Default Please help - Dewalt Variable speed router - RPM just went beyond the max.

Evening all,

I did a search, and I cannot find anything about it. Google shows only a single reference, so I was hoping someone here could help me out.

I purchase a very expensive router set. Dewalt's variable speed router with a number of attachments. I purchased one, and about 2 weeks later, while routing, I heard a distinct 'snap', and suddenly the RPM went beyond the maximum. The dial no longer worked and the motor felt like it was a run-away. I returned it immediately. Lowes said they'd never heard of such a thing.

Well the replacement just did the same thing, and I'm dying here. I've not used the router in the last 4 months or so, and I'm beyond any 90 day return. Anyone ever heard of this? I cannot imagine that 2 routers would go bad on me personally, and nobody else. I would appreciate ANY suggestions, recommendations, etc.

Thanks very much,
Pete

Pete, I would contact the Company and tell them your story... you may be pleasantly surprised what they will do.

Good Luck!!

Have Fun,

Hi Pete

Just asking, how do you know it went beyond the max , are you using a elec.tack to check the speed ?,, some will run at 24,000 rpm and it will sound like it's going to blow up at that speed...if you push the VS control down to min. will it sound and run at the same high speed. ? did you try a new outlet ?

Pete, would it be silly of me to ask if it's a 110volt model being connected to a 220volt outlet?

Hi, Pete
I would contact DeWalt directly. I assume you have checked to insure that you are plugged into the proper voltage. Also are you using a real long extention cord? A long ext. cord could increase the resistance, and reduce thevoltage to the router.
De Walt will not manufacture some of the parts in a machine. They may be bought from a supplier, and sometimes a bunch will be defective.

if plug in to 220v the unit would pop and not run at all Sound's like the variable speed module that probly is the problum If using a extension cord like a 100 feet I belive it would bog down when cutting It should run at the max speed with out a load If the router has no problum's What model ? If you take it back and see a store manager If they are with you They can give you another one And do RTV I work at home depot It depends if you know some one their Or if their day is going ok And not had some one in their giving them a hard time They take it out on the next person comming in Just happen's

First - wow, thanks for all of the responses
- Yep, is is a 110, plugged into a 110. I've used it, though infrequently, a number of times. It isn't like I was doing really hard work. Using a bowl-bit on white oak. Yes, the router got warm, but certainly not 'hot'.
- Never dropped, never broke a bit
- How do I know it is going beyond max? Good point - I suppose I really don't know that. But *man* does it scream. Runs hard enough to make me think it is going to come apart. Maybe it wont.
- Extension cords. No, nothing real long. wasn't bogging down at the time. Just a <snap> (not a very loud one, but I heard it), and off she went.
- Adjusting the VS knob has no effect at all. It acts like whatever the resister the VS knob manages just broke.

Questions:
Has anyone ever had this problem?
Is this a good router, and I just got two bad ones?
Am I missing something here?

THANKS everyone,
Pete

Hi Pete

I think you hit the nail on the head the VS part is bad, and it's putting the full 120 volts to the motor...you can use it like that but I would not ,,, because you didn't break it I think they will replace the router ....because the VS is NOT working

Good LUck ,goto the top if you need to at the Server Center

I presume that the soft start is not working also, in which case it's as Bob has suggested the control module is outputting full mains voltage. Whatever the cause, it's a case of getting another replacement or a full refund.
