Whirlpool WCN 9-1 Freezer Door Seal
The purpose of this replacement Door Seal is to ensure that your freezer has an air-tight seal at the door, which helps to keep the cool air in and prevent warmer air from entering.
It helps to limit the amount of moisture which is able to get into the freezer, controlling ice buildup. If you notice your existing seal is cracking, then replacing it will protect your food while conserving energy.
