How to Find Your Appliance's Model and Serial Number

The model number identifies the specific version of the appliance (its features, dimensions, and design generation), while the serial number identifies that individual unit, often encoding its manufacture date. Together, they let a technician:

• Confirm the correct replacement parts for your exact appliance, since even appliances that look identical can use different components across model years or minor design revisions.
• Look up manufacturer specifications and service bulletins relevant to that specific model, which can speed up diagnosis for known issues.
• Estimate the appliance’s age from the serial number, which is useful context for the repair-vs-replace decision if that becomes relevant.
• Order a part in advance of a visit, in some cases, if the failure and needed part can be reasonably anticipated from your description of the symptom.

Having this information ready doesn’t replace an in-person diagnosis, but it removes one common source of delay — a technician arriving without confirmed parts availability for your specific model. It’s especially useful for appliances where similar-looking models can have meaningfully different internal components across production years, since two refrigerators that look identical from the outside can still use entirely different door gaskets, water inlet valves, or control boards depending on when they were manufactured.

Refrigerator data plates are typically found in one of these locations, depending on brand and model:

• Inside the fresh-food compartment, along the upper side wall or the back wall, sometimes partially hidden behind a shelf or crisper drawer.
• Along the door frame, visible when the door is open, near the top or side edge.
• Behind the kick plate or grille at the bottom front of the unit, on some models, requiring the grille to be removed or opened.

If you can’t locate it in these spots, check your refrigerator’s original owner’s manual (many manufacturers also publish manuals online, searchable by brand), which often includes a diagram showing the exact plate location for your specific model line. French-door and side-by-side models sometimes place the plate differently than a traditional top-freezer layout, so if you’re used to one configuration from a previous refrigerator, it’s worth checking more than one likely spot before concluding the plate is missing.

Washing machine data plates are commonly found:

• Around the door opening on front-load washers, often on the frame just behind or beside the door hinge.
• Under the lid on many top-load washers, along the rim of the tub opening.
• On the back panel of the machine, near the top or bottom edge, which may require pulling the machine slightly away from the wall to read clearly.

Dishwasher data plates can be some of the harder ones to find, since the plate is often placed to be visible only when the unit is open or partially pulled out:

• On the side panel, visible when the dishwasher door is fully open — check both the left and right inner edges of the door frame area.
• On the top edge of the door itself, visible when the door is open and you look at the top rim.
• Behind the lower kick plate, on some built-in models, which may need to be removed to view the plate.

Since Oven Repair, Stove Repair, and Cooktop Repair are separate services covering different equipment, it’s worth checking the plate on the specific unit you’re having serviced:

• Wall ovens: typically along the side of the oven frame, visible when the oven door is open, or sometimes on the top or bottom edge of the frame.
• Freestanding ranges (combination stove and oven in one unit): commonly found by opening the oven door and checking the frame, or along the back top edge behind the control panel, or inside the storage drawer at the bottom of the unit if present.
• Cooktops: often located on the underside of the cooktop, which may require accessing it from below (through a cabinet underneath, if installed over one) rather than from the top surface.

For Convection Microwave Repair, the data plate is commonly found:

• Inside the door frame, along the edge visible when the door is open.
• On the side or back panel, for countertop models, sometimes requiring the microwave to be pulled slightly away from the wall.
• Inside the cabinet mounting area, for over-the-range or built-in models, which may require lowering or partially removing the unit to view — if it’s not visible without that step, checking the installation manual (often included with the unit or available from the manufacturer) is a safer first step than attempting removal yourself.

• Standalone freezers: similar to refrigerators — check the interior wall near the top, the door frame, or behind a lower grille panel. Chest freezers often have the plate on the inside of the lid or along an upper interior wall.
• Built-in or under-counter ice makers: typically on the side panel, visible when any front kick panel or door is opened, or occasionally on the back panel if the unit can be safely and easily pulled out.
• Refrigerator ice maker modules specifically (as opposed to the refrigerator’s own data plate): these are usually a separate, smaller part number found directly on the ice maker module itself inside the freezer compartment, distinct from the refrigerator’s main data plate elsewhere on the unit.

A few numbers commonly found on or near an appliance are not the model or serial number, and providing the wrong one can cause confusion or delay when ordering parts:

• UL/safety certification numbers or logos, which relate to safety testing standards, not the specific model.
• A barcode or QR code without an adjacent printed model/serial number, which may be an inventory or manufacturing code rather than the customer-facing model identifier.
• The manufacturer’s general company information (name, address, customer service number) printed on the same plate, which is separate from the model and serial fields specifically.
• A part number found on an individual internal component (like a specific control board or motor), which identifies that component, not the overall appliance.

If a plate has multiple number fields, look specifically for ones labeled “Model No.,” “Model,” “MOD,” “Serial No.,” “Serial,” or “S/N” — these labels are fairly consistent across most major manufacturers even when plate layouts, fonts, and overall design differ quite a bit from brand to brand.

Once you’ve located the data plate, taking a clear photo is often more reliable than copying the numbers down by hand, especially for long alphanumeric strings that are easy to mistype.

Reasonable photos to take:

• A clear, well-lit, close-up photo of the full data plate, including the model and serial number fields and the manufacturer name.
• A wider photo of the appliance itself, which can help confirm the general type/configuration (side-by-side versus French door refrigerator, for example) even if the plate photo is slightly unclear.
• A photo of the specific symptom area, if relevant and safe to photograph (a visibly damaged element, a leak location, a display screen showing an error code), which can give a technician useful context ahead of the visit.

Having these ready when you call or schedule can streamline the initial conversation, even though an in-person diagnosis is still how the actual cause gets confirmed — think of them as useful preparation that speeds up the process, not a substitute for a technician actually seeing the appliance.

Model and serial numbers are the most useful single piece of information to have ready, but a few additional details round out a complete picture for a technician:

• Approximate purchase or installation date, if you don’t have an exact one, which helps estimate the appliance’s age alongside anything the serial number reveals.
• Any prior repair history on the specific appliance, including roughly when and what was done, if you know.
• A clear description of the current symptom — what’s happening, when it started, and any sounds, smells, or error codes involved.
• Whether the appliance is built-in or freestanding, and any notable installation details (a tight closet, a stacked laundry configuration, an under-counter dishwasher), since these can affect access and labor time as discussed in our appliance repair cost guide.
• Whether you have the original owner’s manual, even if just a digital copy, since it can sometimes answer a technician’s question on the spot without needing to look anything up separately.

Gathering this information takes only a few minutes and can make both the scheduling conversation and the actual service visit more efficient, since less time during the visit itself is spent on information-gathering that could have been prepared in advance.

A few patterns come up often enough to be worth mentioning directly:

• Copying only part of a long alphanumeric string. Model and serial numbers can run 10-20+ characters including letters, numbers, and sometimes hyphens — it’s easy to accidentally truncate or mistype part of a long string when copying it by hand, which is one reason a photo is often more reliable.
• Confusing a “series” or marketing name with the actual model number. Manufacturers often market appliances under a collection or series name (visible on a sales sticker or in advertising) that isn’t the same as the specific model number printed on the data plate itself.
• Reading a warranty extension or protection-plan number instead of the appliance’s own model/serial. Paperwork from an extended warranty or protection plan sometimes includes its own reference numbers, which are separate from the manufacturer’s model and serial number.
• Providing a number from a different but similar appliance, in households with more than one unit of the same type (a garage freezer and a kitchen freezer, for example) — double-checking which specific unit you’re photographing avoids this mix-up.
