Every refrigerator, dishwasher, washer, dryer, oven, and water heater has an appliance model number hiding somewhere on it — and once you know where to look, finding it takes about thirty seconds. This guide shows you exactly where the model number is located on every major home appliance, how it's different from the serial number, how to read what the digits actually mean, and what to do if the label is faded, painted over, or missing entirely.
Whether you're ordering a replacement part, booking a repair technician, filing a warranty claim, checking for a recall, or just trying to find the right owner's manual, the appliance model number is the one piece of information that makes the whole process faster and more accurate. Skip the guesswork — jump to your appliance below.
Why the Appliance Model Number Matters
A model number identifies the exact version of a product you own, down to the specific configuration, color, and production run. This matters more than most people expect:
- Parts Accuracy: Replacement parts vary between model years and revisions, even within the same product line.
- Access to Documentation: Manuals, wiring diagrams, and troubleshooting guides are indexed by model number.
- Warranty & Recalls: Manufacturers require the model and serial number for all claims and safety lookups.
- Service Efficiency: Repair technicians can't quote a price or diagnose a problem accurately without the specific model ID.
- Used Appliances: The model number allows you to verify the age and remaining warranty before you commit to a purchase.
Model Number vs. Serial Number: What's the Difference?

General Places to Check on Any Appliance
Before going appliance-by-appliance, these are the most common hiding spots across nearly every brand and category:
- Door Assemblies: Inside the door or along the door frame.
- Hidden Panels: Behind the toe-kick panel at the bottom front of the unit.
- Exterior Casings: The back or side panels of freestanding appliances.
- Underneath: The base of the unit (often for cooktops or small appliances).
- Documentation: The owner’s manual, original receipt, or the original packaging.
- Digital Records: The manufacturer's mobile app or your online account profile.
