Sub-Zero Refrigerator Repair
Sub-Zero Warranty Explained: Two Years Full, Then Five and Twelve on the Sealed System
Sub-Zero's residential warranty has three layers: two years of full parts-and-labor cover, five years full on the sealed system, and a limited sealed-system warranty to year twelve that pays for the part but not the labor. All of it counts from the installation date.
If your Sub-Zero is less than two years past its installation date, its warranty pays for parts and labor on any part that is defective in materials or workmanship. If it is less than five years in, the sealed system — compressor, condenser, evaporator, drier and the tubing that joins them — is still covered in full, parts and labor. From year six to year twelve Sub-Zero still repairs or replaces a defective sealed-system part, but every other cost of the job, labor included, is yours.
That is the whole shape of it. Everything below comes from Sub-Zero’s own published documents, listed at the end of this page, and where those documents are silent we have not filled the gap with a guess. The useful detail is in four places: when the clock started, what is excluded, what Sub-Zero will ask you for, and whose number to ring in which year.
Year by year, in one table
| Period, counted from installation | What is covered | Who pays the labor |
|---|---|---|
| First 60 days | Cosmetic defects on stainless doors, panels, handles, frames and interior surfaces | Sub-Zero |
| Years 1–2 | Any part defective in materials or workmanship (full warranty) | Sub-Zero |
| Years 1–5 | Compressor, condenser, evaporator, drier and connecting tubing (full sealed system warranty) | Sub-Zero |
| Years 6–12 | The same five sealed-system components, part only (limited warranty) | The owner |
| Any time | Replacement water filters and air purification cartridges | Not covered |
Two rows catch owners out. The first is the heading of the left-hand column: Sub-Zero measures from the date of original installation, not from the receipt. On a renovation where the refrigerator sat in a garage waiting for the cabinetmaker, that works in your favour — and it is the reason the installation date belongs in the same folder as the invoice. The second is the bottom row. Filters and air cartridges are consumables, and ice that has turned small and hollow because a filter stayed in for two years is not a warranty matter at all.
Years six to twelve: the part is covered, the job is not
This is the layer most people misread, because “twelve-year warranty” sounds like twelve years of free repairs. It is not that. In the limited period Sub-Zero supplies the repaired or replacement component, and the diagnosis, the labor and the rest of the job are the owner’s to pay for.
Sealed-system work is not a small job either. Sub-Zero’s current use and care guides warn that the appliance contains flammable refrigerant and that only technicians trained for it may work on the equipment. On our own price list a compressor or sealed-system repair sits in the $940–$2,150 band, and that band describes the whole repair; before you book anyone in years six to twelve, ask Sub-Zero’s customer care how the covered part is supplied, because the warranty pays for the part and not for the visit. Set against $8,660–$19,630 for a comparable new built-in, appliance only, a covered compressor in an otherwise sound cabinet is usually still worth fitting.
What Sub-Zero excludes
The warranty applies only to products installed for normal residential use in the fifty U.S. states, the District of Columbia or the ten Canadian provinces. Within that, it excludes defects caused by negligence, accident, or improper installation, maintenance or repair.
In a fitted kitchen the installation clause is the one to take seriously. For its Designer units (ID, IC, IT), Sub-Zero warns that the kickplate must not be completely covered by a custom toe kick or enclosed in cabinetry, and that this can lead to sealed system failure even after the unit has run that way for years. An owner does not think of a cabinetmaker’s toe kick as “installation”, but a sealed-system claim on a smothered kickplate can be read exactly that way. If your kitchen was finished with a continuous toe kick, raise it with the installer while the warranty is young.
Maintenance is the other clause. Sub-Zero asks owners to clear the condenser at intervals of six to twelve months, sooner in a house with pets, and says chemical condenser cleaners are neither necessary nor recommended. A vacuum with a soft brush, worked in the direction of the fins, is the entire job; our spring cleaning notes walk through it.
Registration, and the four things a claim asks for
Sub-Zero’s online Product Registration registers the appliance and activates the warranty. When you ask for warranty service, Sub-Zero wants four things: the model and serial numbers off the rating plate, the date the unit was installed, and which dealer sold it.
The rating plate — Sub-Zero calls it the serial tag — is not on the back of the cabinet. On a Classic (BI, CL) over-and-under, open the refrigerator door and look up by the top hinge; on a Classic side-by-side it is on the inside of the freezer door; Designer Column units (IC, DEC) have it inside the middle drawer near the drawer guide; Designer Tall units (IT, DET) have it inside the cabinet to the left of the upper drawer. The tag also prints a manufacture date, which is useful but is not the date the warranty runs from.
