Whirlpool WP2182181 Refrigerator Thimble

The Whirlpool WP2182181 Refrigerator Thimble is a small but important component for any Whirlpool, Kenmore, or KitchenAid refrigerator. This unsung hero ensures effective and correct drainage of defrost water, which is essential to the defrost cycle. The thimble, which is usually situated close to the evaporator coil, serves as a refrigerant channeling mechanism. A heating element dissolves ice buildup on the evaporator coil during defrost cycles. Then, the thimble is useful because it diverts the melted defrost water from the coil and into the drain pan. By doing this, the water on the coil is kept from refreezing, which would impair cooling. To preserve maximum cooling effectiveness and avoid ice dams, a functional thimble is necessary.
