Sub-Zero Ice Maker Repair

Sub-Zero undercounter ice makers — the UC-15I clear ice model and UC-15IP standard model — produce high-clarity ice through a controlled freeze-and-harvest cycle. When ice production stops, ice comes out cloudy or small, or the cleaning-due alert cannot be cleared, professional repair restores consistent, reliable ice output.

Common Sub-Zero Ice Maker Problems We Fix

• No ice production — water inlet valve or harvest cycle fault (no-ice alert, EC30)
• Slow ice production — evaporator plate inefficiency or water flow restriction (slow-ice alert)
• Water leaking — water inlet valve or drain line fault (water-leak alert)
• Harvest stuck — harvest heater or sensor fault preventing ice release (harv-stuck alert)
• Cleaning-due alert not clearing — mineral scale in water circuit preventing cycle completion (cleaning-due alert)
• EC30 fault — harvest system fault requiring component-level diagnosis (EC30)

Error Codes We Diagnose

We diagnose all Sub-Zero ice maker fault codes, including EC30, the no-ice alert, slow-ice alert, water-leak alert, harv-stuck alert, and cleaning-due alert. We run a full harvest cycle test during the diagnostic to confirm the root cause before any part is sourced.

Models We Service

• Sub-Zero UC-15I undercounter clear ice maker (15")
• Sub-Zero UC-15IP undercounter ice maker standard (15")
• Sub-Zero undercounter ice makers (all configurations and production years)
