Hi, I haven't been here for years. But now I need your help again! My Whirlpool Sidekicks have been installed for 8-9 years. Now the refrigerator has died. I'm kind of stuck getting a new Sidekick since that is how my kitchen is designed. However, the new style doesn't match my existing Sidekick Freezer. Does anyone know if the doors are interchangeable so I can put my existing door on the new unit? TIA!
