# Sub-Zero built-in refrigerators

### What a built-in refrigerator asks for that a freestanding one does not

A column or an over-and-under cabinet is fitted into the kitchen rather than placed in it: panelled to match the cabinetry, levelled carefully, and often plumbed. That decides how the unit comes out and how long the appointment runs, and it is why we ask about the installation before the visit rather than on arrival.

### The symptoms we are called out for most

- One side warm on a dual-refrigeration cabinet while the other holds perfectly — two sealed systems, one of them in trouble
- The whole cabinet drifting a few degrees, usually a condenser nobody has cleaned since the kitchen was built
- Frost building on one shelf, which points at the defrost circuit or the evaporator rather than at the compressor
- A service light or wrench symbol with no obvious change in temperature

### Legacy series are worth keeping

The 500, 600 and 700 Series units still working in South Florida kitchens were built to be repaired, and most of the time repairing them is the right call. Parts for them are scarcer than for current models, so we confirm the part is the problem before ordering it — and when the work approaches what the unit is worth, we say so on the visit.
