Icemaker appliance and method for acoustic harvest detection

A refrigerator appliance, the refrigerator appliance comprising a freezer compartment in which an ice maker appliance is provided, the ice maker appliance defining a vertical direction, a lateral direction, and a transverse direction, the ice maker appliance comprising:

• a frame and a mold tray selectively supported by the frame, the mold tray comprising one or more ice forming shapes defined therein;
• a motor coupled to the frame and operably coupled with the mold tray to selectively rotate the mold tray with respect to the frame in each of a first direction and a second direction;
• an acoustic sensor;
• and
• a controller operably coupled with the motor and the acoustic sensor, the controller configured to perform an operation, the operation comprising:
• initiating a first harvest routine;
• obtaining an acoustic signal during the first harvest routine;
• determining similarity or dissimilarity between the acoustic signal and a baseline signal;
• and
• initiating a second harvest routine if dissimilarity between the acoustic signal and the baseline signal is determined.
