This Avantco 17818961 right hinged door assembly is a direct replacement for the one that came standard on black and white GDC-15 series units. The door is a vital part of your unit, allowing a tight seal that locks in cold air while still providing a clear view of the unit's interior. If the door is not closing properly, and replacing individual components is not an option, this part will give you a whole new door to ensure optimal performance.
