Dyson DC04 Motor Replacement

Remember to have the appliance unplugged from the mains before attempting this repair.

Possible Symptoms of a Damaged Motor

The things to look out for are:

A strong smell of burning;

The motor may sound laboured;

The motor may make a low popping bubbling noise;

Smoke from motor casing area;

A high-pitched noise may indicate that the motor bearings are worn.

Tools Needed and Other Information

A new motor - but you knew that already didn't you? However, what you probably don't know is that there are two different types of motor fitted to DC04's. You can find a tutorial about that here: Replacing a Dyson DC04 Motor (Ametek or YDK).

You also need a T15 torx screwdriver. If you don't have one - you need one. You can get a new motor and the T15 Torx screwdriver you need >>here<<.

You also need a large flat blade screwdriver for the retaining screws on the soleplate.

The repair detailled on this page was carried out on a lime green and grey machine that has a single drive belt and no clutch. If your machine has a clutch, you will also need a belt removal tool. You can read all about those - how to use one and where to get one from here: How To Use The Dyson Belt Lifter Tool.
