1. A method of operating a blender having a jar including blending blades therein, a base, a motor mounted within the base, a controller and a temperature sensor, the method comprising the steps of:

  • a) positioning foodstuff in the jar;

    b) mounting the jar to the base such that the blending blades are in mechanical communication with the motor;

    c) operating the motor to rotate the blending blades within the foodstuff and blend the foodstuff;

    d) sensing a temperature of the motor with the temperature sensor;

    e) communicating the temperature of the motor to the controller;

    f) comparing the sensed temperature of the motor to a predetermined high temperature range using the controller, the controller sending a signal to the motor to cancel operation of the motor when the sensed temperature of the motor is within the predetermined high temperature range; and

    g) operating the motor at a rotating speed in a reduced mechanical load cycle to cool the motor.
