How to Find a Manufacturing Date for Appliances

If you're going to buy or sell an appliance, or dispose of one, you'll need to find a manufacturing date for it. For appliance disposal, you'll need to know the manufacturing date for refrigerators and freezers in particular because of the refrigerants they contain. If they were manufactured prior to 1995, they commonly contain ozone-damaging chlorofluorocarbon (CFC).

Step 1

Locate the model and serial number label on the appliance. Look on the back of a washer or dryer for the paper label. On a freezer or refrigerator, the label may be located on the inside, either on the liner or on the side of the door.

Step 2

Check the model and serial number label for the manufacturing date. If there is no date, write down the model and serial numbers. They will likely be a combination of numbers and letters.

Step 3

Visit the Appliance Age Finder website (see Resources) to find manufacturing dates for Whirlpool, KitchenAid, Roper, Estate and Heritage Maytag appliances. Type in the serial number and hit the "Calculate" button to find the answer. For Whirlpool appliances, visit the Appliance Aid website (see Resources) and use their Whirlpool appliance date finder.

Step 4

Visit the Appliance 411 website and use its date code search. This site helps find a manufacturing date for appliances that were made after the 1970s or 1980s. It doesn't provide the dates for stoves, refrigerators, washers, dryers or freezers that are considered to be antiques. Use the drop-down menu to select the brand, appliance type and your location. Then key in the model number and the serial number. Click on the "Date It!" button to find the manufacturing date.

Step 5

Locate the customer service number or email address for the maker of the appliance. Look in the owner's manual or use the Anywho free phone directory (see Resources). Have the model number and serial number of the appliance handy. Call or email the company to find a manufacturing date for the appliance.
