Sub-Zero Refrigerator

Sub-Zero 511

Model # 511

Sub-Zero refrigerator repair

The 511 pairs a built-in refrigerator with a roll-out freezer drawer rather than a full side-by-side freezer section, and both compartments are controlled from the same panel on the back wall near the top of the refrigerator. It’s a 500 Series model, no longer produced, with features like an adjustable dairy compartment and roll-out refrigerator basket typical of that generation.

Two issues are specific to the drawer design on a 511: frost building up inside the freezer compartment, and the drawer itself no longer running square on its slides, so it doesn’t seal when pushed home. The cabinet also shows the same overnight-hold, daytime-drift pattern common across 500 Series refrigerators.

FAQ

Sub-Zero 511 FAQ

Both the refrigerator and freezer controls are on the back wall of the refrigerator, near the top — not on the freezer drawer itself.

Usually the drawer has come out of square on its slides after years of use, so it no longer closes flush against the gasket.
