A system and method for controlling an icemaker assembly to prevent premature ice harvests is provided. In particular implementations, normal icemaker operations, including ice cube harvesting, can be suspended when an ice cube level in an ice cube storage bin is detected to exceed a predetermined threshold or when a command is received to prevent harvesting. When a command to prevent harvesting is received, communication from an ice cube storage bin sensor can be disconnected, for instance, after a current harvesting cycle is complete. The communication from the ice cube storage bin sensor can be reconnected following a time interval or after receiving a command to re-start the normal operations.
