The repair against the replacement
| What it takes | Range |
|---|---|
| Compressor or sealed-system repair | $1,510–$3,440 |
| Buying another one instead | $12,710–$21,440 |
That last row buys a like-for-like built-in on its own, with nothing allowed for fitting it or for the joinery around it. Every figure above it is being weighed against that, which is why a structurally sound cabinet is usually worth putting right even when the quote makes you wince.
What makes this look worse than it is: the freezer stops, the noise behind the grille changes, and the assumption forms that the machine has died. The refrigerator beside it is sitting exactly where it was set. That combination is not a cabinet in decline. It is one circuit out of two, and the other is telling you so.
Two systems, one cabinet
Sub-Zero built these combination models with separate refrigeration for each compartment — the current guides still call it Dual Refrigeration — so the freezer stays dry and cold while the fresh-food side keeps its humidity and neither passes odours to the other. The service tables follow suit: every combination model gets one set of running pressures for the refrigerator and another for the freezer, and only the single-compartment columns get one.
For a decision, that is the point. A failure has a side. Half this machine has never been opened and does not need to be priced.
What gets measured before anybody says compressor
The failed compartment is worked through in the manufacturer’s order. Any codes the control is holding come first, then the airflow, the condenser and the fans, then the defrost hardware on that side, and only after all of it the circuit itself. A compartment that will not cool has several cheaper explanations than its compressor, and three of them sit in lower bands than the one above.
Where pressures are eventually taken, they are read as a pair. Two low readings mean a leak; low against high means something is restricted; high against low is a compressor no longer pulling its weight. Only that last reading makes this page’s headline true.
The condition that decides it
Whether the other half is intact. One sound circuit, a square cabinet and doors that still seal make a strong case for repairing the side that went, because what the replacement row buys is already in your kitchen and working. When both circuits have been opened, or a single-system column has lost its only compressor, the last row deserves a serious look.
What we usually find
-
A freezer that has given up while the refrigerator alongside it is still at temperature
One circuit of two. The manufacturer lists its normal running pressures separately for each compartment on these models, which is the plainest sign that they are two machines in one shell.
Compressor or sealed-system repair $1,510–$3,440
-
A dead compartment attributed to its compressor before any pressures were taken
Very often the evaporator fan or the defrost circuit on that side alone. Either one leaves a compartment unable to hold while its neighbour carries on behaving perfectly.
Evaporator or condenser fan motor $330–$750
-
Both compartments drifting warm together through a hot spell in the Valley
Not this scenario at all. When the two sides move as one, the shared hardware is the suspect — the condenser they both reject heat through, and the air reaching it.
Evaporator or condenser fan motor $330–$750
-
A single-compartment column quoted as though it had a spare system in reserve
One circuit by design. The all-refrigerator and all-freezer cabinets were built with a single sealed system, so there is no other half to fall back on and the decision covers the whole machine.

Which of these it is gets settled at the visit, before a part is ordered — Sub-Zero Repair Pro Los Angeles, (310) 844-1973.
Which way it points
Repair it if
- The untouched side is still holding its temperature after the failure
- Pressures have been read on the failed circuit and the fault has a name
- The box is square, the doors seal and the opening was made for this cabinet
Replace it if
- Both circuits have now been opened at least once each
- The failed side is the refrigerator on a cabinet whose freezer already went
- A single-system column has lost its only compressor and is tired elsewhere too
If your machine sits between the two columns, that is what the diagnosis is for: Sub-Zero Repair Pro Los Angeles measures it first and gives you the figure before any of it is committed to — (310) 844-1973.
Follow-ups
- Can I keep using the half that still works?
- Usually yes, for a while. The working compartment has its own circuit and is unaffected by the failure next to it, so the food moves across and the machine keeps earning its space. Book the diagnosis rather than living with it though: Sub-Zero Repair Pro Los Angeles, (310) 844-1973.
- How do I know my cabinet has two systems at all?
- By the model, not by the doors. The combination built-ins with a refrigerator and a freezer in one case carry two circuits; the tall single-purpose columns carry one. The plate inside the door settles it in seconds, and the series reference on this site walks through which family yours belongs to.
