HAIER purchased the appliances wing of GE in 2016. Since then, HAIER appliances have moved to the GE standard. You can tell from
which era your appliance is by checking if the serial number is 8-9 characters in length which is the GE standard, or a string of 18-20 characters
which was the Haier standard prior to the acquisition.
Step 1: Locate the Serial Number
The serial number is usually located on a metal plate or sticker somewhere on the appliance.
The location of the serial number may vary depending on the type of appliance you are working with. Some common places to look for the serial number include:
- On the back or side of a refrigerator
- On the rim or base of a dishwasher
- On the door jamb or control panel of a washing machine or dryer
- On the control panel of an oven or range
Step 2: Identify the Serial Number Format
HAIER serial numbers may use several different formats, depending on the age and whether is was produced before or after the GE appliance acquisition.
- Two letters followed by six digits followed by an optional letter: This format is the current GE standard which Haier is moving to. It includes additional information about the appliance, such as the model number and revision code. The first two letters represent the manufacturing plant, the next six digits represent the production date, and the final letter represents the revision code.
- Prior to the GE acquisition, a format of 18-20 digit string of characters consisting of both letters and numbers.
Step 3: Decode the Serial Number
Once you have identified the format of the serial number, you can use the following table to decode the information:
- For two letters followed by six digits followed by a an optional letter: The first two letters represent the manufacturing plant, the next six digits represent the production date, and the final letter represents the revision code. For example, a serial number starting with "RG527327B" would indicate that the appliance was manufactured at the plant in LaFayette, Georgia in February 2005 (52=2005, 7=February), with a revision code of B.
- For 18-20 character length serial numbers, the character in the 14th position represents the year code. The 15th digit represent the month code. Once you have determined the appropriate characters,
you can cross reference publicly available date charts to see which year and month your letter codes correspond to.
