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.HA_DH_Vacuums
