Where to find your appliance model number
Most appliances carry the model number on a sticker or metal plate you can see once a door, lid or drawer is open: the door edge on a dishwasher, an inside wall on a fridge, under the lid on a top loader, the door opening on a dryer. Snap a photo of the whole tag and send it with a short description of the problem before the tech comes out.
Your dishwasher is sitting full of gray water, and you've got a repair tech coming tomorrow. The one thing that most often decides whether that visit fixes it or ends with "I'll have to order that part" is a string of letters and numbers printed on a sticker you've probably never looked at. Here's where to find it on every common appliance, and what to send along with it.
Why the model number matters so much
Appliance parts are specific. The drain pump that fits one dishwasher often won't fit another from the same brand made a year later. With the model number in hand before the visit, a tech can look up the parts that commonly fail for that exact unit and bring the likely one on the truck.
Without it, the first visit is often just diagnosis. The tech finds the bad part, orders it, and comes back days later. That's a longer wait for you, and a second trip nobody really wanted. A photo of one tag can turn two visits into one.
Where to look, appliance by appliance
Manufacturers put the tag in places you can reach without tools, but not always in the obvious spot. Start with the first location listed, then work down.
| Appliance | Check first | Then try |
|---|---|---|
| Dishwasher | The edge of the door, top or side, when it's open | The side of the tub frame, or behind the lower kick plate |
| Refrigerator | An inside side wall or the ceiling of the fresh food section | Behind or under the crisper drawers; on some models, the back |
| Top-load washer | Under the lid, or on the back of the control panel | The side or back of the cabinet |
| Front-load washer | Around the door opening, on the rim or behind the door | Behind the lower access panel |
| Dryer | Inside the door opening, on the frame | The back panel near where the vent or cord connects |
| Range or oven | The frame around the oven door opening | Behind the storage or warming drawer |
| Microwave | Inside the door frame when the door is open | The back or side panel on countertop models |
Locations vary by brand and year. If the first spot comes up empty, check the next one before pulling anything away from the wall.
Safety first: don't unscrew panels, and don't drag a gas range or dryer out to read the back. The gas connection can loosen. If the tag isn't somewhere you can see with the door open, tell the shop and let the tech find it.
What the tag looks like
It's usually a white or silver sticker, sometimes a small metal plate, with a grid of small print. You're looking for a line labeled "Model," "Model No." or "MOD." It's often right next to a line labeled "Serial" or "S/N." The electrical ratings (volts, amps) are usually on the same tag, which is how you'll know you've found the right one.
Model numbers mix letters and digits, and a few characters are easy to confuse: zero and the letter O, one and the letter I, eight and B. That's the main reason a photo beats reading it over the phone.
What to send the repair shop
When you book, have these ready. It takes two minutes and saves a lot of back and forth.
- A clear photo of the whole tag. Use your phone's flash, hold it at a slight angle to avoid glare, and make sure every line is readable when you zoom in.
- What it's doing, in plain words. "Won't drain, hums for a minute, then stops" tells a tech far more than "it's broken."
- Any error code on the display. Write it down exactly, or take a photo of the screen.
- When it started and what changed. A power outage, a move, a new detergent or a load that was too big can all point to the cause.
- Rough age, if you know it. The year you bought it, or the house closing date if it came with the home.
If the shop asks for the photo by email or through a form, send it the same day you book so the tech can look it up before your appointment.
If the tag is missing or unreadable
Tags fade, peel or get scrubbed off, especially on dishwashers and inside fridges. Before you give up, check the owner's manual, the original receipt or delivery paperwork, and any product registration email from when you bought it. Many retailers also keep past purchases in your online account.
If none of that turns it up, tell the shop when you call. A tech can often identify the model from other labels inside the unit, but it may take the first visit to do it, and knowing that ahead of time sets the right expectations.
For appliance techs: make the tag photo part of every booking
Customers rarely know where the tag is, so the easiest win is to tell them. Keep the table above handy, or send this page to new customers when they book. Ask for the photo and a one-line description of the symptom before you drive out, and you'll load the truck for the likely failure instead of the whole catalog. That habit is a big part of cutting second trips for parts, and it makes your diagnostic fee easier to justify because the first visit actually fixes things.
Common questions
What's the difference between the model number and the serial number?
The model number identifies the product line and version, which is what parts are looked up by. The serial number identifies your specific unit and often encodes when it was built. They usually sit on the same tag. Send a photo of the whole tag so the tech gets both without guessing which is which.
The tag is worn off. Can the appliance still be repaired?
Usually, yes. A tech can often identify the model from other labels, a wiring diagram tucked inside a panel, or the purchase paperwork. Check your receipt, the owner's manual, or any registration email from when you bought it. It just may take a first visit to pin down, so tell the shop up front that the tag is unreadable.
Is it safe to pull the appliance out to find the tag?
Only if you can do it without straining the water line, gas line or cord, and never on a gas range or dryer if you're unsure how the connection is secured. Look inside doors and drawers first, since most tags are there. If the tag is on the back and the unit is heavy or built in, leave it for the tech.
Does my appliance's age matter for the repair?
It helps the tech give you an honest repair or replace answer. The serial number often reveals the build year, and knowing the age next to the repair price makes that conversation much clearer. Having the tag photo ready means the tech can bring that up on the first visit.
