That does seem to be where it fell from. I cant find any spot that looks like the clip was from. No shiny spot from friction…no notch it would fit into. I might just be taking the other side off in the morning. Maybe its just a spacer to keep the actuator a specific distance from the baking plate. If it slipped over the protruding cable that may make sense.
Maybe Db 4690 will come on in the morning.
