Abstract: A system and method for defrosting a load are presented. Radio frequency (RF) signals are supplied to a transmission path that is electrically coupled to one or more electrodes that are positioned proximate to a cavity to cause the one or more electrodes to radiate RF electromagnetic energy. An RF power value of the RF signal along the transmission path is periodically measured resulting in RF power values and a rate of change of the RF power values is determined. A low-loss indicator value is determined using the RF power values, wherein the low-loss indicator value is at least partially determined by a dielectric loss of a load in the cavity. A controller determines, using the rate of change of the RF power values and the low-loss indicator value, that the load is in a defrosted state and stops supplying the RF signals.
