The damper opens and closes automatically depending on temperature conditions to maintain proper cooling levels. Causes of a bad damper can include seal failure allowing air leaks over time, restricted movement from mineral deposits binding internal parts, or physical damage bending critical damper components. Symptoms of a bad damper include: Inability to achieve recommended temperature settings Areas inside the fridge feeling warmer than others Fluctuating temperatures requiring frequent adjustments This Frigidaire OEM replacement part is also compatible with Electrolux, Gibson, Kelvinator, and some Kenmore models.5303918899 (AP7217243) replaces 241518501, 7241518501.
