If your ice machine is producing ice that is either too small or too large, it could be due to several issues, including a malfunctioning ice thickness probe, clogged water valve, or inadequate cooling. These components play key roles in regulating the ice-making process, and if they fail, the ice size can be compromised. Regular maintenance every six months is vital to ensure all parts are functioning correctly, preventing issues that affect ice quality and machine performance.

Main Issues When Ice Machine Producing Ice That Is Too Small or Too Large
Description and Troubleshooting of Problems
Water Valve Is Malfunctioning
In some ice machine models, ice drops when the water reservoir is empty. The machine assumes that once the water has frozen, the ice is ready to be released. However, if the water valve is clogged and restricts water flow, the reservoir may only fill partially within the allotted time. This results in smaller ice cubes since there wasn’t enough water for full-sized cubes. This issue often occurs due to mineral buildup from hard water, which reduces water pressure and flow.
Ice Thickness Probe Is Malfunctioning
The ice thickness probe is a sensor that monitors ice formation and triggers the ice-dumping process once the ice reaches the correct size. However, constant contact with water can cause buildup, which may interfere with its accuracy, resulting in ice that’s too small or too large. If the probe malfunctions entirely, it may not respond, leading to excessive ice buildup and the ice machine entering a safety mode, shutting down. The machine may restart after some time or require manual intervention but will stop again if the sensor remains faulty.
Compressor Is Not Cooling Sufficiently
The compressor not cooling adequately can lead to undersized ice, often tied to issues in the cooling system. This may occur if the evaporator coil is cold but insufficient for proper ice formation. Causes include:
- System restriction: A blockage preventing proper refrigerant flow
- Freon leak: A slow leak that worsens over months, eventually impairing performance
- Faulty fan or sensor: If the fan fails, the condenser coil overheats, reducing cooling efficiency
A professional inspection is essential to diagnose and resolve the issue effectively.
Circulation Pump Is Malfunctioning
The circulation pump is responsible for moving water over the coil where the ice forms. It draws water from the reservoir and remains submerged, which requires regular cleaning, as dirt often collects and obstructs its proper function. Common issues include clogs in the pump, tubes, or spray, reducing water flow and affecting ice formation. Initially, this causes slight pressure drops, but over time, it leads to severe clogging, eventually halting the pump’s operation completely.
Repair Cost
| Water valve cleaning or replacing | $280 – $380 |
| Ice thickness probe repairing | $280 – $385 |
| Compressor repairing | $350-$480 |
| Circulation pump cleaning or replacing | $280-$485 |
The cost of fixing an ice machine varies based on factors like the brand, model, and the complexity of the problem.

I’ve encountered a problem very similar to what you describe in this article. My ice machine is producing ice that is very small in size. Is there anything I can do to resolve this issue on my own?
Of course, you could take a few steps that might help identify the cause of the problem, such as checking the water filter, inspecting the water pressure, or adjusting the ice size settings. However, in practice, these are unlikely to solve the issue. A specialist and the proper tools are likely needed for this.
