Abstract
A dryer appliance including a slide bearing assembly mounted to a top bearing for supporting a rotating drum and including a wear indication device is provided. The slide bearing assembly includes a contact circuit including two electrical leads positioned on a top bearing of the dryer appliance. A slide bearing is positioned over the contact circuit for supporting a drum during rotation and maintaining an open circuit between the two electrical leads. A controller monitors the resistance across the two electrical leads, determines that a slide bearing failure has occurred when the resistance drops (e.g., due to worn slide bearings), and notifies the user accordingly.
