    The blue wire has a seat below the brushing casing of the Dremel bottom assembly (you can see a little notch). Thus place the blue wire before putting back the stator…

    Thanks for the guide… It's crazy how many people's dremels are breaking…. Even more crazy, just like mine, they have had very minimal use… It's a shame really, I thought I was buying the best… Obvs Not !!

One of the brush holders has a component...small capacitor... ten cent part. If somebody can identify the value of the component, I could fix mine now that I've replaced the control board and still won't start. I shorted across the component and suddenly came to life.

Anyone with info about the third wire (on mine is blue ending with a small copper clip) serves? This is connected off of the switch, labeled W5 on the circuit board. [Edit. It is a ground] I suspect it is a feed back wire for speed sensor? But where does it attach? Some wear on the abovementioned capacitor crossing one of the brushes. Anny ideas?

You see the copper bushing slot at the top of the picture (next to the guy’s index finger) from step 9? Directly underneath it where the slot sits, there’s a tiny notch in the gray frame. Once you pull off the bushing slot from the frame (if you haven’t already), slide the small copper clip (from your 3rd blue wire) onto that notch. Then you push the bushing slot back onto the frame where it was. Essentially, the copper clip is “grounded” to that bushing slot.

I have a dremel 4300 that shot out today. Opened the baby up and one whole IC on the variable speed controller has been blown. Parts seem hard to come by for the 4300. Is it okay if I use the Electronic assembly for the 4000?

Hi I am looking to replace the same as well. Did you manage to complete your repair/replacement? Was it a 120V or 220V part?

Jem Q -

not so easy to place that blue wire!!!

Chrissy Michelle Strawn - Yanıt

Yeah, that blue wire is a complete pain.

Waiting for a replacement Armature and then the replacement fun begins.

is this part compatible with Dremmel 4300 model?

racasmjr - Yanıt

Hi. I just purchased a Dremel 4300 from America. I had to get an UK/IRL adapter to plug it in. I ran it on slow for under a minute and then POP & Flash. Now its completely dead - only a few hours old and only ran for less than a minute.

What would anyone recommend I do?

1, Contact the seller and send it back for repair (which will cost me extra for shipping etc)?

2, Try and fix it myself?

3, Replace the whole cord with my old Dremel cord?

Any help is greatly appreciated.

Thanks in advance.

i have a dremel 4000 an the big resistor near the black power cable got grilled, can someone tell me the value of this?

Tobias Kern - Yanıt

I’ve got a Dremel 4000 and have replaced the electrical assembly. Except for the blue wire, it’s reconnected correctly; and I think the blue wire is connected OK. Now ready to re-assemble. Is there a trick to re-assembly? And don’t tell me to follow the instructions in reverse order. It’s close to being re-assembled, but it seems nearly impossible to get all the pieces in exactly the right position.

On my Dremel 4000 (220V) one of the passivated rectifier CS1M (the one with label D5) exploded. Looking at pictures of the electronic assembly I could guess that it’s the same rectifier as the 2 others D1 and D6.

Would this passivated rectifier CS1M be replaceable by a general purpose one such as 1N4007 ?
