KSRS271kss01 Superba Ice Crusher motor replacement

KSRS271kss01 Superba is what is on the fridge. Ice grinder turns by hand and 3 prong attachment is good. Motor will not turn when all switches depressed. I bought a new motor, but now the mystery is how to disassemble the door. I removed every screw I could find from the outside and inside, and plastic parts still appear to be glued and/or snapped into place. ANY CLUE to tell me where to get access (inside or out) and where to apply leverage to plastic parts that won't break them? I can't be sure if I go at it from the outside or inside. I'm guessing from the outside.
