemble it. I followed all of the directions as shown in the diagram, then, attempted to plug it back in and test it, and although the motor does clearly come on and operate, the actual disk does not move at all, and the device won’t operate as it did before. Any idea as to what i did wrong? I have tried taking it apart and reassembling it, to no avail. Any thoughts at all would be greatly appreciated! (link to the reassembly diagram is here:

Ridgid R2611: Bypass the Varible unit

Sun, 16 Aug 2020 03:01:54 -0700

My unit died after a short time of use, I think it could be the varible power circuit board.

How do you bypass the board.

Yhis is a recond unit I bought a Direct Tools.

It is beyound the warrenty date and has very few hours on it.

This is just another example of Ridgid poor quality tools.

Bosch 3727DEVS: Uncontrolled Lurching/Bucking during normal sanding.

Wed, 07 Nov 2018 06:33:59 -0700

Why is my sander lurching/bucking in a random direction? Sanding will randomly lurch out of control from its desired path then return to normal sanding which requires two hands to stabilize it for routine sanding.

Bosch 3727DEVS: Why does my dampening ring keep coming loose and jamming sander?

Thu, 26 Jul 2018 11:39:36 -0700

My dampening ring keeps coming loose, which jams the sanding pad and stops the rotation. I have replaced my backing pad and rubber dampening ring, hoping it was a worn out ring, but the same problem persists. It will sometimes last a couple weeks and other times only a few seconds before coming loose and jamming the sander.

Everything else is rock-solid on this sander so I'd like to repair instead of replace.
