Commercial Sub-Zero Ice Maker Control Board Failure — South Queens ZIP 11421, NYC

Small or hollow ice cubes usually indicate low water pressure or a partially clogged water inlet valve. Mineral deposits can clog the small screens in water inlet valves over time. We clean or replace the valve and flush the water line.

The most common causes are a failed water inlet valve, a broken ice maker module, a clogged water filter, or a freezer temperature that's too warm (above 10°F). We carry parts for Samsung, LG, Whirlpool, GE, and most major brands.

Off-tasting ice is usually caused by a dirty or old water filter, a contaminated water line, or mold in the ice maker bin. Replace your water filter every 6 months, sanitize the ice bin, and flush the water line. If the issue persists, the filter head or water line may need replacement.
