Repair or replace

A 600 Series with a failed compressor

The costliest repair this site publishes, on the generation most likely to reach it. When the arithmetic still holds, and the conditions under which it stops.

The repair against the replacement

Figures from this site's published bands and its replacement comparison — the number for your machine is agreed at the visit, before anything is opened.
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.

The word compressor does more damage on this generation than the failure usually does. It gets said on the telephone, a replacement machine is priced the same evening, and nobody has yet established whether the part that stopped working is the sealed pump or the electrical hardware bolted to the outside of its housing.

Seven machines wearing twenty model numbers

This family runs to seven base configurations — 601R, 601F, 611, 632, 642, 650 and 690 — sold under twenty model numbers, because most of them were offered in three exterior treatments. The letter after the slash records the door and nothing more: framed, overlay for a custom panel, or stainless. Functional parts are common straight across all three, which is why a quote should not move because of the finish on the front of your kitchen.

The fork that sets the size of the job

The electrical components mounted on the outside of the compressor housing are, in Sub-Zero’s own parts definitions, not sealed-system parts at all. One route is an accessible part change with the refrigerant circuit never disturbed. The other is the highest band this site publishes. Nothing audible at the door separates them, which is why a diagnosis that arrived without instruments is a guess wearing a technician’s clothes.

What actually decides it here

Not the age of the cabinet, and not the size of the quote on its own. What the replacement row buys is a shell you already own, standing in an opening somebody was already paid to make for it. What turns the answer over is history: a circuit that has never been opened is worth the largest repair on this site, and one that has been opened, repaired and has failed again is saying something the first failure did not.

What we usually find

  1. A compressor that hums, pulls current for a second or two and then drops out again

    The electrical hardware bolted to the outside of the housing far more often than the pump sealed inside it. Sub-Zero's own parts definitions keep those components out of the sealed system, and the work follows the same line.

  2. A cabinet that cools for an hour, gives up, then comes back and does it again

    A restriction ahead of a tired pump as often as the pump itself. Gauges separate the two where the machine stands, and which one it is changes what the repair involves rather than only what it is worth.

  3. A model number read off with its slash and letter and searched for as though it were a separate machine

    The same cabinet in a different coat. Three exterior treatments were offered across seven configurations here, and everything behind the door is shared between them, so the part being hunted usually exists under a shorter number.

    Quoted after the diagnosis

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 fault has been narrowed past the start hardware to the sealed circuit itself
  • The base model is one of the seven in this family, so the functional parts pool behind it is wide
  • This would be the first time the refrigerant circuit on this cabinet has been opened

Replace it if

  • The circuit has already been opened once, repaired, and has now failed a second time
  • The case has been standing wet and the insulation behind the liner is no longer dry
  • The cabinet is being moved and the run it stands in is being rebuilt around something else

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

Does the letter after the model number change the repair?
No. It records the door treatment only — framed, overlay for a custom panel, or stainless steel — and the refrigeration, the controls and the fans behind it are shared across all three. Quote the base number when you call Sub-Zero Repair Pro Los Angeles on (310) 844-1973, and the letter afterwards if you know it.
How do you tell a failed compressor from a failed start component?
Not from the kitchen. Both leave you with a machine that tries, makes a noise and stops. The difference is found with a meter at the housing and, where that comes back clean, with gauges on the circuit, and it is the difference between an accessible part change and opening the refrigerant system.
