The disclosure is related to a method for verifying an immersion cooling system. The immersion cooling system includes a first sensor, a second sensor and at least one third sensor. The method includes: obtaining a first difference value; determining whether the first difference value is smaller than a first threshold value; determining that the first sensor and the second sensor are in normal operation when the first difference value is smaller than the first threshold value; when the first difference value is not smaller than the first threshold value, determining an operating condition of the first sensor or the second sensor according to a relationship between a sensor value of the at least one third sensor and the sensor value of the first sensor, or a relationship between the sensor value of the at least one third sensor and the sensor value of the second sensor.
