Why did my vacuum quit running while in use?

My Kenmore Upright Vacuum model no. 116.36623501 while vacuuming it just cut off. Now it will not power on. Why?

Your vacuum cleaner has 3 electronic control boards in which any one of the 3 may have failed. The Thermal Protector may have tripped in the motor and it did not reset after the motor cooled down. It could be a loose wire connection, failed on/off switch, or one of the 2 other electronic boards may have failed. It could have a broken wire in the power cord too. It will require a volt/ohm meter to test and diagnose the failure.

I recommend taking the vacuum in for diagnosing and repair.
