Lo desarmaría para ver si el condensador está quemado como el del video.
Afirmativo era también en condensador mucha gracias!!!!
The oh yes at the end is my honest reaction to any house fix as well. Good video!
Great video. I think I have a couple of lithium battery chargers so this came in very handy just in case. You did a great job of showing how to diagnose and fix the charger. Good job.
Thanks for posting this!!! My Dewalt charger was having the exact same problem. Opened it up and found one of the capacitor leads had not been soldered in properly and had come loose. I re-soldered it and it works perfectly now! Thanks for saving me some $$$!
Hello. Our conservation volunteer group had two of these chargers with the same fault. Your video has saved us about £100 on replacing them. Many thanks!!
Glad it helped
Thanks brother!!! You saved me a 60 minute round trip ride and prolly $50 or more... so simple and took less than 10 minutes. Thanks again!! John, A1
Perfect. I had a charger quit on me, and I suspect the same issue. I'll get back with you when I get it repaired. Thank you for showing me how.
Great Video, I had the same problem with the charger,but thanks to this Video i was able to reapair it. Thank you!
Glad I found this video! I'm not going to the trouble to repair mince since I just bought it in November. Taking it back to Lowes.
Gracias por su valioso video. Ademas quisiera preguntarle si es factible reemplazar ese capacitor por uno Low ESR o habria problema?
Thank you sir. You explained it very well and your demonstration gets five stars from me.
Excelente video! Me sirvió para reparar el cargador que tenía el mismo problema. Muchas gracias !!
Very excellent repair. Thank you much!
Freakin Brilliant.Such a simple fix that most would skip and just throw away and then shell out like 80 bucks for a fancy new charger.I have seen plenty of bulging caps on motherboards that still worked fine,so I dont think I would have thought of that.Since it was the only thing that looked off,great call on replacing that part.
We live in a throw it away world. Before I throw away anything I usually take it apart or see if I can fix it. You sound the same.
I’ve just repaired my dead charger. Having worked in the electronics industry for 40 years, I found that 2 diodes on the bridge rectifier had gone short circuit and blown the input 2A fuse. I requested some diodes from a mate at my ex work place,1N4007 and replaced. These have a good reverse voltage breakdown 700V. I replaced the input fuse with a direct short as the mains fuse plug is rated at 3A so that will protect the circuit. I suspect a surge on the mains supply caused the problem. I’ve recharged both batteries and my drill is now up and running.
hello, please know what transformer to use to replace the NF1? Thanks
fantastique description - I was able to fix my charger - thanks Ryan
Thanks a bunch. Same problem, same reason, same solution. Took mine apart, same bulged capacitor. Great video, Sir.
Awesome!
I am a repairman. That is very common with any power supply. Good vid.
Thanks for sharing! Great job. Wondering if a little higher spec voltage and quality like Nichicon, Panasonic, etc. would help too also.
Thanks man I have the same charger with the same problem
Appreciate your work bud! 👍🏼
Great video. Had same problem, capacitor was $6 on Amazon though, but 20 min fix and works like new. End of the capacitor was extruded and appeared like it had expanded 1-2mm. So I soldered in a new one and, just as this video shows, it worked like a charm. Thanks!
I’m having trouble finding the capacitor on Amazon. Followed the link and says product unavailable. Any suggestions on where to find the correct one? I’m unsure of exactly what to look for.

@@allen1473 Open your charger up, make sure you see 68 and 200V, in case your model uses different capacitor. I don't want to order from China, so I bought the one in the link below and received in 2 days locally. Make sure solder iron gets hot to remove the old solder, I used solder wick to suck up the old solder, slightly applied tension to old capacitor so the moment solder melted, the leg pulled out. 20 min fix!, and my old capacitor had a slight bulge, so moment I changed it, I was back to normal charging. Now run my charger on a power strip/surge protector.
If you are in DeWALT’s 20V Max system it’s hard not to end up with several of those DCB107 chargers. They only get away with charging so much for replacements because contractors make mistakes (leave them) and will overpay for an emergency charger to avoid holding up a job.
I, myself, have four DCB107 and one DCB118 fast charger. First one came with my brushless drill/driver set. Turns out my mom had already purchased a brushed drill with the same charger before moving in with me, bringing a second DCB107 into our garage. Next, I got a PowerDetect hammer drill to anchor into concrete which is how I ended up with my DCB118 fast charger. Finally, I bought an open box DeWALT mower that included two more of the DCB107 chargers for a total of four plus the fast charger.
