Abstract To prevent frost and/or ice build-up and/or accumulation on a return air grid in a cooling space.SOLUTION: In a method for deciding when to terminate a defrosting cycle in a refrigerated transport container (1), the container includes: a transport volume (45); a cooling unit disposed in a cooling space (41); a return air grid (42) arranged to separate the cooling space from the transport volume; means for sensing a temperature indicative of the return air temperature of air returning to the cooling space from the transport volume or a temperature of the return air grid; means for heating an evaporator during the defrosting cycle; and a processor configured to control at least a duration of the defrosting cycle. One or more indicators indicating frost and/or ice build-up on the return air grid, are established, and the defrosting cycle is terminated only when the one or more indicators indicating frost and/or ice build-up on the return air grid indicate that the return air grid is free of frost and/or ice.
