What to write down when you buy an appliance

Brand, model, serial number, purchase date and warranty end: five facts to write once, while the machine is in front of you, before its first repair.

5 min readUpdated 26 September 2026

A new appliance is delivered, plumbed in or plugged in, and working. That's the one moment its model plate is clean, legible and easy to reach. Write five things down now: the brand and model, the serial number, when it was bought and installed, and when the warranty ends.

This covers anything you plug in or plumb in, new or already in the house when you moved in. It takes about two minutes per item and it won't tell you whether an extended warranty is worth buying; that's a separate decision, covered in appliance warranties: what to track.

A checklist of five facts to record about a new appliance: brand, model, serial number, purchase and install dates, and warranty end.
The five fields to write down while the appliance is in front of you.

Example: a filled appliance record

A made-up record for a single dishwasher, not a real one.

What's worth adding for specific types

The five fields cover most things. A few categories are worth one extra line.

  • Refrigerator

    Extra worth writing down
    Water filter part number, and the replacement interval printed inside
  • Furnace or central air

    Extra worth writing down
    Filter size, and whether it's a standard 1 inch or a thicker media filter
  • Water heater

    Extra worth writing down
    Tank size in gallons, and the fuel type: gas or electric
  • Garage door opener

    Extra worth writing down
    Remote or keypad type, not the code itself
  • Dishwasher, range, microwave

    Extra worth writing down
    Nothing extra; the standard five fields cover it

Where the plate usually hides

It's almost never on the front. Refrigerators hide it inside, near the crisper drawers or on a side wall; washing machines keep it around the door opening; dishwashers put it on the edge of the door, visible only when the door is open.

The full list by appliance type, plus what to do when the label has worn away, is in how to find the model number on any appliance.

Photograph the plate, then type the model number too

A model number is long and mixes letters and digits in ways that are easy to mistype in bad light. A photo of the plate takes a second and is always accurate.

Type the model number somewhere searchable as well, because a photo buried in three years of camera roll isn't findable the day you actually need it.

Check for a recall while you're at it

Recalls are the item on this list people are least likely to check again once the record is written. Manufacturers issue them for real hazards, from a washer's fire risk to a dishwasher's wiring, and the U.S. Consumer Product Safety Commission's recall listings are searchable by brand or product type without registering anything first.

Registering a new appliance isn't required for any of this, but it does get you a direct notice if the model is recalled later. If you'd rather skip the marketing emails, subscribing to CPSC's recall alerts does the same job without registering a single product.

When the record is missing entirely

Sometimes the plate itself is gone: steam, degreaser or a cabinet reface can wear a sticker past reading. Check the installation manual first, if you kept it, or look for a second plate inside a door or access panel, which sometimes survives longer than the exterior sticker.

For an appliance that came with the house and has no paperwork at all, bought or inherited a house with no records covers how to work out roughly how old something is and what to check first.

Questions about appliance records

Why does the serial number matter if I already have the model number?

A model number tells a parts supplier which part fits your appliance. A serial number identifies the specific unit and its manufacturing date, which is what a warranty claim or a recall search actually needs. Keep both written down; they answer different questions and a claim can need either one.

Where is the serial number on a refrigerator, washer, or dryer?

On most refrigerators it's on a plate inside, near the crisper drawers or on a side wall. On washers and dryers it's usually inside the door frame or on the back panel. The exact spot varies by brand and model, covered type by type in how to find the model number on any appliance.

Do I need to register a new appliance?

No. A warranty claim doesn't depend on registration since the receipt and serial number are enough on their own. Registering mainly gets you a direct notice if the model is recalled later, which you can also get by subscribing to the CPSC's recall emails, no product registration required.

What if the model number label is worn away or missing?

Check the installation manual or the original box if you kept either one. Some appliances carry a second plate inside a door or access panel that survives better than the exterior sticker. As a last resort, a parts retailer can sometimes identify a unit from photos of its features and dimensions.

What Home Base does with these fields

Home Base has fields for brand, model, purchase date, install date and warranty end, plus a Notes field where a serial number, a filter part number, or anything else can go, since there's no dedicated serial field. It shows the fields that make sense for the category, so a water heater and a garage door opener aren't asked the same six questions.
