Question: Too Hot

1xmikex1

I was running my 4000 with a cutting wheel and it got hot, like a faint smell of cooking insulation hot. I let it cool off and when I started it back up the speed was irregular, it ran rough and had no power.... Armature?
WJA
Hello 1xmikex1,

If your armature smells like burnt insulation, or the windings are dark and loose. It sounds like you did fry it.

-WJA
Today I started it up and it ran fine up to about 15krpm where it started to get rough/vibrate. I was able to finish cutting the glass tile to complete my bathroom remodel. I am still thinking maybe the armature. Any thoughts?
I don't know when you posted this because I see no date. I'm have a similar issue but I didn't think to notice any smells, but my dremel 4k when running speeds up and slows down runs rough. Do you ever get your dremel fixed? If so, what did you end up replacing?
Question: Not Turning On

1583855

I received my 4000 Dremel as a Christmas gift, it worked fine last night. We did get a freeze & now it wont turn on. Any advice would great. TIA
WJA
Hello TIA,

Since you have only had the tool for such a short time. I'm sure it's not a brush issue. It may be the part number 2610004636 Electronic Speed Switch that is defective. You may want to take it back from where it was purchased to see if you can get a refund or a new tool.

Question: Dremel 4000 Armature Insulation ...

dj90423

Towards the back end of the armature on my Dremel 4000, there is a spot about the size of a bb where the reddish colored insulation has been burned off, and I see a bright arcing there through the housing.
Is this something I can repair, or, do I need to buy a new armature?
WJA
Hello dj90423,

It does sound like your 2610004634 Armature has gone bad and needs to be replaced. You may also want to replace your 2610005646 Brush & Spring Set.

Question: Dremel 4000 Repair

1224171

Hello,

My sister borrowed my Dremel 4000 a month or so ago. When I tried to use it the other day it wouldn't come on. She told me that while using it the motor just stopped. I took it apart and nothing seems to be burnt or disconnected. Do you have any ideas what I can do to resolve the issue?

thanks,

Scott
Hi Scott,
Well without looking at it I could only go with what generally fails on that tool and that's the Electronic Speed Switch
Part Number: 2610004636.Hope that helps.Good luck.
Tinker
Hi Scott, I'm wondering if the Electronic Speed Switch Part Number: 2610004636 fixed your problem. I'm having the same problem.

Question: Speed Hunts

1197336

Hello 1197336,

Since the 2610004636 Electronic Speed Switch is the unit that controls the speed of the tool. I would suspect that it is the cause of your problem.

Question: Thread Size On End Of Armature

1184189

Hello 1184189,

As far as I can see the threads on the 261004634 armature are .28 (pitch) x 40 (threads per inch).

Hope this helps,
-WJA
