Swan Partial Evaporator Blockage or Gas Distribution Issue

The ice maker produces ice only on one side of the evaporator or unevenly across the plate.

Safety Warning

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Partial blockage in the capillary tube, uneven refrigerant distribution, localized scale buildup on the evaporator, or a weak compressor.

How to Fix / Troubleshooting

Safety first: Unplug the unit before touching the evaporator. Do not attempt to open the sealed system.

Descale evaporator: Clean the entire evaporator surface with a vinegar solution to remove mineral deposits that can affect heat transfer.
Check airflow: Ensure the condenser fan and vents are clean to maintain proper system pressures.
Monitor pattern: After cleaning, run a cycle and observe the freezing pattern. If only part of the evaporator frosts, a sealed system issue is likely.

Sealed system problems (capillary blockage, gas distribution) require specialized tools and are not user-serviceable. Consult a refrigeration technician for further diagnosis.
