Question about Hoover U6437-900 / U6439-900 Windtunnel Bagged Upright Vacuum
My Hoover Windtunnel shuts off after 2 minutes of use. I have replaced the bag and filter but it still shuts off.
I found the following solution on this website. I have searched for hours and finally found this solution, it works! I HAD the same problem after cleaning the filter mentioned below, it is now working like it was new.
yes this machine has a thermal protector in it to shut off the machine if it gets to hot, this is normal. if there is no clogs in the hoses or in the machine then you will need to wash the filter at the top of the machine. you will have to remove the dirt cup and at the top you should see a half moon orange, well inside of this piece is the washable filter, clean and let it dry completly before putting back into machine. if this gets dirty and has not been cleaned, you can lose alot of suction. in some cases if this filter is not cleaned it can cause the machine to overheat so bad that it can damage the motor.

I had same problem. Turned out to be the filter that sits above the waste cannister. Remove the waste cannister. There is a little orange lever that releases the filter. It was caked with dirt not allowing any air flow causing the motor to overheat.
This foam filter gets dirty pretty fast.

The thermal protector gets messed up if it has to trip too many times, and can start tripping as soon as it barely warms up. I had to bypass my thermal protector and just go over it very completely to make sure theres no clogs or dirty filters often, as it costs $50+ to have the $80 vaccume serviced... recommend getting a less cheap vaccume intended for heavier duty next time around.

In order to prevent the aforementioned problem I cut out all of the Hoover filters, dramatically reducing the motor's workload and extending the number of consecutive minutes for which I was able to vacuum without triggering the thermal protector. The thermal protector itself is the next component that I intend to disable.

Sounds like you have a clog, which is a fairly common problem with these.
Check the air inlet immediately aft of the brushroll for clogs, then make sure the main wand and hose are also clear. If you have the machine on, check at the end of the hose for suction. This is a fairly common problem for all uprights with tools on board. Their airflow is very low, so they tend to clog up easily and then overheat the motor.

Tried different outlets, tried waiting for it to cool a bit, tried emptying case. now i just washed filter, but will have to wait till it dries for results.
