The Door Hinge Pin is an OEM part for Frigidaire refrigerators. It is responsible for supporting the mullion or flapper, which is the vertical strip that divides the refrigerator doors. It provides smooth movement and proper alignment of the mullion, allowing it to pivot easily for access to both compartments while maintaining an airtight seal when closed. Causes of a bad hinge pin can include wear and tear over time, accidental damage, or improper handling. A damaged or worn-out hinge pin may result in difficulties in opening or closing the mullion. Symptoms of a bad Hinge Pin include: Difficulty in opening or closing the doors Excessive play or wobbling of the mullion Failure to maintain a proper seal between door Unusual noises during use This OEM Frigidaire part can also be used on select Electrolux, Frigidaire, Gibson, Kelvinator, Westinghouse, and Sears/Kenmore models.241779401 (AP4393564) replaces 1512662, 7241779401, AH2358752, EA2358752, PS2358752.
