@sissy31454, please add a picture of the part you're puzzling over so we can get an idea of what it is or does. Otherwise the only help you're likely to get is if someone on here happens to have the exact same machine as you and has disassembled it to where they've seen a white part that's likely to be what you're looking at. Odds are kinda low for that scenario, so let's see a picture instead, okay?
