- I took apart this DeWalt 12 inch 20v Max Battery operated Chainsaw because it doesn't work. Can I fix it? spoiler alert, it's broken.
I was expecting to see a blown capacitor, but I think it's just a poorly made saw and I may just buy the Milwaukee Fuel Cordless chainsaw instead.
Had the same issues, with two of them, and now going to return this last one. Was considering getting a third one, but after seeing some of these comments I'm thinking otherwise. Mine has had lots of hours on them, in a short period of about a month each, so I've used it a lot, and was super stoked with it. Pretty much had it with the trips to HD for this product.
I have the same 12" Dewalt saw. Similar thing happened to mine. Didn't have that much run time, and suddenly stopped working... Only mine shows ZERO signs of life. I've seen a few videos where people tear them down for repairs, and almost every video has a different culprit! These things are JUNK!!!
absolute garbage. DeWalt should recall every single one and rebrand them as Black and Decker
Same problem
I had the exact same problem, and I hoped you had a fix. Mine was 8 months after purchase. The nearest repair depot is far away, so I decided to send it to them for repair. I set up the repair ticket on line. They gave me a UPS shipping label. I removed the bar and sent body, bar, and chain separated so it would fit in a box. Days later I got an email that said a part they needed was on back order, and it would take at most a week to get it. As I write this, it sits next to me. The whole episode took 1-2 weeks, and it was completely free, shipping free too.
I don’t know what they did. Here’s what the packing paper says: “Service performed. Ground wire continuity. High pot 1000. High pot 2500. Leakage current check. Product tested.” When I removed it from the box (a box that a new saw comes it), I saw that it was spotless and looked brand new. I checked the serial number; it’s different.
I won’t be able to test it until next week as I’m leaving on a trip immediately. I wish I knew exactly what they did, but that would require more digging, probably with fruitless phone calls. If it fails again? I’ll send it back or repair. It’s free under warranty, so what the hell. I’m not tossing a $250 investment unless I have no choice.
Without being there, I'd look at the batteries, or more likely, an overload condition that trips a resettable fuse. It works, something overloads the fuse and the fuse takes a while to cool down and reset itself. Maybe there's bush crap wrapped around the shaft? That little capacitor is probably for noise reduction. The motor looks like a brushed D.C. motor with the two wires.
thanks for all this! batteries are for sure good. there isn't a rest switch anywhere. they had been sitting for hours when I started making this video, one actually sat for a couple of days...so def not heat. the saw says brushless DC motor, I'm not an electronics guy...I appreciate the ideas, keep them coming
Same thing happened to me what I did is I took apart the trigger switch, clean the contacts and it worked again. It's the contacts inside the trigger switch
not in this case. I only used it for 20 mins, same problem with both. after sitting for a day they started to work again. the problem is, they are made poorly and they are junk
Thanks for this video, and all the comments. I was gonna buy a dewalt 12" brushless chainsaw...but now i am reconsidering my options
don't get one... I've heard very good things about the Husqvarna. that's what I'm getting instead.
@@TheHowtoDad thanks for the info, Husqvarna is always reliable. I used a small gas one and it was great. Well made. Easy to start. And had sufficient power
@@marcellaobdrzalek8435 ya. I have a buddy who has had a Husqvarna 40v for 3 years and it's stood the test. good bye DeWalt
Only found this video because I bought the same saw. I was using it, it clunked and you could feel it clunk and it no longer works. Completely broken. I only used mine for maybe a total of a half hour. It never cut anything thicker than 3 inches
piece of absolute garbage!
I have the same issue and after watching your video I still have the same issue and 6 min of my life gone, wasted, that I’ll never get back.
That's a diode not a cap...
I'd look at the trigger switch, see if voltage going through it to the controller. Both have a 3yr warranty.... Let dewalt fix them?
agreed. this is a DeWalt problem
If you send it to Dewalt: most companies require you to pay for shipping both ways. I’d just as soon use that money to buy a quality eChainsaw.
i have the same problem. the only thing i did was put a flexvolt battery in and noticed a huge difference in power. but after i got my m18' fuel. i just gave up on them
ya, these are basically garbage. I'm going to try the Milwaukee saw
Did you just make a 6 minute video on how NOT to fix something? Can you also show us how to not make scrambled eggs and how not to fix a hole in our boat with tampons? Gimme my six minutes back!
nope, can't have your 6 mins back, or the minute it took you to make the comment either. also, the video doesn't say I fixed it...DA
There’s a replaceable relay in there it’s like a $.10 part that burns out
Possible that happened with my ryobi? Brand new stopped working couldn't get it to turn over after taking apart
Gave a part number or link? 😊
I think you should try a 3rd one and what are you? A doctor, nice donning of the gloves!
they were covered in chain oil
I wouldn’t try another Dewalt. Fool me once . . .
Discouraging. I've had my Dewalt for a few years now & always worked great. Then it started to " shimmy" or bounce around when cutting & stop. It finally just stopped working altogether.I hate to junk it & buy another but looks like my only option.
Mine worked whenever I needed it (about 2-3 hours per year) for about 4 years. Then last week it quit after 2 minutes of working fine. Press the trigger, it moves forward a link and stops. Does that a couple times, then backs up 1/4 inch a couple of times, then nothing. Battery is fine. Pretty disgusting excuse for a tool.
ya, piece of garbage
Got one of these for Christmas... I've a similar issue on a brand new one, I'm hoping it's just because the bstteries are freezing cold.
these are also brand new. I think the problem is that they are junk
Found the issue with mine... The brake was stuck on. I smacked the chain brake and it disengaged, all good now.
I wonder if your issue is as simple 🤔
See you did the same as me, and gently pulled the brake, this disengaged it enough for it to switch on, but then promptly shuts back down. Pulling it harder you feel a click, and boom. Works. 🤦♂️
@@Daryl... I'll take a look at that. kind of makes sense that could have been it.
@@Daryl... how good a saw would you say it is? I am debating getting the 12" version
@@Daryl... Dude good on you for this comment. I have no idea why I didn't think to pull it that hard. Even when I did for the first time after reading your comment, it sounded and felt like I broke it lol but you're right it works perfectly. When I looked up online why mine wasn't working I was like there's no way this many of these chainsaws don't work. Thanks again.
mine too an xmas gift and it failed in this same way almost immediately
I have the same saw brand new worked for about 30 minutes and stopped did not even empty its first battery. Piece of Junk. Major headache to send back to dewalt.
That looks like a one-way diode not a capacitor
@@normdickson2438 ok. that wasn't the issue anyway...the problem is it's a piece of junk
I'm done with dewalt also, its junk
mate u have no idea what ur on about. that is not a capacitor it is a diode!
ya...I'm not an electrician. but it's busted
It’s the safety switch, sells on Amazon 12 for 5 bucks
it's not the switch. tested it
Check the safety switch. This video here shows how to test it. I tore my 20v chainsaw down because it was doing the same thing. It turned out to be the safety switch. ua-cam.com/video/_hrBc3HXj04/v-deo.html&ab_channel=ApacheRanch
I tried that. wasn't the issue
@@TheHowtoDad Did you ever figure it out?
@@disillusioned070 not really. I let it sit for a while, then it started working again. may have been a seized brake?
@@TheHowtoDad Copy. Well at least its working again. Mine would start running and stall but I could immediately release the trigger and pull it again and it would start working and stay working as long as I applied good pressure to the trigger so when I went into the repair I already figured I was looking at a safety device or faulty trigger.
