Snap disc #2 is also located on the back side of the feed drop
tube. There are 2 orange wires connected to it. This snap disc

Snap disc #3 is mounted on the back of the auger tube in the
center of the appliance and has a reset button. To access
it remove the right side panel. If the fi re tries to burn back
