Power will not switch off. The switch will turn the vacuum on but when you are finished vacuuming, the control will not turn it off. I removed the handle and worked the red on and off switch by hand and there is nothing wrong with the physical switch. the problem is with the plastic depressor that slides over the switch. How do I fix it?

It sounds like there may be an issue with the power control system on your Miele C3 cat/dog vacuum. Here are some troubleshooting steps you can try:

1. Check the power control switch: Make sure that the power control switch is functioning properly and that it is able to move freely through all of the power settings. If the switch is stuck or damaged, it may be causing the vacuum to remain on the minimum power setting.
2. Check for debris in the power control system: Debris can sometimes accumulate in the power control system and cause it to malfunction. To check for debris, turn off the vacuum and unplug it from the electrical outlet. Locate the power control system and use a small brush or compressed air to carefully clean it.
3. Check for a clog in the hose or suction path: A clog in the hose or suction path can cause the vacuum to lose suction and remain on the minimum power setting. To check for a clog, remove the hose and use a flashlight to look for any blockages. If you find a clog, use a broom handle or similar object to carefully remove it.

If these troubleshooting steps do not resolve the issue, it is possible that there is a problem with the power control system or another internal component of the vacuum. In this case, it may be necessary to have the vacuum repaired or serviced by a professional.

You can change the switch.

It's highly probable that the Dyson power switch has gone bad.
You can buy dyson dc14 switch here.
The switch is located right behind the front covering of the neck or handle when you remove the telescopic wand. Please make sure that the vacuum is unplugged before you start this project.

the Oreck XL3640 power switch goes bad most vacuum service center can order a new switch it has 3 wires remove screws from handle to get at switch hook up wires to new switch color code of wires of wires are black white black just put on right terminal on switch

The machine needs a new switch. The switch is stuck to the "on" position.

Hello,

This is a clear indication that your on/off switch is probably gone bad. What happened is probably the handle latch was not properly installed when you replaced it. No worries though, I have written a clear, easy to follow guide on how to replace the on/off switch on your Hoover Windtunnel Self-Propelled upright.

What you'll need to do this repair:
- Phillips head screwdriver
- Needle Nose Pliers
- Hoover Windtunnel Switch For All Upright Models

Step 1. Turn the vacuum cleaner around so that the back is facing you. Remove the two screws at the top of the vacuum that are holding the handle on the machine. Please see the picture below of the two highlighted screws that need to be removed;


Step 2. After these two screws have been removed, simply slide the handle backwards, and remove it completely from the vacuum and set it aside. You now can see the on/off switch, but you can't easily change it from here, you'll need to complete several other steps before you can remove the switch. Here's what the vacuum should look like after removing the handle:



Step 3. After removing the handle from the vacuum, turn the machine around so the front of it is facing you. Open the vacuum bag door and set the door aside. Also remove any attachments that are on-board in the tool storage bin, this model has a hand-held turbo brush stored here. After removing both of these parts, you'll need to unscrew 3 screws that holds the tool caddy onto the vacuum cleaner. I have circled the area where these 3 screws are located:



Step 4. After removing these three screws, pull the tool caddy off of the vacuum by pulling straight forward by using the tool caddy lid. You'll now have access to both the front and the back sides of the switch. Use your needle nose pliers to remove the two wires that are attached to the switch. Be careful when pulling these wires off because if you pull too hard, then it will break the switch terminal off inside of the wire. Most models have the wire that has a plastic covering over the end of it on the top, and the metal terminal is connected on the bottom. The two lead wires that need to be removed are highlighted:




Step 5. After the wires have been removed from the switch, turn the vacuum back around so that the back of the machine is facing you. Simply use your flat head screwdriver to pry the switch off. You may push on the back side of the switch where the wires connect to it in order to give a space so that you can get a screw driver behind it. Here's how it should look:



Step 6. Once the old switch has been removed, simply push the new switch into the open hole. Important: Make sure that the Off setting of the switch is at the bottom, and the part of the switch that says on is on the top, otherwise the switch will be reversed. Re-attach the wires to the switch, with the wire that has the plastic covering on top, and the metal wire terminal on the bottom. The only tricky part of reassembling is when you put the handle assembly back on the vacuum. As you can see, there is a metal cable below the switch. This metal cable controls the self-propelled mechanism. If you look at the handle assembly, you'll see where the self propelled cable sits inside. The easiest way to line these up is to pull the cable up to the top, and then line up the rod inside of the handle that the cable goes in, and slide the handle back on the vacuum.

I hope this was helpful.

It sounds as though you have a bad switch.

It's probably the power switch. My switch was dicey for a couple years, finally gave out. Easy to replace.

Remove the two screws just above the WARNING on the rear of the upper handle assembly, then slide the whole assembly to the rear of the vacuum.

Remove the dust bag cover. You will see two holes just above the upper corners of the dust bag. Remove the screws from these recessed screw holes.

Open the furniture cleaner cover and remove the cleaner attachment. Remove the single screw that was hidden behind the attachment. Then remove the attachment housing by pulling it towards the front of the vacuum.

Inside you will see the rear of the power switch. Pull off the power wires (don't worry, easy on/off male/female connectors, no soldering).

The switch is held in by tension bars at the upper and lower rear of the switch. Firmly press down on one of both of the upper/lower tension bars, and push the switch through the housing from the rear of the switch.

Replacement part number is 28161067, about $2.50. Shop will charge about $85 to repair it themselves.
