Dewalt DW735 13 inch planer breaker tripping fix

This is a simple and quick fix for the Dewalt DW735 13” planer. If your circuit breaker on the front is constantly tripping this is how you stop it. Once replaced. Be sure to get to the root of the cause. Most likely dull blades or possibly a short in the wire like seen in my video.

Hi would you happen to know as soon as the machine is switched on it trips the electric immediately on a dw733. Thank you for any help. Derek

[@loveofthegrainworkshop2891]

Yes! The wiring inside behind the switch & circuit break below are likely melted & crossing each other. I’ve had this happen multiple times to mine. Much like you can see in this video it was definitely a culprit. Open it up, while unplugged & check. You’ll need to cut the bad wires out, splice in new ones if needed for length & swap out the power switch & circuit breaker on the unit. Should be up & running again

Don’t be a dumbass and always unplug when working on machines. Good video thanks

So we have this planer in our shop, and we have this issue with the circuit breaker after swapping blades. Why would we invest in a helical blade and not a better planer?

[@loveofthegrainworkshop2891]

Good question, the byrd helical head is around $500. Vs upgrading the planer to a more robust one which would probably be something by Grizzly. That’s $1500 minimum for the next best thing.

Excellent and informative video. I just had a problem today and your video gave me a hint of what might be the problem. The wood was feeding through, but the blades stopped spinning and cutting. I will change the blades and see if that is the problem. Perhaps the breaker went off because the motor overheated. Here is something I noticed and can't figure out. I noticed that the metal on the planer body (not the circular cutter head) near the screws that hold the blades has chips missing. The blade is not touching the metal body, but perhaps the chips flying off are causing the metal to chip. Ever heard of this? I also think that I will replace the straight blades with a helix cutter. Anyway, thanks for taking the time to post a very good video with good camera clarity.

[@loveofthegrainworkshop2891]

Sounds like your belt broke or maybe your bearings on the cutterhead. That would be the only reason I could think the cutter would stop but rollers still feeding. And definitely sounds like the blades chipped the body as they flew off. Or shrapnel from metal in the wood.

Load is *not* the power coming in. Load is the piece of equipment that's being powered, thus putting a *load* on the circuit. Line is the power source.

So have the DW734 and I am having the same issue. The person I bought it from had worked over the first side of the blade pretty bad but the second side was totally new. After doing one project of planning 11 2x4s down by 6/32 (not all at once) I am not tripping almost constantly. The only other difference is that its summer now and the garage heats up pretty fast. Could it just be a cooling issue as well?

[@loveofthegrainworkshop2891]

Possibly as my shop is the same. But, once it starts tripping over and over. That means it’s gone bad. So just replace it. Saves loads of time and headache. Any other questions feel free to ask.

[@kenwoodruff3639]

I have purchased blades off Amazon and I replace them frequently. Where do you get good quality blades for your three blade Dewalt 13 inch planer

[@loveofthegrainworkshop2891]

After the 3 blades went bad. I replaced them with the Byrd Helical cutter head. So I unfortunately don’t buy those blades at all.

[@lorrainebayford177]

Load is the motor and line is main power coming in.

Thanks

The factory circuit breaker is a faulty design. Instead of just tripping at 19 amps, it is designed to heat up at the same rate as the motor and trip at theoretical overtemp. Thats why after the first trip, it trips every pass or two. The planer was completely useless to me, so I replaced the breaker with a non thermal 19 amp breaker. 45 minutes of planing 2x6's with no tripping. The motor was lukewarm to the touch. The factory should have built thermal protection into the motor, with overamp protection on the mini breaker.

[@loveofthegrainworkshop2891]

Great information. Let us know where we can get that breaker?

[@ltcg]

@@loveofthegrainworkshop2891 It was just a used breaker scavenged from junk equipment. I did however just mod a DW734 using a 20 amp breaker part # 4VA77 from Grainger. (for a friend) It might be a touch oversized, but my theory is that common sense operation > a scrap machine. In both our cases, the planers were going to be replaced because they were useless, so burning it up was no worse of a result. After repairing the DW734, I tested it with several small cherry boards, then a 12" x 8' rough cut pine. Taking 3/16" with 1/2 turn passes left the motor just slightly warm to the touch. Far cooler than a shop vac or any other universal motor after running for that length of time. TLDR. . . 4VA77 from Grainger, Mod at your own risk, and use common sense.

[@CloudfeatherRusticWorks]

@@ltcg Was looking at this mod for my DW735. The Grainger breaker is thermal as well.. Would this not have the same issues as the factory or is the Grainger designed to only heat up when it actually hits 20amps? Thanks. :)

[@randylates3777]

Where can I get the non thermal 19amp breaker??
