Can’t remember how long exactly I’ve had my DeWalt 735 planer – but at least two years. I’ve never had this problem before but when planing face grain boards my planer’s fuse pops. I take small bites on each pass through.

I plane all of my end grain boards with zero problems and until just the last two weeks or so, I’ve never had problems with face grain boards.

I’ve looked through the trouble shooting portion of the manual and I have new blades, I use small bites and I reduced the feed rate to 1/4 fit/min. Still fuse pops consistently.

I’ve taken the cover off and looked to see if anything looked out of place, or worn, or if a chip was lodged in anything and I found nothing out of the ordinary.

What essentially happens is about 8 or 9 inches into a face grain board the motor sounds like it is bogging down and then the fuse pops. I don’t take large bites, in fact, I think most of you would say I should be able to take slightly larger bites on face grain.

The fact that this only happens on face grain really is a head scratcher for me. I would think it would happen on both types of boards.

Just for some facts, I use walnut, hard and soft maple, cherry, mahogany and ash. My glue ups are nothing spectacular but my joints are solid and I don’t have a lot of high or low spaces – so I usually don’t need a lot of passes to get the board cleaned up and ready for final sanding.

The only thing I can attach to this issue is that I had to replace a spring a few weeks ago but that did not involve any real mechanical magic and no tear down to replace it.

Once the fuse pops it goes right back in with no problems.

Any ideas?

Hi Betsy,

That sounds odd. Forgive me if I my question is too obvious. I know you said that you don’t have a lot of high or low spots, but I wonder if the board is warped or bowed and it is somehow trying to take a bigger bite as goes through the machine. On the other hand, that spring sounds pretty suspect.

I am interested to know what you find.

When you say the fuse, are you talking about the circuit fuse/breaker, or a reset on the planer itself?

Hi Betsy,

It sounds like one of those thermal overload cut outs if you push it in after it cools. I have one on my metal chop saw and I know when I work it too hard that the thing will pop. If you are not working it real hard when that happens. It might be a bad fuse/cut out.

I know you probably have done this but could the table need waxed. There’s a lot of surface area on the face grain that could create friction.. Also, what Charlie said about a warped board.
If it’s rough lumber, it is possible that the thickness is varying enough to bog down the planer.

One other thought, while I was typing, it could also be a weak breaker. The breaker is designed to P”pop” at a certain amperage but sometimes, thru use they will pop at a lesser amperage.

I thought about the warp issue – but I’m certain that’s not the problem. However, the more I think on it – the high and low spots on my glue ups – while I don’t think they are big enough to cause an issue – they might be. I’m going to start keeping a note pad by the planer and measure the high/low spots and see if I can find a trend.

I did wax the planer – I thought that maybe the friction from the glue joints may have been a problem – I now have a very shiny feed table – but still the popping.

How would I determine if the planer’s breaker is weak – is that something than I can check by getting a gadget at the home store?

i don’t know much about the electrical breakers – but I have had my home circuit box inspected when the outlets started their burn a few months ago. They did replace one breaker that they thought was bad, but that controlled the master bedroom and bath.

Conifur – it’s the fuse on the planer not in the house circuit box.

Charlie – why would the spring be the issue? Could the fact that the spring broke be an indication of a problem in another area of the planer? I was thinking I just had a bad spring.

If it comes down to being a bad fuse in the planer itself – is that easy to fix?

thanks for the help guys. I’m glad you guys are around to give some help – these type of issues fluster me a bit (maybe a lot).

I dont know how a reset/button on a machine works, I dont think by amperage over draw, but my guess if all else is working in order it is bad. I would either get a new one from DeWalt, or bypass it and see if the main circuit breaker trips. If you would bypass it and the main trips then you have a PROBLEM. I do know when a main trips multiple times it weakens and will trip easier each time.

just a thought betsy

perhaps check the carbon brushes (replaceable)
on the motor itself
they do wear down over time
might be they are almost done

A good thought on the brushes but on a 2 year machine unless used extensively, doubt it being worn. I have 2 Delta table saws from the 80s, I bought used, I dont know how much they were used, but I just had to replace the brushes on one of them, they have an over load button, but that did not trip. I smelled burning motor stuff, acidic, and yes no power while cutting some easy wood. Brushes were still good but one was cracked and chipped. So I would check them at the least.

I would still call DeWalt customer service and talk to them, the only fly in the soup here is the spring change. They have more problem solving knowledge on there stuff then us jerks here speculating.

Not sure about checking brushes – I know they exist but would have to check the drawings to find them. My dad was a mechanical genius – but I stepped out of line when those genes were passed down – so I’m pretty sure if it is anything to do with a motor I’m going to have to take it somewhere for service.

I can say I’ve not smelled any burning smell and I’ve not seen any sparks or anything like that.

If the magic smoke is still in the motor, then you’re good.

Betsy, I definitely recommend you talk to customer service. My DW735 lasted 15 years before I had to replace it earlier this year. No way your unit should be failing so soon … my vote is that you’ve got a bad breaker, but my vote means nothing. Talk to a smart person, and then enlighten us!

Not sure if this has been checked already, but could it be that the motor brushes need replacing? I have a 735 and if I remember right, it has a universal type motor. It could be that if the brushes are worn or need replacing, that the additional resistance results in a higher amperage draw than normal when the motor is heavily loaded, this tripping the breaker.

I would also try replacing the fuse breaker. Not sure how at home you are with
electricity or how the one on the machine is wired in, maybe you have one
with similar or lower specs lying around the house and could wire it in
for a test.

I’m betting the wood is bowed in some small fashion.

I has similar issues when first getting used to my DW735. Was super careful about measuring the end of the board and not taking too big of a bite. But every so often it would sound like something was holding the feed back and CLICK, there goes the circuit breaker on the planer.

Finally realized I needed to raise the cutters so I could JUST slide the board all the way thru, and that’s how I started finding the high spots. Many times I have to hand feed the wood till the rollers grab, so it will get the high spots first.

I’m going to talk to the customer service folks and see what they say.

Joe – I think I may do just what you did and then with the power on – see if that trips the breaker. I may be thinking that my glue ups are better than they actually are – which is probably not far off.

Either way – I’m going to contact service and see what they say.

Thanks all
