Question: Orbital Sander

joe b

Why is the pad spinning as fast as the motor and not orbiting?

The #26 p/n 151553-00 "Dust Seal/Brake" has likely worn out and needs to be replaced. See the manual under "Tool Care" 2. for the procedure. On my DW423, #24A p/n 151281-08 "5" Sander Pad Hook and Loop(Velcro)" was worn/damaged and needed to be replaced. Probably just replacing my #26 would have resulted in it wearing out very quickly.

Question: Lost Power

speb

On a hot day doing a usual light job I noticed heat in hand hold, no smoke, and speed is fine until I apply disk to work. Then No power and drops RPM's Tool has very low time of use.

Question: DW423 Dropped

Andrew

I dropped my DW423 sander. Now it is just dead. Is there a typical component that is subject to impact damage?

Hi Andrew,

I would first inspect the motor brushes. They may have been damaged in the fall. Sometimes a fall can also break the brush holders. Look for any damage to the switch. Those would be my guesses.

I hope this helps!

Question: Both Stopped Mid Operation

George

I have two dw423- one as a spare. Spare used couple hours total. Both just stopped for no reason, power at the plug, power through the switch and to the brushes.

I also have 2 of the DW423, both of which stopped mid project without so much as a groan. After doing some testing, I suspect the problem is the control module (variable speed control). Couldn't help notice on the parts listings that this part is "obsolete". I suppose that means they don't make it anymore, and since it was probably defective design (given that we have 4 dead units), I suspect they ran out of replacements very quickly. Would love to get an answer from Dewalt but notice they left you hanging for almost 2 years without a reply.....

Hello Ken1234,

You would think that after a company stopped manufacturing a product, because of a faulty part they would figure out a new way to get the tool working without that part or even design one that would last. And after they stopped production of the to tool keep all the parts on hand for a few years until a majority of the tools got so worn they wouldn't be worth repair. But I guess that would make to much sense

Just saying,

I've owned a DW423 for 10 years, has and is still an excellent machine. It has run perfectly until today 12/27/08 when the hook pad finally gave up and blew apart while finish sanding a table top. I have had absolutly no problems with this tool, and the hook pad giving up seems to be normal ware for the amount this tool has been used...

Good Tool! You're fortunate not to have had to replace the hook/loop pad sooner. It is a normal wear tear item.
