The invention discloses an electromagnetic heating system, and a method and a device for detecting the thermistor of the electromagnetic heating system. The method comprises the following steps of: recording the temperature value obtained by the thermistor as a first temperature value when the electromagnetic heating system is powered on; recording the temperature value obtained by the thermistoras a second temperature value when the electromagnetic heating system is in a standby state; obtaining the maximum temperature value and the minimum temperature value of the temperature value obtainedby the thermistor in a continuously preset second preset time every other first preset time during the heating process of the electromagnetic heating system; and judging whether the thermistor is ina failure state or not according to the first temperature value and / or the second temperature value, the maximum temperature value, and the minimum temperature value. The method for detecting the thermistor of the electromagnetic heating system judges whether the thermistor fails or not according to the static temperature values at the time of power-on and standby and the dynamic temperature valuein the heating process, so that the accuracy and the reliability of the judgment are greatly improved, and the safety of the system is improved.
