DeWalt DCD996 Drill Repair Update
HTML-код
- Опубликовано: 6 сен 2024
- In this follow up video the DeWalt DCD996 finds it way back on the bench.... This drill has gave up again on us here. I believe it is due to the fuse being a higher rating fuse than I originally thought and the minimized surface contact of the original re-soldered fuse may have been the issue. This drill had worked ok for around 6 months now, but it is time to crack it back open. I believe with most of the fuse manufactures out there using V marking for 30A fuse that this is most likely a 30A fuse here. I ordered some replacements from eBay due to shipping cost of ordering these by there self at somewhere like Dig-Key or Newark. I would absolutely trust these brands better for sure. I will have a link in the description for all three if needed. Hope you find this update helpful and thanks for watching!

Nice to see someone changing parts at this level. Keep it up!
This is the worst Dewalt drill ever made IMO. I've had 2 or 3 of them all total junk! Thanks for the vid!
Nice video man. Sometimes I wonder if some engineers designing this stuff are in fact 5 years olds pretending to be engineers. It is time for manufacturers to design and build stuff that can actually last. The planet and us buyers will appreciate.
So I suppose you could do better?
@@joerogers9372 Did I say I was an engineer? Are you happy to keep spending your money on stuff that doesn’t last?
@@joerogers9372 Tools designed and produced sixty, seventy years ago and beyond still work, or can be refurbished relatively easily. The man has a point.
I would expect that the tool would draw at least 20A under load. Your 30A fuse is probably a good choice.
The fuses used in manufacture have connections on the end sides, but insufficient connection area on the underside, so they don't seem suitable for surface mounting. The replacement fuse used in your second video had more pad on the underside.
Using your first very helpful video I fixed a DeWalt DCD996 found in a skip.
Awesome job. Thanks for your comment! 👍
Thank you I ordered 10 be here dec. 27 if you run in to a need for some let me know may God continue to bless you and your family
Awesome! God bless you and your family as well!
This helps a lot, I hv long way to learn. Thanks for sharing.
It could be engineering problem, but l am more inclined to be either faulty parts or manufacturing .Thanks for the look.
Nice vid mate I'm currently repairing a 2021 996 has a broken connection on the motor and half the gearbox is missing, should have one coming with a dead controller going to use the gearbox internals to fix the 2021 model
Thank you sir! Very helpful!
You should cover the board in epoxy resin to protect it against water moisture and vibrations. GOOD JOB!
I fully understand that epoxy potting is superior to vibration and moisture ingress, but I am a technician. So my way of looking at it is not just reliability, but also repairability! We know electrolytic caps and from time to time Mosfets or fuses will blow. The epoxy makes the boards throwaway really and man I can't stand that. I really like it when things are made to be easy to repair and man are we more of a throw away generation than ever. I do understand the thought in this case about the vibration though. I believe it is more of a heat dissipation issue but epoxy may be the answer if they keep having the same failure! Thanks for your kind comment! I appreciate it.
Awesome work my friend! 👍
In Poland i can buy only 25A DC32V 1206 Fuses, which i use on Dewalt controllers, and everything works fine under load ;)
I wish I had this video 3 years ago. Very nice work. If possible can you post updated links for ebay? What are the chances this will work on a DCB999? Thanks again
Can you do an electronic circuit board repair on Milwaukee 2653-20 M18 Impact drive? You are a master on electronic with all the tools and knowledge. Milwaukee sells the replacement parts for about $120
If I come across one I sure will. I really enjoy working on tools and love learning more about them, I only do this as a hobby so I don't come across alot of tools, but I sure will look at it if I find one. Thanks so much for your comment!
Thanks I have 4 of them I’m fixing I already done 2
This broken non working brushless drill is my 2nd unit, tried comparing any difference from the 1st working unit but none that I can see....please reply for Help...
Hi,
I don't know enough about the brand to be of much help. I am sure you have tried more than one pack in the bad drill? Making sure the pack is not dropping out...
Hi sir, i have a new china made, Nanwei Brushless drill, was just working lastnight then morning upon checking to prepare for use...Power indicator still lights up, brushless motor kicks in for a second and nothing works...Any Advise to check on my drill?
I also have a DCD996 and what went wrong with this one is the whole gear assembly. Several gears ⚙️ are just broken and so far I can't manage to find them anywhere to purchase 🤷🏻♂️
I have seen a few on eBay from time to time. I also see AliExpress sells the gearbox parts for the DCD996 around $20. I don't know how well they are made though?
@@ThriftyToolShed oh, cool. Thank you very much for the tip!
Are any of these model DCD985? I have owned my DCD985 since brand new in mid-2012. Only used as a homeowner, not a contractor. For awhile now, maybe a couple of years (I don't use it everyday) it seemed as though the drill was not getting full-power. I attributed this to failing batteries as the original Dewalt batteries weren't holding charge for very long as of last year when I stopped using them they were about 9 years old. So I purchased brand new batteries which are very strong but the problem persists. I noticed that if I manipulate the trigger switch or squeeze really hard that I will once again get full power. So it seems like the switch is at fault or dirty. I understand I can purchase a replacement but most folks who replace them have NO operation of the drill at all. I'm wondering if it's worthwhile investigating or cleaning the switch if that is even possible? Or do you believe it to be simply worn out?
