DIAGNOSIS The ice thickness sensor is cutting the freezing cycle short. This is usually due to incorrect sensor position or a low water flow rate.
FIX Check the external water bottle. It must be positioned higher than the ice maker to maintain proper water pressure. Ensure the bottle is full. Clean the water intake valve and filter screen to ensure unrestricted flow.
IF THAT DIDN'T WORK The ice thickness probe may need adjustment. It is a small metal rod near the evaporator. Gently bend it slightly closer to the evaporator plate—no more than 2mm. This allows the ice to grow thicker before triggering the harvest cycle.
HEADS UP Ambient temperature above 90°F can also cause small ice. The unit works best between -60°F and 90°F. High room temps reduce efficiency and can shorten freeze cycles.
