How to Find Your Sub-Zero Model and Serial Number
Step-by-step guide to locating the model and serial number on Sub-Zero refrigerators, freezers, and wine storage units. Essential for ordering the correct replacement parts.
Why You Need Both Numbers
Sub-Zero appliances can use different parts depending on the production range. Two refrigerators with the same model number may require different gaskets, compressors, or ice makers depending on when they were built. The serial number tells you which production range your unit falls into.
Before ordering any replacement part, locate both the model number and the serial number. Having both numbers reduces the risk of ordering a part that looks similar but does not fit.
Where to Look on Refrigerators and Freezers
On most Sub-Zero refrigerator and freezer units, the rating plate is located inside the unit, typically on the left interior wall near the top. Open the main door and look at the upper left side panel. The plate is a small metal or adhesive label printed with the model number, serial number, and manufacturing date.
For built-in models (700 series, 600 series), the plate may be on the interior wall behind the lower drawer or on the ceiling of the compartment. If the label is worn or faded, use a flashlight at an angle to read the embossed or printed characters.
Tips
- •Write down both numbers exactly as they appear, including any letters or dashes.
- •Take a photo of the rating plate with your phone so you have it for reference.
- •If the label is missing, check your original purchase documentation or warranty card.
Where to Look on Wine Storage Units
Sub-Zero wine storage units typically have the rating plate on the interior wall, often behind the lower shelf or near the bottom of the compartment. Open the door and look at the left interior wall toward the bottom.
Some older wine models place the plate on the back of the unit near the compressor. If you cannot find it inside, carefully pull the unit forward and check the rear panel.
Understanding Serial Number Date Codes
Sub-Zero serial numbers often encode the manufacture date. For many models, the serial number starts with a letter followed by digits. The first several digits can indicate the production year and week. For example, a serial starting with "181" typically indicates production around 2018.
When a part listing says "starting with serial #1810000," it means only units produced from that serial number onward use that specific part. Earlier units may require a different part number.
Tips
- •If a part listing mentions a serial number cutoff, compare it carefully to your unit's serial.
- •When in doubt, send both numbers through the Check Fit form and our team will verify compatibility.
What to Do If the Label Is Missing
If the rating plate is missing or unreadable, you can still get help. Take clear photos of the appliance, including the control panel, door handle style, and any visible markings. Note the approximate age and any previous part numbers you can find on existing components.
Submit these details through our Part Finder form and our team will help narrow down the correct parts for your unit.
