The Pan Screw is an OEM part for Whirlpool refrigerators. It secures the crisper drawers in the refrigerator, ensuring they remain stable and properly aligned. This screw is essential for maintaining the functionality and organization of the refrigerator's storage system. Causes of a bad pan screw can include wear and tear from regular use, over-tightening, or corrosion due to moisture exposure. A damaged or missing screw can lead to the crisper drawers becoming loose or misaligned, affecting the refrigerator's storage efficiency.
