Possible Causes

Evaporator thermistor reading too warm, Control board not initiating harvest, Ice size set to maximum with sensor fault, Poor water circulation

Safety first: Unplug the unit and allow the ice block to melt completely before restarting.

Reset ice size: Set the ice size to small or medium.
Check water pump: Ensure the pump is circulating water evenly over the evaporator; replace if weak.
Inspect thermistor: Verify the evaporator sensor is firmly attached and not insulated from the metal surface.
Replace sensor or board: If overfreezing recurs, replace the evaporator thermistor. If the issue persists, the control board may be faulty.
