Dyson DC04 Motor Burn Out
Original Message Oct 28, 2009 3:53 pm

Today my Dyson DC04 motor burnt out it is 7 years old exactly and its burnt out. Does anyone think this is good for a machine that is 7 years old? It was used heavily throught its life.

I have have a choice to either buy a new mtor which will cost me Ł25 from Dyson and fit the motor myself or spend Ł180 or so and but a new Dyson. I don't really like the newer Dyson and haven't got a lot of money to spend so don't mind buying a new motor and fitting it myself (I have had to strip the motor last year and put new ducting on the machine)

Its a shame as even though initially I didnt expect the Dyson to last this long I really didnt want it to go wrong at 7 years. Any people with similar expecrience of their Dysons burning out after 5 - 7 years?

Thanks for the responses guys.

I have taken my DC04 apart today, just to get the motor out so I can get the numbering out as I was told that Dyson used 3 different types of motors for the DC04. I'm assuming that they mean the Dyson Lime one which has no brush control, the Zorb and of course the standard brush control DC04 I have. I will order the motor when I come back Middle East end of next week.

Anyway, I took out the motor, turned the spindle and noticed a slight rattle. The fans are not rotating!!! I'm not sure what has happened here as the motor turns ok and so does the nut at the back of the fan bit but the fan doesn't. It seems that when the motor burnt out it made something break in the unit as the fan did not just decide to break 7 years later. The motor has a funny smell to it and 2 - 3 communtator bits look scorched.

I agree it has does good in 7 years. The belts look in good order too on the clutch so will keep the same clutch, just replace the motor and the post motor filter which is completely black.

Id like to post a link to my Youtube video showing the noise the Dyson DC04 does but not sure if I can here so just search Dyson DC04 Motor Burn Out in Youtube.

Hello Bucks03:

Thanks for the update Bucks03. Enjoy your trip to the Middle East! Good time to go.

Some questions: Are the commutator segments shriveled? Loose? Gaps between them that are larger than the gaps bewteen the good segments? How are the motor's carbon brushes? Should be chopped up and shriveled too if the commutator segments are bad. These problems would all result in the burnt smell of the motor.

Fan/bearing issues: Has the hole in the center of the fan widened over time so the fan nut no longer holds it firmly in place to turn with the armature? This may have caused the fan to freeze. But you should be able to move the fan with your hand.

Not sure what motor is used in the DC04, have never seen one and taken apart. Dyson's DC07 used a single fan panasonic motor with an excellent reputation for lasting more than 7 years in bagged vacuums.

BTW, all the possible problems you describe should have had tell tale signs/symptoms before the motor died.

You may want to take the motor along with you and ask the opinion of the pros who inspect it.