The letters at the front of the model number tell you which line you own. A model starting CL is a current Classic, and one starting BI or BW is a Legacy Classic (the line was once sold as Built-In). DET and DEC mark the current Designer; IT, IC, ID and IW mark the Legacy Designer, once called Integrated; UC means Undercounter.
Display units and outdoor models have their own terms
Two variations change the arithmetic. A Sub-Zero display product sold three to seven years after the manufacturer’s invoice date gets a full one-year warranty and a limited five-year sealed system warranty, and Sub-Zero needs a copy of the paid invoice to activate it. A product approved for outdoor use, by model and serial number, gets one year of full cover, parts and labor, and five years of full sealed-system cover.
If yours came off a showroom floor, find out which document applies before assuming the standard two, five and twelve.
Whose number to ring, year by year
- Inside the full cover — years one and two for any part, years one to five for the sealed system: Sub-Zero’s own customer care. That is what the warranty exists for, and an outside repair inside that window gives the claims department a reason to decline.
- Years three to five, for a part outside the sealed system — a fan motor, a control board, a door gasket, an ice maker: the full warranty has ended for that part, so you choose who does the work and you pay for it.
- Years six to twelve, sealed system: ask Sub-Zero how the covered part is supplied before booking any labor. The labor is yours whoever does it.
- After year twelve: no warranty, and the decision is a straight comparison between the quote and a new built-in with its panels and fitting.
Sub-Zero Repair Westwood is independent. We are not affiliated with Sub-Zero and are not part of its service network, so if you ring us about a unit still inside its full cover we will say so and send you back to the manufacturer before anything is booked.
Wolf and Cove appliances in the same kitchen carry warranty documents of their own; this page covers Sub-Zero refrigeration only, because that is all this shop repairs.
Extended plans are a separate contract
A protection plan bought from a retailer is not part of Sub-Zero’s warranty. It is a contract with whoever administers the plan, and three of its clauses matter more than the rest. Does work need approval before it starts? Paying first and claiming afterwards is the commonest way a valid claim is lost. Can the plan settle by replacing the appliance instead of repairing it? On a panelled built-in that leaves the panels, the opening and the fitting to you. And may you choose your own repairer, or must you take whoever is on the plan’s list?
A Westwood note: the water, the filter and the folder
Westwood’s tap water comes from the Dedham-Westwood Water District: groundwater from wells by the Neponset River near University Avenue and by Rock Meadow Brook near Dover Road, treated to remove iron and manganese, chlorinated, and supplemented with MWRA water. The District’s 2025 report put hardness at 74.1 to 134 ppm, 4.3 to 7.8 grains per gallon.
None of that is a warranty question in itself. But the water filter that deals with it is a consumable the warranty excludes, and on current Classic and Designer units Sub-Zero rates it for twelve months or 750 gallons. Change it on schedule, keep the receipt, and keep it in one folder with the invoice, the installation date and a photograph of the rating plate. That folder answers every question a claim will ask.
Out of cover, or not sure
A visit from us is a flat $95 for the call-out and the full diagnosis; go ahead with the repair and the $95 comes off it, and the figure for the repair comes before anything is opened.

Still asked afterwards
- Does the Sub-Zero warranty start on the day I bought the refrigerator?
- No. Sub-Zero's Residential Limited Warranty counts both the two years of full cover and the five years of sealed-system cover from the date of original installation, so a unit that waited crated through a renovation has not lost those months. Display units sold three to seven years after the manufacturer's invoice date are the exception: they carry shorter terms of their own and need a copy of the paid invoice.
- My Sub-Zero compressor failed in year eight. What does the warranty pay for?
- The part. Under the limited twelve-year sealed system warranty, Sub-Zero repairs or replaces a defective compressor, condenser, evaporator, drier or connecting tubing, and the owner pays all other costs, labor included. Inside the first five years the same failure is covered in full, parts and labor.
- Does an independent repair void the Sub-Zero warranty?
- The warranty excludes defects caused by improper installation, maintenance or repair, so while any full cover is still running the sensible first call is Sub-Zero's own customer care. We are independent and not affiliated with Sub-Zero; if you ring us about a unit that is still inside its full cover, we will tell you so before anything is booked.
