The present invention relates to a method, a device and a computer program for deciding when to terminate a defrosting cycle within a refrigerated transport container (1) where the container (1) includes: - a transport volume (45), - a cooling unit comprising at least an evaporator (16) arranged in a cooling space (41), - a return air grid (42) arranged to separate said cooling space (41) from said transport volume (45), - means for sensing temperature indicative of the return air temperature of air returning to said cooling space (41) from said transport volume (45) or the temperature of the return air grid (45), - means for actively heating said evaporator (16) during defrosting cycles, and - a processor configured for controlling at least the duration of said defrosting cycles, The method includes the steps of: - establishing one or more indicators indicative of frost and/or ice build-up on said return air grid (42), and - deciding to terminate a defrosting cycle only when said one or more indicators indicative of frost and/or ice build-up on said return air grid (42) indicate that said return air grid (42) is free of frost and/or ice.
