E6 error appears; ice maker may run water but does not freeze properly; cycles may abort.

Safety first: Disconnect power before touching internal components.

Check for heavy ice buildup:

• Remove the ice basket and inspect the evaporator grid. If it is encased in thick ice, power off the unit and allow it to fully defrost (this can take several hours). Do not chip ice with sharp tools.

Inspect sensors:

• Locate the evaporator temperature sensor and any ice thickness sensor (often a small metal probe or plastic paddle that contacts the ice).
• Ensure sensors are firmly attached and not dangling away from the evaporator surface.
• Check wiring for damage and confirm connectors are secure on the control board.

Clean and reset:

• Wipe sensors gently with a soft cloth to remove mineral deposits.
• Reassemble, plug in, and run a full cycle. Observe whether ice forms and releases normally.

If E6 returns: Replace the evaporator temperature sensor or ice thickness sensor as indicated by your model's service documentation. If new sensors do not resolve the issue, the main control PCB may need replacement.
