Last night my DW 733 planer was running fine. I went to run it
tonight and it does not run - at all.
I pulled out the multimeter and checked everything I could reach
easily.
120v is getting to theon board circuit breaker, to the switch, and out
of the switch when it is flipped on - but the motor doesn't do a
thing.
I suppose that I can take it apart and follow the wire as it goes out
of the switch to see if it came loose or broke. But I'm not sure how
to disassemble the unit to get that far. I don't see an easy way to
do this. Do I need to take the top off and remove the guts from the
top?
Any help is appreciated.
Its strange that it went from fine to dead overnight without being
touched. I would think that if something broke, it would do so while
being used.
I am in the middle of building kitchen cabinets and cannot wait for a
service center to fix it. I either need to get this thing running
tomorrow or I will have to buy a new one. OK, thats not so bad
considering that Delta, Ridgid, and of course the Dewalt 735 are very
nice, but I really don't want to drop the $400 - $500...

You could probably find an exploded view. Once you figure the easiest
way to the motor connections, you can look for 120v there.
Have you checked the motor brushes?

Possibly the brushes needed to be reseated?
Glad to hear it's working!
I love buying new tools but hate replacing existing tools.

I was thinking the unit was moved and a brush got knocked ajar.
Chances are, if they look OK, they are.

I have a 733 and there's a part of me with the same wish. I have to lie
down till it goes away.
In all the troubleshooting I did back when I fixed office equipment, if a
piece worked yesterday but didn't today, it was almost always a bad
connection someplace. If you were getting power to the unit but you
couldn't even hear a _hum_ from that thing, my gut says something was
halting the flow to the motor.
My gut also says you either re-established the connection when you took it
apart and put it back together, or you still have a connection that's only
half secure. I've seen fuses that work *sometimes*. They actually had
severed filaments but the ends touched. Temperature and humidity would make
the ends bend away from each other and then come back.
Best of luck,
Dan

a lot of modern power tools have brushes that shut the tool down when
they get short rather than grinding them down to the springs.
I don't know how many hours of run time the brushes on that machine
are supposed to get, but you might be able to find that info on the
web.

I checked the brushes and they *look* fine, but I'm not really sure
what I am looking for. There's a line in the carbon near the spring
and the brush measures about 7/16 from there to the curvy paret.
Would they keep the motor from running at all and would they just give
out overnight?

Brushes was my first thought as well.

I guess the DW735 is going to have to wait. I checked the brushes
again - for the third time. They still looked good. I couldn't trace
power past the switch without taking the motor off.
So that's what I did. After taking off the top, the chains and
sprokets, the drive belt, and a few other items. Thankfully the
DeWalt website has some nice videos that show all of this stuff step
by step.
Once I got the motor assembly off and the housing into two pieces, I
discovered that I couldn't get any further into the wiring. But I did
notice that I could stick the probes of the multimeter through some
ventilation slots and check the terminals that bring power to the
brushes.
Anyway, when I flipped the switch, the motor ran. I have no idea why
nor do I really care at this point. The unit went back together
without issue and I'm up and running again.
Part of me really wanted a new DW735, but the 733 does a good job and
I saved $500 and lost an afternoon. I've will order up a new set of
brushes and hope that is where the problem really was.
Thanks to all who responded.
