Its kind of difficult to provide you with a defintive solution with no illustration or model number. However, if this is a Kenmore dryer, it is manufactured by Whirlpool. The date of manufacture for Whirlpool appliances is detemined by the SERIAL NUMBER. The following link explains:
The serial number will be located on a nameplate around the door opening along with your MODEL NUMBER.
The second digit in the SERIAL NUMBER identifies the YEAR it was manufactured. The two numbers that follow the second digit, represent the WEEK (52 weks in a year) it was manufactured.
