Having problems with your Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum ?

Power switch will not turn off.

\015 The power switch will not turn off.The vacuum is self propelled and I guess it was picked up by the top of the handle too many times. The handle moves in and out to change the direction of the vacuum so its designed to move up and down. I assume that it has now misaligned the power switch so it come on immediately when plugged in and the power switch has no effect. I tried to take it off but after removing all of the screws I could see (1 in front, 2 in back), it would not come off. Its seems like a simple fix if I knew what to do. :-)\015

Greetings,

\015\012This is a relatively easy fix for you. What I've done for you is take pictures of this repair on your type of vacuum to make it as easy as possible. I will explain step by step what you need to do in order to fix the switch on your Hoover.
\015\012
\015\012What you'll need to do this repair:
\015\012- Phillips head screwdriver
\015\012- Needle Nose Plyers
\015\012- Hoover Windtunnel Switch
\015\012
\015\012Step 1. Turn the vacuum cleaner 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;
\015\012
\015\012
\015\012bbf0111.jpg\015\012
\015\012Step 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 may remove the switch. Here's what the vacuum should look like after removing the handle:
\015\012
\015\012
\015\012
\015\012721c0e8.jpg\015\012
\015\012Step 3. After removing the handle from the vacuum, turn the machine around so the front of it is facing you. Open the bag housing and set the bag 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:
\015\012
\015\012
\015\012071e740.jpg\015\012
\015\012Step 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 plyers 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:

\015\012
\015\012d5638fa.jpg\015\012
\015\012Step 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 front 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:
\015\012
\015\012
\015\012a01a9ad.jpg\015\012
\015\012Step 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 have a Eureka Upright vacuum (4800 Series). When I try to start it by turning the switch on, it wont. For few days, I was able to get around this problem by repeatedly turning the switch on and off until it turned on but that does not work any more. Could it be something related to the switch it self or the power cable. My wife mentioned that one of my kids might have pulled the power cable too hard (at the back of the vacuum). Any help to solve this problem will be very much appreciated. Tha


... Eureka Smartvac 4870 Bagged Upright Vacuum

Hoover Upright Vacuum model U5470-900 - The On/Off switch on the handle does not properly engage the power switch deeper in the handle assembly. It appears to ride over the lower switch and doesn't engage it to operate it. If I play with it, I can get it to maybe turn on the vacuum, but, then the upper handle switch won't turn it off. Our current workaround is to use the power cord for on/off operation.

Kenmore canister model 116.25513506 wont turn on. when handle switch is turned to floor. vac motor does not turn on. When switch is turned to carpet, floor nozzle works but vac motor does not. I checked fuse, all o.k. checked continuity for plug, o.k. removed wires for bag full switch...motor wont run. I wired motor directly power cord...motor runs.

Electrolux Epic 6500 SR ...no power to power nozzle. I think it is the switch in the handle because if I use my friend's hose/handle (same model), my power nozzle works fine when I turn on the switch. If you think it is the switch, can I get a part for it?


That's about the best one to narrow down a problem, however, there could also be a break in your hose wiring. Switches, hoses, and hose handle assemblies are all available at your local Aerus Electrolux store. Simply take your entire machine in so ... Vacuums

I had the vacuum cleaner question about the canister and the wand/powerhead... the Kenmore Progressive Vacuum canister model 116.25812 and the canister not powering off without unplugging the vacuum. The solution I received that they both run on their own switch so it is normal makes sense. However, is there a power switch on the canister anywhere? The only way for the canister to be turned off is by unplugging it. Any ideas? One would think there would be a switch. I am new to fixya and hope

Power nozzle on E-series won't start when cold unless the red 'reset' button is pressed multiple times while also holding the trigger to 'warm it up'...this is w/the power nozzle off the floor - no restriction on it turning. Once it's been running and then turned off the button must be pressed w/the trigger to get it to run - again w/the nozzle off the floor. It also seems to shut off too easily while vacuuming. I replaced the motor,which didn't fix it. Is the reset switch next on my list? T

It won't turn on. I have partially disassembled it and have continuity between the power cord (wide blade) and one of the connectors where the switch assembly snaps in. Also, switch is working fine. There is continuity across it, then no continuity across its connectors when the switch is pressed. Not sure what to try next.
