The 501F is a built-in all-freezer from Sub-Zero’s discontinued 500 Series, with roll-out freezer baskets, adjustable door shelves, and a pull-out ice container with an automatic ice maker.
A unit running constantly without ever cycling off is the issue reported most on a 501F, often connected to ice forming over the drain and leaving water beneath the lowest basket. Cloudy cubes, slow ice, or no ice at all from the ice maker is the other common call, usually unrelated to the main cooling issue — keep food storage near 0°F, the standard freezer target, and verify it with a thermometer rather than the display alone.