Hi, what do you use to remove the silicone junk? I'm so tired of digging it out of everyone I repair
Typically I just carefully dig it out even though it is a pain. Some silicone is a little more stubborn and sticky than others and I use some 99% IPA to help by saturating it and letting it sit for a little while. If it's still stubborn I will use my hot air station turned down to around 100⁰ to help while not getting the board too hot. I would rather just dig it out slowly if it's soft and easy as the EGO battery potting. It is a pain to get started but it's the type that lifts up in big chunks once you get it going. Some of the sticky silicone you just about have to use the Alcohol and a little bit of heat.
Smart man thanks for you from Iraq
i have my dcd996 drill and when i dropped it from a roof. It works fine but when I accelerate to the maximum its force is intermittent at the beginning and then it works fine.. it could be a disconnected cable.?? Or is it the fuses.
I would appreciate your answer.
thanks
It could be a bad connection on the board. It is not a blown fuse, but if the fuse is a bad connection it could possibly cause this.
clean the gears and grease them. thats all.
Thanks a lot
please can you tell me what the 2 wires going into the gear box are for
I mentioned in the first video on this repair that I thought it was a Torque or Clutch position sensor. This is an example of a similar one....
www.partswarehouse.com/DeWalt-Sa-Clutch-Position-Sensor-p/DWB-N174404.htm?Click=365719&gclid=CjwKCAjw6eWnBhAKEiwADpnw9smOXvP7jKMxrKgT-8YvuOqm9zKS0EzqZo1Li40Cki1Z8eaLzb_Z-RoCnQwQAvD_BwE
@@ThriftyToolShed Thank you so much for the reply. the new trigger i installed had no location to plug this into but the drill seems to be functioning correctly. im not to sure if the hammer function works since i haven't tested that yet. I hope it does. Do you know if rhere is anywhere on the board where i could posibly connect those 2 blk red wires?
Ok never mind the clutch does not work at all i guess its an "e clutch" that sucks
@@outblastt
Wow! So the clutch is not working at all it is just in drill mode all the time? Interesting. On this repair I remember running the drill itself while testing at one point and the clutch sensor wires were not connected. I never tried the clutch to see since the issue with this one was it was not running at all. I knew it was at least for feedback, but did not even realize it was full e-clutch.
So your going to need the exact speed control for yours unless they are similar enough and simply don't have the wires soldered on the board. That is why you were asking about that in the earlier comment. I have not run into that yet.
Can the fuses just be eliminated and jumped with solder?
As a final test to find what is causing the fuse to blow maybe?
I made this repair with a new 30amp fuse and it blew under a load.
Buen video dime se podrá poner el motor hacia un interruptor y directo a la batería sin pasar por esta tarjeta?? Saludos
No, this is a three phase brushless motor. It requires a controller board.
@@ThriftyToolShed thank You. Entonces supongo q habrá otras tarjeta mas pequeñas. 👋 Cómo la Router de 20v no veo una tarjeta tan grande gracias nuevamente por tomarse el tiempo en responder.
Thanks to your video on the ego chain saw I was taught to remove my first mosfet now I need one if you could help me with that thanks again for all your help
You need a Mosfet? I believe I shared a link in the video description and the latest EGO Blower repair may also help with some links to similar Mosfets unless they are out of stock? The newer video shows hot air use as well, it's much easier with hot air.
@@ThriftyToolShed you are right and thank you
@@betsyjames416
Sorry for the confusion. I thought you were asking about the Mosfets I used in the EGO blower or chainsaw. The DeWalt I am not sure which type they have as I have not taken one out yet.
Excelente video 👍👍tengo una sierra circular dcs 570 dewalt y no funciona prende su luz por un segundo y un silbido corto cada vez que aprieto el gatillo pero no funciona crees que pueda ser los fusibles al parecer todas las herramientas inalámbrica brushless funciona así o que cree UD que podría ser saludos desde Perú 👋
Hi,
Thanks for your comment. I don't know about that tool for sure. I have not worked on that model. I believe it is brushed so I doubt it's a fuse if it does make a sound when trying to start up. I would make sure the blade turns free and not locked down and then make sure the motor brushes are in good shape. most likely not replaceable brushes though. Sounds like the motor controller is trying to output? Best of luck to ya!
@@ThriftyToolShed es motor brushless igual que el taladro ambas dewalt que por eso digo su parecido. Gracias igual a UD dónde podré buscar información detallada de su tarjeta de control del motor saludos sigua los exitos
I have shared the only video I have on these. That is the only DeWalt Brushless that I have worked on. I share as we learn together.
i have the same unit as this. my problem is that it if you press the trigger it will start and then turn off immediately. after few presses it wont start. i suspect that its the clutch sensor. Any idea how to check the sensor if its not working? Thank you
It's been a while, but I believe I unplugged the sensor when testing the one that belonged to my friend. I am pretty sure with the clutch sensor unplugged the drill itself still ran fine. The clutch feedback was obviously going to be an issue of some kind. I am thinking the motor itself ran fine. I would be more inclined to lean towards the speed control part. First make sure the hall sensor connector on the back of the motor is connected well.
Hi again got those mosfets in not much success soldering them in do you have any tips soldering small mosfets like those
I have never replaced the ones on this exact board before, but I do have many repair videos. I have a couple examples below sharing how I repair similar boards. One shows using low melt temp. solder to help remove a connector and it will help with larger devices and I also will share one repairing a EGO blower using the hot air to remove and replace a similar style Mosfet. Hot air is very helpful with the Mosfets.

