Okay, it’s not ailing, it died :(

The last few times I was using it, the pitch (scream) seemed to waver a bit but I just put it down to dirty power. I fired it up last week and silence…...nothing. Tried the breaker/reset button, checked the main breaker, plugged it directly into a known good power source, took the top off and dust shroud and cycled the motor by hand so it wasn’t jammed and still nothing. I ordered a new power switch because I read that it might be that but alas, no.

So now I’m down a planer and it’s going to be a week or two before it can be repaired so I’m not a happy camper. Only silver lining is I’m heading on vacation to Cuba for a week so the second week it’s in the shop will be while I’m away.

Has anyone had a DW735 die on them like this?

I repaired one where the brushes had been worn down past the point of replacement. This usually give an audible warning before creating an open circuit.

I read about some micro saftey switches under the dust covers that can also go out.

How long have you had it? How deep of cuts do you take with it? What kind of wood goes through it? Are you running a long extension cord on it?

I would check and see if the switch is working by seeing if the motor is getting power when the switch is on. If it does not even sound like it is starting, then I would first suspect the switch or breaker being bad. Does not look like it is too difficult to replace either of these.

Mine is running good after 6 years or so. I put about 200 bdf through it a year mostly red oak and take light passes. I look at it as mainly a finish planer

I should have added that I checked the brushes as well and there’s lots of life left in them.

I purchased a micro switch as well but after the dismal and disappointing failure of the new switch, I didn’t even bother trying the new one.

I’ve had it for about 2 years so still relatively new. All kinds of wood go through but always very shallow cuts, nothing over 1/32”.

As of now, I flick the power switch on and there’s nothing, just dead silence. My only other two things I can thing of is the micro switch or the breaker/reset button.

Have you tried bypassing all the switches and existing cord entirely and wire the motor directly to an extension cord?

Haven’t bypassed anything yet. I was betting the farm on the power switch :(

Just spoke to Dewalt (Ottawa) and the tech (Andy) suspects wiring to the motor so off she goes…..

Well, Andy from Dewalt just called and the news isn’t good.

Bearings shot, armature shot etc so $300 + tax (Cdn) to repair.

Options are to write this off as a doorstop, get it repaired and carry on or buy bigger and better.

Thoughts?

If you find yourself often wishing you had a bigger planer then I’d go the bigger and better route. If not, then I’d just bite the bullet and fix the one you’ve got. Personally, I like everything about my DW735 except the noise level. Did Andy have any suggestions as to why your bearings and armature failed after such a short period of time?

Bigger is always better, or so I’m told :)

Lots of times I find it a real pain in the but having to use the drum sander for pieces larger than 13” but so be it. I either fork over the $$$ for a nice size machine or like you said, bite the bullet for now and get my Dewalt back. I like the Dewalt as well but figured it should have given me a little more lifetime (1.5 – 2 yrs) before a major repair.

Definitely go bigger if you can afford the cash and space expense.

You could always sell the 735 for parts…

Sorry to hear about that, I know the labor alone for replacing bearing on anything requiring a lot of disassembly can be high. Armatures are all over the place, some reasonably priced, some outrageous. When I fixed power tools professionally, I would have to replace 2 DeWalt armatures for every one from all other manufacturers combined. Not sure why this was, but discerning none the less. I hope this was a fluke for you as I have a DW734 that’s served me well so far. If it kicked the bucket tomorrow, I’d be looking for something larger. I’ve had my eye on the Grizzly 20” for a while now, just can’t justify it with a working planer and the infrequency I actually need additional capacity right now.

How old was your DeWalt when this happened?

Less than 3 years old it should be covered by warranty.
