Model Number Finder & Decoder in Slatington, PA
Where to find the model and serial number on each appliance, and how to read the age and type from it.
Refrigerator
Inside the fresh-food section on a side wall, the ceiling, or behind the crisper drawers. On some models it is on the frame behind the kick plate.
Freezer
Inside on a side wall or the back of the lid on chest freezers; on the back of the cabinet on some uprights.
Washing machine
Front-load: inside the door frame or behind the filter door. Top-load: under the lid or on the back of the control panel.
Dryer
Inside the door frame, on the back of the cabinet or behind the lint screen.
Dishwasher
On the edge of the door or the tub frame, visible when the door is open.
Oven / range
Behind the storage drawer or on the frame behind the oven door. Wall ovens: on the side trim when the door is open.
Microwave
Inside the door frame or on the back. Over-the-range models often have it behind the door on the left.
Range hood
Behind the grease filters inside the hood.
Water heater
On the large label on the side of the tank.
Reading the Label
- The model number identifies the product line and features. The serial number identifies your exact unit and often encodes the build date.
- Write both down exactly, including dashes and letters. 0 (zero) and O (letter), 1 and I are a common mix-up.
- Take a photo of the label with your phone: it is the easiest way to share it with a technician.
Finding the Manufacture Date
Many brands encode the build date in the serial number. These patterns cover many models but not all, so confirm with the manufacturer if it matters (for example for a warranty claim).
| Brand | Typical serial number date pattern |
|---|---|
| Whirlpool, Maytag, KitchenAid, Amana | In many serial numbers the second letter is the year code and the next two digits are the week. Whirlpool publishes the year letters in its service literature. |
| GE, Hotpoint | The first two letters of the serial number usually encode month and year: the first letter is the month and the second the year, from a repeating letter table. |
| Samsung | In many 15-character serial numbers the 8th character is the year and the 9th the month. |
| LG | The first digit of the serial number is usually the last digit of the year, and the next two digits are the month. |
| Frigidaire, Electrolux | The 3rd digit is often the last digit of the year and the 4th and 5th are the week. |
| Bosch, Thermador | The FD number on the label encodes the production date: the first two digits are years since 1920 and the next two are the month. |
