17. A method for controlling a power tool device, the method comprising:
determining a temperature difference between a first temperature value associated with a first temperature sensor and a second temperature value associated with a second temperature sensor, wherein the first temperature sensor is configured to sense an ambient temperature, and wherein the second temperature sensor is configured to sense a temperature of an electrical component;
calculating an amount of heat generated by the electrical component;
comparing the temperature difference and the amount of heat generated by the electrical component to a look-up table; and
providing, in response to the comparison indicating an abnormal temperature condition of the electrical component, a notification using an indication device.