I’m here because I’m considering mounting the extras into a TSTAK box so that the attached batteries don’t roll around and I’ll always have chargers when on the go.
My own got burnt this morning so it produces awful smell could it the the capacitor or the transformer though I haven't opened it yet
Loved your video and how you explained your self thanks
Great job on your repair video! Very informative and easy to follow.
Enjoyed watching this brilliant clip, well done for once an easy looking fix. 👍 🇬🇧
Hi Robert, I'm in Britain. Did this solve your problem?
Good video clear and easy explanation.
Thanks for the Video, it encouraged me to open up my charger and check for a swollen Cap but it was ok, So I looked around for another issue and found that under a diode was dark brown like from excessive heat (i think it was number 201 on the board) so I turned the board over and saw a cold soldered joint on the diode and re soldered it and Voila It worked!! Thanks Again
Thats awesome. Most would've thrown it away.
That's great. I wish I was that lucky. My 12v charger is fast blinking . I'm sure battery is fine.
Looked at board and can't see any visual issues.
Last week the charger worked one time, and battery was fully charged. But goes to fast blink again.
I have a craftsman v20 cmcb104, it has an aishi 2018 jpet capacitor in it. Can I use the same capacitor you listed in the video?
Hola, muy buena explicación estoy revisando uno. El dueño lo dejo cargando 2 semanas y ahora no prende ningun led con ninguna batería. En el capacitor hay 300V. Si tienes alguna sugerencia que podria revisar, desde ya te agradezco mucho. Gracias, saludos!
디월트 충전지가 좋기는 정말 좋네요
저번에 물에 닿았는데 번쩍 번쩍 탁탁 소리가 나면서 탔었는데 지금은 괜찮네요
Great video, very thorough. Thank you
Great video! I was legit so pumped when the moment of truth came, awesome!
Helpful, thanks for the video!
I just popped my charger open and suspected the capacitor as well, thank you for confirming my suspicions.
Everyone attempting this, REMEMBER TO SAFELY DISCHARGE THE CAPACITOR. I wasn't watching my hands when I yanked the PCB out and I zapped my dumb ass lol
🤣🤣
Thanks it’s was the perfect video to find we had a power surge and it did the Same thing to my charger
Mine had a tiny amount of paper out between the seams on the top
can you make any dewalt charger to work like DCB119 vehicle charger?
Very helpful video. Side note: one of our DeWalt chargers had a 100-micro-F (200v) capacitor and the other one had a 220-micro-F (200v) capacitor. So not every charger will have the 68-micro-F (200v) one shown here I guess. The 100-200v charger repair was successful, but our replacement of the capacitor on the 220-200V model failed.
Thanks for the information keep it up
Great video hope to fix mine same thing happened to me and de Walt in mexico doesn’t have a guaranty on accessories bad
Well done ! Kudos to ya.
Thanks for the video man
I have a hole blown through I guess it's called a resistor. Do you have a link for replacement part?
Great job. Imma gonna try this.
Well done sir thank you …..you explained everything really well I appreciate it!!!!!
Glad it was helpful!
Dude, I've been having the exact same experiences -- this happened right around the time of one of our California Public Safety Power Shutoffs. I even went back to my old super-reliable DeWalt 18v drill.
I actually bought a couple of new 20v batteries and ordered a new charger. But now seeing this, I'll have to try this trick. Thanks and please keep up the great work. I'll let you know if it works.
Please do!
fine job. well done
Any idea what is wrong with mine? No lights when plugged in. No light when battery is attached either. Thanks
Wow thank you!
Im gona go ahead and try it with my charger. 3 batteries doing the same.
Great video! Thank you.
your gonna be in my dreams tonight bro !! much love !!!
Muy bien, muchas gracias me sirvió el tutorial, bendiciones.
Gracias por mirar, agradezco el comentario.
Can you do one about the hot and cold delay
Well done, good explainer.
Awesome video. Thanks for sharing
Thank you!
Hi. I have questions. Y my charger had. yellow light And also
How would you test to make sure its the capacitor. Ohm it or plug in and test volts ( my elec skills go as for as a light switch on and off LOL) when I plug in cord and put Batt to charge I get nothing no lights blinking and battery want charge.
