The 685 is a built-in side-by-side refrigerator/freezer from the 600 Series with a through-the-door ice and water dispenser, published in framed, partial-framed, and overlay door styles. It’s no longer produced. A cabinet that recovers slowly after the door’s been held open, or one that holds temperature overnight but drifts warmer through the day, are the […]

The 700TC is a 700 Series Sub-Zero refrigerator, another of the brand’s early built-in generations. Like the other legacy families still in service, it reports very little through its own display, so a problem shows up as a change in how the cabinet actually performs rather than as a code. The pattern we see most […]

The 632 is a 600 Series side-by-side refrigerator/freezer with an automatic ice maker built into the freezer side — it’s sometimes mistaken for a standalone ice machine because of that, but it’s a full refrigerator/freezer. The model and serial plate sits at the top of the side frame inside the unit, near the hinge, which […]

The 642 shares the same 600 Series cabinet as the 632, with its ice maker built into the freezer side rather than sold as a separate machine. The model and serial plate is in the same spot as its sibling — the top of the side frame, inside the unit, near the hinge. Where the […]

The 695 is the 600 Series side-by-side with an ice and water dispenser built into the door — the feature that sets it apart from the 632 and 642. That dispenser has its own fill valve and water line, separate from the refrigeration system itself. When a 695 stops delivering water, or only delivers it […]

The 532 is a 500 Series refrigerator — the oldest Sub-Zero cabinet family still turning up in working kitchens. It was built before the brand added the diagnostic displays found on later models, so instead of a code, this generation typically just shows a problem through how the cabinet is actually performing. On a 532, […]

The 550 belongs to the same 500 Series family as the 532, Sub-Zero’s oldest cabinet generation still commonly serviced. Like its siblings, it predates on-board diagnostic displays, so an owner notices a problem through the cabinet’s behavior rather than a code. The pattern we see most on a 550 is one side running warm while […]

The 650 is a 600 Series refrigerator with a built-in ice maker, which many owners end up contacting us about as a separate issue from the main cooling system. Like other 600 Series units, it’s an older generation with limited on-board diagnostics. Cooling complaints on a 650 usually follow the same pattern as its siblings […]
