Three Sub-Zero decisions: the compressor, the evaporator and condenser assembly, and the control board. This hub is unlike the other brand hubs in the section, because two of its three pages are sealed-system work and because the machine beneath them is built in. A Sub-Zero is installed into cabinetry and expected to run for decades, which pushes the repair-or-replace line considerably further toward repair than it sits anywhere else here.
So each page weighs something the mass-market pages never have to: replacement is not a delivery, it is a cabinetry project. The compressor and evaporator pages establish the fault first — a unit that cannot hold temperature with a clean condenser and working fans, against one starved by a restriction — and only then compare a specialist repair with what replacing a built-in actually entails. The control board page is the bounded one of the three.
Two of these three repairs open the refrigerant circuit and are restricted work regardless of skill; the control board is not. On a built-in there is a second constraint that is purely physical, because the unit has to come out of its opening before most of the work can begin, and that belongs in the cost rather than as an afterthought.

Sub-Zero Compressor Replacement
On a Sub-Zero, a compressor repair is almost always worth it — the brand is built for 20-plus years. Here is the age-and-cost verdict and warranty facts.
Sub-Zero Evaporator & Condenser: Worth Fixing?
A Sub-Zero evaporator and condenser repair restores cooling for far less than replacing the unit, so it is almost always worth it. The 50% rule by age, why coil cleaning matters, and the constant-running fix.
Sub-Zero Fridge Control Board: Worth Fixing?
A Sub-Zero refrigerator control board is almost always worth replacing — it costs a fraction of the unit, and refurbished boards keep even discontinued models running. Where the boards live and when to replace.
