My 4-month-old Hoover Flair exhibits an intermittent failure: after running for 30 minutes or so, the motor will no longer switch on. Toggling the switch all the way forward turns on the brush, which spins away merrily, but in both the middle ("bare floor") and forward ("carpet") position, no motor, and thus no suction.
As noted, this problem is intermittent and if I let the Flair sit for a few days, it seems to restore function, but only very briefly.
Could this be heat-related? Is there perhaps some sort of "cut-off" in the design which disables the motor if it seems to be running hot?
I should note that Hoover "support" did not respond at all to my email inquiry well over a week ago, so unless I
can get the Flair running reliably in fairly short order, back it will
go. I will then shop for a product whose manufacturer actually supports
There's a thermal cut-off when the unit has overheated. Mine does this quite often and I remedy it by emptying the canister and making sure the filter is clean, especially of lint and things that prevent good air flow.

Remove the small screws on the bottom of the powerhead. On some models there are 2 hidden beneath the rubber wheels in front. Just pop the wheels out with a flat blade screwdriver and remove those two as well. Remove the hood and you have access to the belt, motor and roller. Here's the correct belt: http://vacuummedic.com/product.php?id=86
You have lost air flow due to blockage. Look for blockage in the throat of the machine where dirt enters from the floor. Do this by removing the base plate or opening throat inspection flap if so equipped. Also detach the hose and drop a coin through to see if there is and obstruction in that area.
there is a belt in the nozzle that is driven by a small motor in turn will drive the roller when set to carpet. did you completely dis-assemble the nozzle? ie, to remove the roller and clean the endcaps? this would also show the belt. The gear on the motor wears very easily and could also be worn. I would change the nozzle or get a new Flair. new nozzles cost about $25-$30.
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.
ALTHOUGH MOST FILTERS SAY WASHABLE THEY DO STILL NEED TO BE REPLACE AS WASHING THEM SHRINKS THE FILTER AND EVENTUALLY CLOSES THE AIRWAYS. WHICH ALSO IF NOT REPLACE WILL OVER HEAT MOTOR IN MACHINE AND CAUSE MOTOR FAILURE.
