How to Use the Serial Number on Your GE Appliance to Determine Its Age

If you’re wondering how old your GE appliance is, you can determine its age by using the serial number. Each GE appliance has a unique serial number that contains information about the appliance, including the month and year of manufacture.

In this post, we’ll walk you through how to decode your GE appliance’s serial number to determine its age. We’ll use the examples from Eric’s video to illustrate the process.

Step 1: Locate your appliance’s model tag

Before you can decode your appliance’s serial number, you’ll need to locate its model tag. The model tag is a small metal or plastic plate that is typically located on the appliance in a safe but easy to find location. If you’re having trouble locating the tag, you can use our model number locator for common tag locations.

Step 2: Determine the month of manufacture

The first character of the serial number indicates the month in which the appliance was manufactured. Use GE’s Appliance Manufacture Date Code Chart to determine the corresponding month. For example, if the first character of your appliance’s serial number is ‘D’, it was manufactured in February.

Step 3: Determine the year of manufacture

The second character of the serial number indicates the years during which the appliance may have been manufactured. Use GE’s Appliance Manufacture Date Code Chart to determine the possible years. For example, if the second character of your appliance’s serial number is ‘R’, it could have been manufactured in 2020, 2008, 1996, 1984, 1972, or 1958.

Step 4: Use the owner’s manual to narrow down the year

To narrow down which year your appliance was manufactured, you’ll need to reference the owner’s manual. Look for a date on the bottom of the first or last page. If you don’t have a physical copy of the manual, you can find a digital version on GE’s website using your appliance’s model number.

Match up the year from the owner’s manual to the closest year in the chart. For example, if the date listed in your owner’s manual is 11-22 and the second character of your appliance’s serial number is ‘R’, the closest year in the chart is 2020. This indicates that your appliance was manufactured in February of 2020.


Let’s run through a few examples using the information from Eric’s video.

Example 1: GE Microwave

Serial Number: D S

Month: February

Possible Years: 2021, 2009, 1997, 1985, 1973, or 1959

Date Listed in Owner’s Manual: 11-08

Closest Year in Chart: 2009

This indicates that this microwave was manufactured in February of 2009.

Example 2: GE Stove

Serial Number: H A

Month: May

Possible Years: 2013, 2001, 1989, 1977, 1944

Date Listed in Owner’s Manual: 01-09

Closest Year in Chart: 2013

This indicates that this stove was manufactured in May of 2013.

Example 3: Older GE Stove

Serial Number: A H

Month: January

Possible Years: 2017, 2005, 1993, 1981, 1951

Date Listed in Owner’s Manual: 03-93

This indicates that this stove was manufactured in January of 1993.


Decoding your GE appliance’s serial number is a simple process that can help you determine its age. By using GE’s Appliance Manufacture Date Code Chart and the information from your appliance’s model tag and owner’s manual, you can easily determine when your appliance was made.

Who Made My Sears Kenmore Appliance

Kenmore is a popular appliance brand sold by Sears.  Sears does not manufacture any of the appliances themselves, instead they source that out and have other manufacturers make their appliances for them.  You can easily decode the model number of the appliance to tell you who made your Kenmore appliance.

The first three digits in a Kenmore model can will tell you who manufactured the appliance for Sears.  For example model number 110.45862400, the first three digits are 110 so that would tell you that Whirlpool manufactured the appliance.  Some of the more common appliance manufacturers Sears uses is Whirlpool, Frigidaire, LG, and GE. If you are looking for parts for your Kenmore appliance your can search for the model number in the search box at the top of the page.

Serial Number Example:
