You have to remove the motor cover, There I believe 5 screw, take off the light lens and remove the screw holding the light. It should then pull off. You say you have power to the Vac, but do you have power to the motor. There also is a thermo by the motor, sometimes they open up, then the motor won't run.

    I have the same question. I found two screws under the circuit panel, and three on the front of the cover (seen with the vacuum fully reclined and front facing up). Am I overlooking some screws?

Why is my hoover windtunnel vacuum cleaner shutting off?

Hi there! Sounds like the thermal protector is being activated. This is usually caused by a clog or a filter that needs to be cleaned or replaced. Follow the steps below to prevent the unit from shutting off.

1. Remove the hose completely.
2. Use a broom stick to gently loosen and clear hose of clogs.
3. Remove the bottom plate and brush-roll.
4. Use a wooden spoon or something similar to break up and remove any clogs from lower hose.
5. Check the primary filter behind the side grille. If it is dirty you may rinse it under running water and allow 24 hours to air dry outside the vacuum.
6. Remove the bag door. Clean the primary filter located on the vacuum under the bag. Rinse with water and allow 24 hours to air dry outside the vacuum. The primary and secondary filters should be replaced at least once a year.
7. Check that the bag is not full. If it is, replace the bag.

The vacuum will turn back on when it cools off. This can take up to an hour. Hope this was helpful!

Hoover windtunnel self-propelled - will not turn on

You probably need the switch replaced. It's fairly simple to do youself, and it is a known problem with these vacuums.
You can order the switch from hoover for about $10

My vacuum died. It won't turn on. It is not the outlet. Is it a blown fuse? How do I replace the fuse? Where does it go? This vacuum is a little over 2 years old. My older Hoover WindTunnel STILL works and...

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.

Hoover U5468-900 WindTunnel Supreme suction is suddenly poor

The other possibility is there is a blockage in the foot. these models have dual channel air flow (windtunnel) and become blocked when not cleaned depending on use. under the roller there is a cavity that can be removed for cleaning. a hot motor can be caused by poor air flow.

Check that the bag is not full, check that is not a broken contact in one of the wires.

Hoover Recalls Self-Propelled Vacuum Cleaners
Consumer Complaints
Hoover Company Inc. has agreed to pay a $750,000 civil penalty to settle allegations that it failed to report to the U.S. Consumer Product Safety Commission (CPSC) the sale of vacuum cleaners with defective on-off switches that can overheat and cause the vacuum cleaner to catch fire.
In April 2005, Hoover conducted a recall of 636,000 Hoover Self-Propelled Upright Vacuum Cleaners because of defective on-off switches.
In June 2004, after CPSC received notice of several vacuum cleaner incidents, the Commission staff requested Hoover provide a full report of incident information. In July 2004, when Hoover submitted a full report, it had notice of 260 consumer incidents, of which 141 involved reports of fire. Additionally, there was one report of a minor burn injury.
Hoover first learned of a vacuum cleaner switch on one of these units overheating and melting in April 1999.
Federal law requires firms to report to CPSC immediately (within 24 hours) after obtaining information reasonably supporting the conclusion that a product contains a defect which could create a substantial risk of injury to the public, presents an unreasonable risk of serious injury or death, or violates a federal safety standard.
These Hoover Self-Propelled Upright Vacuum Cleaners are plastic, upright vacuums with the brand name �Hoover� and words "Self Propelled" printed on the front of the product.
Only those Hoover Self-Propelled Upright Vacuum Cleaners manufactured between May 1998 and November 1999 are included in the recall that is the subject of this penalty.

Off/on switch does not work

The on/off switch in Hoover Windtunnel upright vacuum cleaners is operated by a lever in the handle assembly.  remove the two screws on the back ovf the vacuum and see if the lever has bypassed the switch assembly.  if so, re-assembly should fix the problem.  It is also possible that the switch activating lever has broken.  If so, replace the activating lever.
