Abstract
A method of defrosting a eutectic plate of a refrigeration system involves activating a defrost system when a power source is connected to the refrigeration system. The defrost system is operated for all or a portion of a defrost cycle and is then deactivated. The initiation of a subsequent defrost cycle is prevented until the power source has been disconnected from the refrigeration system for at least a selected amount of time. A defrost system may include a controller programmed to carry out the method and automatically initiate a series of defrost cycles.