ruclips.net/video/FxO7CpV4b9g/видео.html
Do you have a video on removing one of those mosfets where the motor phase goes don’t mean to tie you up with questions but if you have time would be much appreciated
Sorry I don't, I have removed Mosfets on many other repairs. I have a recent EGO blower repair and an older EGO chainsaw repair that I replaced the Mosfets on video. I have not done one of these on the DeWalt as of yet. The 2 issues I had seem to be fuse related. It does seem a lot of heat would be needed to desolder those Mosfets. I would use low melt solder to help for sure.
Question, I would like to know what is d liquid u put before soldering?
I use flux when soldering. The RA rosin flux works well and is cheap. My favorite flux is Amtech 559 in the syringe, but it is a bit more expensive.

Great repair vid! What was the original issue? I have a dcd998 that only clicks and the LED turns on when I pull the trigger.
I believe the light came on but drill would not rotate. I shared back in first video.
@@ThriftyToolShed I appreciate the reply! Mine is brand new, I was just wondering if there was a fix for it.
@@mwpahl38send it in for warranty repair.
Well, crap. I just bought a 998 as well. We’ll see how it goes…
I found 2 number groups for the mosfets I need they are 4931N and R 1508 on the top of mosfet digikeys had no stock and I have not been able to find online can you help me source 3 of these or a replacement thank you
These Mosfets are getting very hard to get. I use similar ones on the EGO blowers, but higher voltage and lower current.
It takes some homework to try to switch over to some that may work. I have spent hours on Digi-key, Mouser, or Allied to cross over at times. I did find some of the 4931N on Aliexpress? Its not ideal, but its all I see available at the moment. its either that, take time to wait on some possibly on Ebay or spend much time crossing over to similar chip type that may have different rating that may still work. Best of luck to you!

Master, can those sensors be bypassed or not?
I had ask questions on the tear down video about the things just to the left of that fuse there are 3 of them they look like that fuse but are brown in the middle they have 18+ volts on one side but o volts on the other end I started to bridge them out with a clip and got a pretty good spark any ideas what might be, shorted if anything thank you for what u do
As mentioned, I have not worked on that exact one to say for sure. It's hard to say from comments. Your description of white with brown spot in middle did seem like it could be a fuse that had gotten hot, on the other hand it could be a light brown capacitor going across positive and ground and you would not want to short that out. It's way too hard to help diagnose from comments on a board I have not actually worked on myself. Best of luck to ya!
Thank you have a good evening the ones are less than 1/4 inch from where you soldered the fuse on in the video but I understand u can’t know what I am seeing thanks again
Ok, if it's just like the one in the video then those 3 light brown SMD devices are indeed ceramic capacitors and are most likely bypass caps so usually go from positive to a negative and should not be continuity across them. Hope it helps!
Thanks again sorry to keep bugging you I do thank you
Do you do repairs for the public???
I don't. I do not have a repair business at this time. Thanks for your comment!
🐻👍
Would you repair 2 if I sent them to yiu
I wish I had time, I do get asked this often. I do not have a repair service at this time. I work full time+ in a Industrial job and try to have time to edit videos to post. I try to help by posting what I have learned and sharing that best I can. Best of luck to you with yours!
So just throw mines away!
Can you tell me what solder and flux you use . Thanks
Hi,
I use many kinds really. I use the following the most. The Amtech Flux is great for board soldering especially smaller items. The RA Flux is same flux in the solder core and works great for tinning wires and larger solder jobs and it's less expensive by volume. The solder I use is leaded 63/37 and I actually have several sizes from .020 to .062.
The low melt solder is great for de-soldering only, but is a life saver de-soldering large power components and connectors that can't take a lot of heat when removing. Northridge Fix has many of these items for sale on there website and they work excellent, I will put some recommended links below as well if you find them helpful.

Hey I had this drill and it ended up taking a crap on me literally just quit right in the middle of a job out in the middle of BFE. I was cussing like a sailor! So I ended up getting a replacement and kept the drill that failed. 2 1/2 years later the replacement took a crap so I watched your video and both drills are back to work! Same exact thing happened to both of them! If you didn't post this video I would've had to buy a third one. Thanks for sharing your knowledge and know how. I'm pretty handy at fixing things and I'm glad I now have 2 working drills! Thanks again!
