Genuine Sub-Zero & Wolf OEM Parts
We are a repair service, not a parts retailer — we do not sell or ship parts over the counter. What we do is source the exact genuine OEM Sub-Zero or Wolf part matched to your model and serial number and install it during the repair, with the part number printed on your invoice. The $89 diagnostic is credited toward the repair, and the work carries our 365-day labor warranty. Call (650) 484-4687.
Why exact model + serial matching matters
A single Sub-Zero or Wolf model number can span several hardware revisions across its production years. The same BI-42 may have shipped with two or three different evaporator-fan motors; the same control board part can carry different firmware or a different connector pinout; a door gasket can change profile and length by build year. The part that looks identical in a photo is often the wrong revision.
That is why the serial number — not just the model — drives the order. The serial pins which revision your unit actually has, so the board reads its sensors correctly, the fan connector seats, and the gasket seals on the first visit. Guessing from the model alone is how the wrong part gets installed and a second trip gets booked. If you need help locating it, our model-number guide shows where the rating plate hides on each series.
Common genuine OEM parts we source & install
These are the parts we most often match and fit during a Sub-Zero, Wolf or Cove repair. Each is ordered to your serial, never a generic substitute.
-
Door & drawer gaskets
Magnetic gaskets are model- and serial-specific — profile, length and corner welds differ by build year. A misfit gasket lets warm air in and runs the compressor non-stop.
-
Evaporator & condenser fan motors
The fans that move cold air and shed heat. The same cabinet may have used two or three motor revisions; we match the part to your serial so the connector and RPM are correct.
-
Control, relay & power boards
Electronic control and relay boards are revised often. A board that looks identical can carry different firmware or a different pinout — exact-match matters or the unit misreads sensors.
-
Compressors & sealed-system parts
Compressors, dryers, evaporators and condensers. These are sealed-refrigerant parts — replacing them is a professional, EPA-608-certified job, never a DIY swap.
-
Thermistors & temperature sensors
The sensors the control reads to hold temperature. An out-of-spec sensor throws codes and drifts the cabinet; the resistance curve must match the exact model.
-
Water valves & ice-maker modules
Inlet valves, ice-maker modules, water-line solenoids and filters for refrigeration and ice. Flow rate and module logic vary by series, so the part is matched to the unit.
We also source hinges, shelving, lighting, igniters and relay assemblies for Wolf ranges and ovens and Cove dishwashers — matched the same way.
Sealed-system & board parts need a professional
- Compressors, dryers, evaporators and condensers hold refrigerant — by law they require an EPA-608-certified technician with recovery equipment, never a DIY swap.
- Control and relay boards involve line voltage and exact configuration; a mis-set or wrong-revision board can damage the unit.
- We will not install customer-supplied parts — sourcing the OEM part ourselves is what keeps the 365-day labor warranty valid.
- If the cabinet is warming or the panel is dead, stop and call (650) 484-4687.
How sourcing works — and what you pay
On the diagnostic visit we confirm the fault and read your model and serial. We then order the exact genuine OEM part through Bay Area distributors. Common gaskets, fans, valves and sensors are often stocked locally for a quick turnaround; less common boards or sealed-system parts can carry a short distributor lead time, which we tell you up front before you commit.
The part number is documented on your invoice so you know exactly what went in. The $89 diagnostic service call is credited toward the repair when you proceed, and the completed work — part and labor — is backed by our 365-day labor warranty. See how this fits the full Sub-Zero repair process, or how we confirm a sealed-system fault before any quote.

Parts FAQ
Do you sell Sub-Zero parts?
We are a repair service, not a parts counter — we do not sell parts over the counter or ship them. What we do is source the exact genuine OEM Sub-Zero or Wolf part matched to your model and serial number, then install it during the repair and document the part number on your invoice. That way the part is right, fitted correctly, and covered by our labor warranty.
Can I buy the part and have you install it?
We do not install customer-supplied parts. Because we warranty the repair, we source the genuine OEM component ourselves and verify it against your serial — that keeps the 365-day labor warranty valid and avoids a wrong-revision board, fan or gasket that looks identical but is not. Many no-name aftermarket parts also fail early, which would not be fair to warranty.
How do I find my model and serial number?
On Sub-Zero refrigeration the rating plate is usually behind the upper grille at the top of the unit, on the inside cabinet wall, or on a drawer frame. On Wolf ranges and ovens it is typically behind the kick panel, on the oven-door frame, or under a cooktop edge. Photograph the full plate and read us the model and serial — the serial pins the exact part revision.
Are aftermarket parts OK?
For a built-in luxury appliance we use genuine OEM parts. Aftermarket gaskets, fans, valves and especially control boards can be the wrong revision or lower quality, which causes repeat failures and false error codes on these tight-tolerance systems. Using the OEM part matched to your serial is what lets us stand behind the repair with a full labor warranty.
Why does the exact model and serial matter so much?
A single model number can span several hardware revisions over its production years — different board firmware, fan connectors, gasket profiles or sensor curves. The serial number tells us which revision your unit actually has, so the part fits and the control reads it correctly the first time. Guessing from the model alone is how the wrong part gets installed.
Do sealed-system and board parts need a professional to install?
Yes. Compressors, dryers, evaporators and condensers contain refrigerant and by law require an EPA-608-certified technician with recovery equipment — these are never a safe DIY repair. Control boards and relays also involve line voltage and exact configuration. We handle the diagnosis, sourcing and certified installation as one repair so the work is safe and warrantied.
