Having problems with your Hoover U5750-900 WindTunnel Bagless Upright Vacuum ?

Hoover U5750-900 just shuts off

\015 We have a Hoover U5750-900 Vacuum that works fine for 1 or 2 10'x10' rooms then just shuts off. We have a fairly low shag carpet. No pets. We need to wait approximately 30 minutes and the it works again. Runs for a short period and shuts off again. \015\012\015\012I'm guessing its not getting the proper air flow and has a automatic shut off. But i have taken it apart and cleaned the hoses, brush, filter, all with no difference.\015\012\015\012The other option is that it's over heating and has a automatic shut off. Given that I have taken it apart and cleaned it, I'm not sure what would be causing the over heating.\015\012\015\012Any suggestions would be appreciated. \015\012Thank you\015\012Mike\015

I have a similar bagless model U5757-900 that is shutting off. I disassembled the unit, and what I found is that the motor front bearing had accumulated enough grime so that the bearing locked up. When this happened, the bearing outer shell spun in the plastic housing, causing it to soften, from friction heat. This allowed the motor shaft to become off center from the normal, centered axis of rotation. Once this happened, the rotor inside the motor began to rub against the stator, the fixed part of the motor inside. This loaded down the motor, causing excessive current draw, which caused the overheat switch to activate, shutting down the machine.

In your case, it might not be as bad as in my case.

Remove the dual-cannister dirt cup.

To find out, disassemble the unit lower section: on bottom, remove 4 screws around the rotating brush housing. Remove the brush cover, then remove the brush, then remove the belt. Remove the wide plastic housing behind the brush. Remove the two screws, from the bottom, that retain the upper hood. Remove the hood.

On the back, remove the two screws and hose retainer going from the base to the upright section. This releases the hose from the lower section.

Now press the tilt release, and lay back the upright section. Remove the four screws, two on each side, from the trunnion caps, where the upright section tilts on the lower section. Remove the trunion caps. Remove the upright section from the lower section.

Remove the headlight cover (2 screws).

From the back, remove the single screw retaining the bezel above the headlight area.

Slide the bezel upwards and remove.

Remove the four screws that retain the motor cover clamshell. One is from front, and other 3 from rear.

Open motor clamshell halves to expose motor.

Note orientation/position of the three wires on the motor, and remove those wires. Lift motor out.

To open the motor, gently tap the edges of the impeller housing (aluminum shell) on the edge of the shell, in the little gaps around the shell.

Using a 1/2" socket, remove the nut in the center of the impeller. This is a LEFT HAND NUT. TURN RIGHT TO LOOSEN IT.

Gently wiggle the impeller while pulling until impeller comes off of motor shaft. Use a glove so the impeller doesn't cut your hand.

Remove the large flat washer on the motor shaft. Remove the small sleeve from the motor shaft.

On the brush end of the motor, using a small screwdriver, pry out on the brush holders. Set them aside.

Remove the two screws holding motor together. Seperate the motor front from motor rear. Withdraw the motor rotating part.

Look into the inside of the stator, inspecting for bright, shiny areas where the rotor may be dragging on the stator. If you see these, then the front bearing, in the plastic motor frount, is fried. I don't think Hoover sells this part alone. Also inspect the plastic front bearing retainer to see if there is any melting that has allowed the bearing to become off center.

In any case, if there is scrubbed out places inside the stator, then the motor requires replacement, about $70 for the motor... You might be able to find an entire new vac for less... or, like me, find one on the side of the street where someone has tossed out a unit.

You may luck out and find that the impeller unit is just filled with some trash so air cannot get to the motor for cooling... or you may have a shot motor.

My Hoover Windtunnel Ultra U6425-900 began shutting off after a few minutes of vacuuming. The time interval became shorter and shorter. If I leave it sit a while, it will start again. This does not happen when I used the attachments - only with the floor brushes. The switch has recently been replaced and the whole vacuum serviced by a Hoover dealer about a year ago. I have been told by a local repair shop(not a Hoover dealer) that it is the motor, there is nothing to do other than replace t

I have a hoover windtunnel upright vacuum, It will not shut off and I have to unplug it to do so. If I take apart the upper handle and manually flip the internal switch it works just fine, only when using the external switch on the handle, wont shut off.

This is a common problem with this machine. The switch has too much resistance to be turned on and off with the switch button and rod. If you put in a new switch, ( # 28161075 ), your problem should be fixed. ... Vacuums

On our Hoover U6445-900 (Mach 6.9) we replaced the small belt that goes to beater brushes in front of unit. Upon starting, the Hoover quickly got hot and smoky. We shut it off and looked things over carefully, but the second try also resulted in friction heat on the belt. Now it appears the belt may have stretched due to heat and the brushes won't spin. Any ideas?

Hoover S3765 I have a Hoover S3765 (serial # 040600024465) and the unit stops working for no apparent reason. The light on top of the unit goes off when it shuts down, so I don't believe it's a problem between the hose, the tube and the floor unit. Sometimes I have to let it sit for over one hour before it will come back on. I've tried different electrical plugs too. Still won't turn on. Any ideas or suggestions? Thanks
