In this video we look inside the EGO 56V Blower and do some troubleshooting and Fault Finding (Circuit Testing). We could not get all the information needed for a quick repair but may still be able to order what we need for a future completion. We get to see the differences between the 14" chainsaw motor controller and the one that is in the blower and how its high current devices are less populated and we see the speed control is sensor-less while the saw had hall effect feedback. I also had to re-record some of the audio from the side bench view due to audio interference so it doesn't match or line up the same. At least the audio level is a lot better. Thanks for watching!

This is way over my head as well, I am just starting to enjoy this kind of repairs, you show us novices how to properly troubleshoot, so I'd rather watch and learn from you, I'm also beginning to understand how much patience is required for these tasks. so glad I subscribed.

I am in awe of your comfort level doing these repairs. Your walkthrough of your troubleshooting process is also very clear and concise. That being said, this is way over my head. I have a 56v EGO hedge trimmer that needs fixing. Could I pay you to fix it or can your recommend anyone? Thanks in advance.

Thank you for your kind comment. 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!

Great job on this video! I've got a LB5300 blower that just quit. I figured it was the driver circuit to the motor. A replacement for the board is available from an online parts supplier for about $100 !!! That 3 phase 50 volt controller ipissed suggested in a comment might work fine. Even though the battery is 56 volts, I bet that extra 6 volts isn't crucial. I'd try it on mine except I don't want to wait 2 months for it to arrive from China. I'll call EGO tomorrow and see if I can get them to send me a board.

I have a video showing the cheap 50V BLDC controller and then I did a video installing it into the blower as well. I have links in that video description. The have them on Amazon as well. The 50V capacitor I did replace with a 63V and of course we are over driving it so I always install it in the air flow. I have more detail on it as well in a video about making a EGO Vacuum. I used the controller in that as well. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kEb8gGwnoDY.html

I know this is well after the fact, but could you populate the four vacant Mosfet positions to adequately cover the current demands? I suppose there might be support circuitry, but I did not see any in the video. I enjoy your presentations, and though I have no professional training, I feel stimulated to perform my own repairs given your teaching. Thanks!

Hi, I don't believe it would work on this board since different sizes packs seem to have a different program. Just my thoughts on it, I know different generations of boards will differ slightly. Thanks for your comment!

My backpack blower just stopped working as well. This video is way over my head in terms of know how with little electronics. I bought from another owner so warranty will not go through. Am I $hit out of luck with it? Trying hard not to go get a gas one...

Question how to use just the blower motor alone direct from battery. Motor has blue yellow and red wire
@ThriftyToolShed
@ThriftyToolShed 3 года назад
You have to use a BLDC controller similar as shown here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-kEb8gGwnoDY.html

I wonder if those MOSFETs blow because of the battery getting disconnected while running
@ThriftyToolShed
@ThriftyToolShed 3 года назад
Possible, I really believe EGO had some bad Mosfets or at least a large batch of them. I realized that this was common failure but still out of 6 of 7 packs I have purchased only 1 has done that so far. I did of course buy several with similar issue from eBay but they were not my failures. Seems like a small percentage of many produced. I still am not sure, but I even replaced with exact Mosfet to see if it would fail again such as a bad design rating etc. But I have not lost any replacement mosfets either so far.

do you know where i can find that entire unit new or the part number for it im working on the same blower ?

I have not had any luck finding the ego controllers. I posted a video recently about using a small BLDC controller that is rated up to 50v and I am testing it out on a blower right now with small modifications and it is running the blower just fine. I also found a rare 72V controller that is still very small and less than $20USD as well. I will be posting this video in the next week or so if the test stays positive.

@Astro Mars I have a video showing a brushless controller running mine. I have had really good success with mine. I will do a update video soon. I have had luck with one original controller repair. I replaced the mosfets on one phase and blown fuse and it worked. It is just like the 14" chainsaw controller repair really. I only worked on 1 chainsaw and fixed it. I have worked on 3 blowers and only fixed one. I like the controller I replaced it with better anyway!

Hey I have the 650 blower and it just quit working, where are you located do you have any parts? Thanks
@ThriftyToolShed
@ThriftyToolShed 3 года назад
I do not have parts. I am in Georgia. I shared the BLDC driver that worked for me on my 480cfm. More output than my 530cfm for sure. It is still working well too. I will do a update video soon since it's still doing great!

I have just been working on stuff for 30 years and enjoy it. I am not smart. If I can do it, anyone else can as well. I see what you are saying about parts now. I thought you were asking if I had parts etc. Thanks for your comment!