If you have a good multimeter you can use it to check the capacitance.
ESR meter
I also experienced the same thing with the 18v battery charge, the problem is this charge can't provide current to the battery ... I don't know why
Thank you so much!
Since you had it open, it probably would have been a good idea to clean up J1 and J2 on the board as it looks like there is some corrosion. Looks to be on the main board as well as on the little board which contains the actual terminals the the battery contacts with (not as clear video so hard to be sure).
Thank you. I have a cheapish charger that is showing the 'hot/cold' fault so not charging. Although the capacitor appears okay it's surely worth replacing - they're so cheap and easy to do so, even if unsuccessful, I'll only lose a few pennies. Thanks again.
I’d the same charger but when I put my batteries to charge the light stays red like the battery has already charged. I’d only got this driller a couple of weeks and only used it three times. I dont know if to return it or call DeWalt for them to send me a new one. Does somebody have the same issue as me?
Great job pointing out Negative pole...
Can this charger pluged into 220volt can be fixed
Great video and thank you for sharing. I wonder how many Dewalt chargers have been "bought" after people getting stuck with no choice. Also, think these chargers are made to self-destruct overtime to ensure repeat sales...
I agree. Said the same thing!
Good job.....Electrolic Capacitors have a lifespan that can vary from as little as 1,000 hours to 10,000 hours...cheers
Ill check it out thanks!
Sabes que compre un taladro con su cargador y baterias mas el transformador,fue enchufarlo y colocar la bateria para ver si funcionaba y comenzo a salir humo, lo desenchufo y lo dejo un momento, al rato lo intento nuevamente con mucho miedo y ahora no tira humo y la luz queda parpadeando tal cual la tuya. Agradezco el video y voy a desarmarlo hoy mismo y ver si lo puedo reparar. Gracias
What is number type IC PWM Primer ??
Thanks 👌🏼
My man my man… thank you
Thanks
I have a charger dewalt.When I put the battery in my charger, the red led flashes as if it were charging, but hours pass and the battery does not charge, the led only keeps flashing.

good job sir...
Remind the light comes on the hot cold light part comes on but the battery won't charge and I've left it on overnight and it's still don't do it got any ideas
I have the fast charger model and the torx T15 bits are too small, and the next up, the T20 are too. Can't figure out how to remove the screws 😭
I had the same issue... remember it is a security Torx T15 and not regular T15. Torx security screws have a post in the center of the head that prevents a standard Torx driver (or a straight screwdriver) from being inserted. I was able to shear the center post using a tiny strong flat screw driver and then my regular T15 just had a snug fit.
Exactly as expected
Hello !
I'm from Brazil
can you help me
I have this model
The problem is: The red led is not burned out.
but it doesn't blink
the capacitor is not inflated
Hello, I have the same problem...Have you found a solution?????
Same
Great video
Great presantion t/y
4:00 Your J2 and J1 Pins look pretty oxidized and burnt as well not sure if that has caused any issues since this video?
They haven’t, however I will keep that in mind if anything happens again.
Ty ❤
Good night am here watching your video but it's on a dewalt i have a vonhuas charger i think it's not charging you any tips for me
Open it up. Never know till you take a look!
الله يبارك فيك ويسعدك
+++Very good - well explained and demonstrated.
Nice job
I have a similar issue, but my light just stays on saying the battery is charged but it's not charging. I tried another charger and it works fine. So something is wrong with the charger.
perfect
how to install fan for cooling dewalt charger ?
Very nice. Now how do you check a battery for issues?
Keep them coming
Nice great video
thanks a lot what about fet is bad ,anyhow we save a lot as money matters.
Excellent video Ryan.
I don't have this issue with a bad cap on my charger, but did have a cap fry on an audio device I own. (I used to do audio recording for a living) This audio board has about 75 small sized Tantalum caps on it and is not marked positive or negative for the cap leads that need to be replaced. As mentioned the cap fried (it's burnt) and can't be read for polarity. Do you know if there is a way to determine with a volt meter (or other method) to find out which lead goes where on the PCB so I can solder in a new cap. Thanks and great fix on your charger. Giving you a sub too.............

My charger is connected to 240v makes some noise does not work on 120v.
Si 110 a 200v?
Un fu@#$$%kin believable. Thanks man. Awesome Video.
Hi mine is new and it gets hot and makes a noise and change for 30 minutes and still on red
