I have gone ahead and taken pictures of how to change the cord on a Dyson DC07 upright. Here's what you'll need to have handy in order to complete this repair:
- T15 Torx
Bit Screw Driver
- Dyson DC07 Power Cord For All DC07 Models, Part 905449.
- A 2mm or Smaller Flat Head Screwdriver (width of the tip)
- Needle Nose Plyers
- Patience (haha)
The cord above is actually a link back to our site if you have yet to purchase your cord. We carry most every Dyson part.
IMPORTANT: MAKE SURE YOUR VACUUM CLEANER IS UNPLUGGED BEFORE DOING ANYTHING ELSE!
Step 1. First thing you'll want to do is to unwrap the cord from the machine, and remove the handle from the upright part, then slide the hose all the way down the wand, and remove the hose from the handle assembly completely and set it aside. Also remove the dust bin assembly completely from the machine as well.
Step 2. Once you've remove the handle from the machine I find it easier to work on if you lay vacuum on it's back, with the switch button facing upwards. Now remove the T15 Torx
bit screw that is directly below the switch actuator. I have circled the location of this screw
in the picture below:
Step 3: After you have taken off the screw, you're doing to need to remove the switch box housing from the vacuum that the screw was securing. Simply use your flat head screw driver, and pry the two small arms upwards. Be careful when prying, the plastic components on Dyson vacuums are really cheap quality plastic, and I can't tell you how many times I have seen these plastic parts break. Here's a picture of the location of where you should pry the switching off:
Here's what the vacuum should look like after the switch housing has been removed:
Step 4. Use your needle nose plyers to remove the terminals from both of the switch poles. Also be careful when removing these terminals, don't force it or it will break the pole right off of the switch, and you'll then have to replace the switch along with the cord. Also you'll need to remove the two white wires that are connected together apart, also using your needle nose plyers.
Step 5. After you've removed the two terminals connected to the switch, as well as the two white wires that were connected, follow the electrical cord up until the point that it enters the vacuum cleaner to the rubber cord protector. Lift straight up on this cord protecter to remove it from the vacuum.
Step 6. You'll have to now slide the cord out through the cord protector so that you may install the protector on your new cord. Unfortunately as you'll see, your new cord does not come with the plastic terminal protectors that are on the end of the wires, so you'll need to take off these plastic ends on both the black, and the white wires that come from the cord. The other wire that you see in there that has a white wire with no plastic cover, and a black wire that does have the plastic terminal. There's no need to remove the plastic terminal from the wire that runs down into your motor, just leave these alone. If you look closely at these plastic terminal covers, you'll see that one side of them have two little ridges on the inside, also that the bottom is flat, and the top rises upwards on one end. To remove these plastic parts, use your 2mm flat head screwdriver and insert it through the top part that has the two ridges on the indside. While your screw driver is in as far as it will go, lift upwards away from the wire while pulling out the wire at the same time. Repeat this on the other wire as well.
This is how the wires look like without the terminals:
Step 7. After remove the plastic terminal covers from the wires, pull the cord through the rubber cord protector and remove your old cord. Open your new cord, and now you'll have to feed the two wires through the cord protector. Simply push the cord through the ribbed end of the cord protector. You normally can push the cord hard enough so that the ends of the wires will come out the other end fairly easy. If the wires don't come out, use your needle nose plyers to pull the metal ends of the wires through the rubber cord protector.
Step 8. Reconnect the wires to the switch, as well as connecting the two white wires together. Here's how the wiring should look like when done properly:
Step 9. After reconnecting the wires to the switch, and to the other white wire, you'll need to put the switch back in place, along with the cords, and the cord proector. You can see little channels that the cords actually sit in to keep them from pulling out. Place both the wire on the bottom that goes to the motor, as well as the electrical cord into these channels. The two white wires that are connected together go to the left of the switch. Here's how it should look like when you're finished:
Simply put the switch housing cover back over the switch and cords, and screw the Torx bit back in, and then test the vacuum to make sure that the cord works.
