Provided are an apparatus and a method for monitoring a hot surface of a cook top. The apparatus includes a display unit (30), a temperature detecting sensor (2), and a microprocessor (5). The display unit (30) displays a state of a hot surface and an operation error of a hot plate as a heater operates. The temperature detecting sensor (2) is installed closely to the heater (110,120) to detect heater temperature greater than set temperature. The microprocessor (5) compares the heater temperature greater than the set temperature that is detected by the temperature detecting sensor (2) with heater temperature greater than the set temperature that is expected by an elapse of an operating time of the heater to judge one of a hot surface and an operation error of the hot plate, and controls the judgment results to be displayed using the display unit. |
