Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum
How can I replace 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.

This has happened to me on at least two of my well used hoover windtunnels that I've owned. Easy fix: take the handle off and tightly wrap duct tape or electrical tape around the black plastic "switch rod". Doing that will make it thicker and thus able to activate the on/off switch again.

Tips for a great answer:
Nov 28, 2015 | Hoover Vacuums
1. Locate the primary filter behind the side grille. Wash the filter, squeeze it out and allow 24 hours to air dry outside of the vacuum. It should be washed about every other month.
2. Locate the secondary filter located in the vacuum base under the paper bag. The secondary filter can be washed in the same manner as the primary filter.
3. Replace the bag if it is full.
4. Remove the hose from both ends. Use a broom stick to gently loosen and clear any clogs from hose.
5. Remove the bottom plate and brush-roll. Use a wooden spoon or something similar to loosen and remove any clogs from the lower hose.
6. Check that the brushes are still spinning. If not, replace the belt.
Hope this helps!
