Refrigerator gasket seal worn, icemaker tray cracked in several locations. Ordered the above two parts to replace existing parts. I was told that, based on my units age, I would need the assembly case lock. That proved to be inaccurate. The new assembly case lock was in fact not required. The assembly tray ice unit fit exactly like the previous unit and functions correctly. The gasket assembly unit also fit perfectly into the refrigerator door. Overall, I am very pleased with the order from the appliance parts pros company and would highly recommend their company to any homeowner. Additionally, I should mention that the package was extremely well packed in shipment and arrived with no damage to any of these enclosed parts.
