How do I replace the ice making sensor on Leisure 6100?

My Leisure American Style Fridge Freezer Is Displaying Error Code E8?

The LCD Panel on the Freezer Door is Displaying Code E8. This may have somthing to do with the fact it will not dispense ice? It was working well until two weeks ago. It sounds like the motor still works but no ice comes out. I can get the part but how do I replace it?
