How to find your appliance's model number (and why it matters)

Almost every warranty claim, parts lookup, or service request starts with the same question: what's the model number?

It's the most basic data point about an appliance, and it's the one homeowners can never find in the moment they need it. Manufacturers put model plates in inconsistent, unobvious places. The plates fade over time. Sometimes the plate is gone entirely. And until you need it — to order a replacement filter, to file a warranty claim, to look up the manual — you don't know that finding it takes 15 minutes when it shouldn't take 30 seconds.

Here's where the model plate is on every major appliance, plus what to do when you can't find it.

What you're looking for

Most appliances have two important numbers on a small metal or plastic plate:

• Model number — the big alphanumeric string (like MDB4949SDM3 or DW80M9550UG/AA). This identifies the specific product and is what parts sites and manufacturer lookups need.
• Serial number — a separate string near the model number, identifying this specific unit. Manufacturers use this for warranty registration and to confirm date of manufacture.

Both are on the same plate. The plate also usually has the manufacture date, electrical specs, and certification marks (UL, ETL, ENERGY STAR, etc.).

You usually need the model number for parts lookup and the model + serial for warranty claims.

Where to look, by appliance

Dishwasher

• Most common: inside the door frame. Open the door. Look at the metal frame around the tub opening — on the left or right side of the inner door, sometimes along the top. The plate is usually visible without removing anything.
• Sometimes: along the bottom front kick plate. Pop the kick plate off (usually 2-4 screws or snap-on clips). Plate may be on the inside of the kick plate or on the dishwasher chassis behind it.
• Older models: top of the door, visible when door is closed. A label that wraps from inside the door over the top edge.

Refrigerator

• Top-mount and side-by-side: inside the fresh-food compartment. Open the main fridge door. Look on the side walls (left or right), the ceiling of the compartment, or behind the bottom drawer (pull the drawer out). The plate is usually 2-3 inches square.
• French door: behind the bottom drawer or inside the freezer drawer. Pull the bottom drawer out fully to see the plate at the back of the compartment.
• Built-in refrigerators: under the kick plate at the bottom front. Same as dishwashers — pop the kick plate.

Washing machine

• Front loader: inside the door, on the boot (rubber gasket) frame or on the right side of the inner door rim.
• Top loader: under the lid, around the rim of the wash basket or on the back panel behind the control console.

Dryer

• Front loader: inside the door frame (similar to a washer).
• Top-control models: behind the lint trap. Remove the lint screen and look down into the slot — sometimes the plate is visible at the back of the slot.
• Back panel: on the metal back of the dryer (only accessible by pulling the dryer away from the wall — last resort).

Range / oven / cooktop

• Range with storage drawer: inside the storage drawer at the bottom. Pull the drawer out fully; plate is on the front of the chassis below the oven cavity.
• Wall oven: inside the oven door frame or on the left/right edge of the door itself.
• Cooktop only: usually inaccessible without removing the cooktop from the counter. Manufacturer customer service can often look up the model from the serial number on the original purchase receipt, OR you can sometimes find it on a sticker on the underside if you have access from below (cabinet, basement).

Microwave

• Inside the door frame or on the back panel.
• Over-the-range microwaves: inside the cavity, on the bottom or rear wall.

Water heater

• Tank water heater: on the front of the tank, near the top or the control panel. A large data plate with all the specs — model, serial, capacity, energy info.
• Tankless: on the front of the unit, usually just below the display.

HVAC (furnace + outdoor condenser)

• Furnace: on the inside of the front access panel (pop the panel off; plate is on the inner face). Sometimes on the side of the burner compartment.
• Outdoor AC condenser: on the side of the unit, usually facing the house. Look for a black-and-silver metal plate, ~3x4 inches.
• Heat pump: same locations as condenser.

Garage door opener

• On the back of the motor unit, facing the ceiling. You may need a stepladder. Sometimes also on the underside of the motor housing.

Smaller / less common

• Garbage disposal: under the sink, on the side of the unit facing the cabinet wall. Often partially hidden by plumbing.
• Water softener / filtration system: on the side of the tank, near the control valve at the top.
• Pool equipment, sump pumps, well pumps: usually on the side of the motor housing or on a separate metal label affixed to the chassis.

What to do when the plate is missing or unreadable

This happens more often than you'd expect. Two main reasons: (1) the plate is in a heat-affected area and the printing fades over years, or (2) it was peeled off during a prior repair or never installed.

Recovery options:

1. Check the manufacturer's date code on other components. Most appliances have a compressor or motor with its own date sticker. The compressor's manufacture date isn't the appliance's, but it narrows the model range to a 6-12 month window.
2. UPC barcode on the box or original receipt. If you have the original purchase paperwork (or can pull it from your retailer's order history — see the warranty-lookup guide), the UPC encodes the specific model.
3. Manufacturer database lookup by serial number alone. If the model plate is gone but the appliance is registered to your address from purchase or installation, manufacturer customer service can look up the model from the serial number or your purchase record.
4. For very old appliances: if the serial number indicates a manufacture date over 15 years ago and the model is genuinely unrecoverable, parts compatibility is the more important question. A good parts site (RepairClinic, Sears Parts Direct) can identify the part by physical specifications and dimensions when model-based lookup fails.

Once you find it: photograph it

The model and serial plate is the single most important photograph you'll take of any appliance. Take it at install time, or take it now while you're already looking.

What to photograph:

• The full plate, sharp focus, all text legible
• Include the make/manufacturer (sometimes embossed separately from the model number)
• Capture the manufacture date if shown

Where to put it:

• Album/folder in your photos app dedicated to home appliance records
• An email to yourself titled [appliance type] model plate - [year installed]
• Vellum (forward the photo to your private Vellum inbox; we extract the model + serial + date automatically and surface them when you ask about that appliance)

The 30 seconds you spend photographing the plate at install time saves an hour two years later when something needs fixing.

Vellum keeps every appliance's model number, serial number, install date, and manual together in one place. Forward a photo of the plate and we extract everything; ask Vellum what dishwasher you have and you get the answer in two seconds instead of crouching at the kitchen sink with a flashlight.
