A method and apparatus for defrosting an evaporator of a refrigeration system including a defrost heater and a controller operatively connected to the evaporator and a defrost heater is provided. The method comprises initiating a defrost cycle to energize the defrost heater to defrost the evaporator, monitoring a temperature of the evaporator, terminating the defrost cycle by de-energizing the defrost heater when a low temperature termination point of the evaporator is reached when in a low temperature defrost cycle, and terminating the defrost cycle by de-energizing the defrost heater when a high temperature termination point of the evaporator is reached when in a high temperature defrost cycle.
