This refrigerator is 9 years old and I think the defrost fan is going bad. It’s starting to make a higher pitched fast chirping noise intermittently when it’s on. I opened up a panel from inside the freezer and got access to it and if feel like maybe the shaft/blade connection may be wearing out and causing the noise…? At any rate, I need to figure out what part I need and how to repair it. Thanks!

Part 610 is the evaporator motor.
