Default Porter Cable 690LR 8 No "What to do" support

I have a Porter Cable 690LR 8 which I was using a 1/2" x 3" straight bit to trim a clued up edge with. 1/16th max amount of stock removal, when it just stopped. I was just getting started and the router showed no signs of being over loaded. At which point I started looking for a reset button and there isn't one. So I went to the Porter Cable web site hoping for some trouble shooting support and the only thing I could find was a listing of service center to send it in to. But I don't want to send it anywhere, I want to do a rudimentary review of the situation. Where do I go for Porter Cable support?

Tim this article might help: Diagnosing Electric Power Tools 101 : eReplacementParts.com

The sudden stoppage is not a good sign. Normally an armature problem is preceded by a loss of power and rpm but a sudden stoppage is most likely an electronics problem but looking through the parts list I don't see any electronics. Does it have soft start or speed control? Porter Cable 690LR Parts List and Diagram : eReplacementParts.com

Hi Tim, you didn't say you smelled smoke,as in a burn-out,so it could be a simple blown fuse.I hope that's all it was.Good luck,Jamesjj

Tool parts direct shows a speed control...obsolete...part 4A...

Porter-Cable 690LR 1-3/4 Peak HP Router Parts | Tool Parts Direct

It might be that or the switch or brush wiring. Bypassing speed control might work...one side of line coming out of switch to hot brush, other brush to return.

Check for physical first...switch, brush wiring at solder joints, etc.

No, there is only one speed and the brushes, which are easy access, look great.

No smoke, and the fuses are all fine.

I would open it up and check all wire solder points and connections.

Don't forget to test the switch...

And the power wire. Sometimes a wire will break around the rubber boot. Do you have a meter or other device to test continuity?

Also make certain that the power outlet that you are using still has power. Plug something else into it to test it. Don't take the router apart until you are sure that the problem is really the router.

Do you have an electrical continuity tester and/or a volt meter? One of these will be necessary to test the power cord, internal wiring, switch, and motor. A cheap, but quite effective multi meter is available, and sometimes free, from Harbor Freight.

Yes to everything. So the brushes are very easy to get to and are in great shape. I'll pull the hood and test the plug and start switch which should both be easy checks, albeit the router isn't that old and there is zero dry rot. Seriously, it looks great. But I'm comfortable with the testing equipment, and using it as a paper weight has no appeal. Just wish there was a DIY maintenance manual online, like the one for the cloths dryer. Step by step in order of simplicity to access. Guess that wont be in a DeWalt Companies future any time soon. I'm sure I can wing it to a degree. It's just that routers always struck me as a "How did they get all that in there" kinda tool and once I take it out, I'm concerned with getting back in. It makes me mad to comply with the extra cost, but there's a DeWalt repair facility a block from where I work and I like the router so I'm gonna check the switch and power cord and then if it still doesn't work, I'll hand it over to the professionals. Thanks for the help.
