TAPPAN serial numbers typically include a series of letters and numbers that can be used to identify the manufacturing date, model number, type of appliance, and other important information about the appliance. Here are the steps to decode a TAPPAN serial number:
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
TAPPAN serial numbers typically follow a universal convention:
- 10 digits consisting of letters and numbers. If its an HVAC unit, look for a 12 digit number and the first digit should always be an alpha character.
- The third character of the serial number should be numerical regardless of the length of the TAPPAN serial number.
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:
- The second character of the serial number denotes the type of appliance. Refer to public code charts for a full breakdown.
- The third character correlates to the last digit of the manufacturing year. The decade is not included which makes it difficult to fully determine the age.
- The fourth and fifth characters of a TAPPAN serial number contain the week of manufacture.
