Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum

1 Answer

No suction My Hoover Wind Tunnel vacuum runs but there is no suction. The last two or three times I used it, it shut itself off after having a burning smell. When I unplug it for the suggested 30 minutes, the motor will run again but no suction. What is wrong?? Should I just buy a nve one? This one is 8 years old.

    I took it apart and it was clogged up inside. After cleaning it out and putting it back together, it works fine! This is a bagless model and it still works as good as the day I bought it now that it is cleaned out!



    Thanks so much for your help!



    ps: The vacuum I had before this one lasted 25 years! It was a Sears Kenmore canister type. I could no longer get parts (the hose was full of holes and almost completely covered with duct tape) so I bought the Hoover. I guess I am just lucky or maybe I jut don't vacuum often enough???

Sounds like your motor bearings are going bad. This is generally indicated by the motor overheating, and the heat transferring out through the motor pulley, which is where the belt attaches. So, your machine is overheating, melting the belt, and then tripping the thermal cutout. When it cools and you restart it, the belt is no longer functioning due to being melted, and this would make it not pick up on carpet. If you look at the motor pulley and it is turning blue: this is indicative of overheating.
The other possibility is that there is a clog, which is also causing your motor to overheat; so before you throw it away make sure all of your air pathways are clear.
The fact that you've had it 8 years is somewhat remarkable, however, since most vacuums of this type are averaging a 3-5 year lifespan. (And half that for bagless.)
So, check for clogs, and if it's not clogged, you're probably due for a new machine.

Hoover Wind Tunnel does not turn on


that is a pretty good lifespan for a hoover, but its probably the power switch that's bad. Hoover uses a very poor quality switch. It shouldn't cost to much to have it replaced

No suction on Hoover Wind Tunnel.


Greetings from GoVacuum.com,

First this is a common problem on ALL bagless vacuum cleaners. Usually it takes longer then 1 day however.

Is there no suction in the suction hose, or is it not suctioning from the floor?

Most people buy a bagless vacuum once, then return to a bagged one after their bad experience, you are not alone!

Please give me the model number to your Hoover, (found on the bottom or the back of the vacuum on a foil label).

Thanks,

Hoover wind tunnel


Did you check down by the brush roll for a clog in the dirt inlet. And is the brush roll turning freely, if it is being lugged down, it can cause the motor to overheat and the thermo protector will caught it off, until the motor cools down. But if both are ok, then maybe the motor protector needs to replaced, it is prematurely tripping.

Hoover wind tunnel vacuum cleaner shuts off during use


Check the inlet down by the brush roll to make sure it isn't clogged. If not and the hose isn't clogged, then probably the thermo protector (part #28382093) maybe bad. It is mounted near the motor. Could be motor Part #43576188. But I would suspect a clog in the inlet or hose, or the thermo protector has gone bad.

Do you have suction at the hose end, if you do then it may be clogged at the inlet by the brush roll. Is the filter cartridge clean? If it is clogged and air can't pass thru it, then you will have no or low suction. Might also check the belt to make sure it is turning.
