REMOVAL AND REPLACEMENT: Auger

Hazardous Moving

Parts.

Moving auger can cause personal injury. Disconnect electrical power before beginning.

To Remove the Auger:

Turn off the water to the machine, and unclip the evaporator drain hose, pull it down and drain the evaporator into the bin or a container.

1.The top panel must be removed.

2.Remove bail clip and remove ice chute cover.

3.Unscrew ice sweep.

4.Remove ice chute body.

5.The auger and breaker/bearing may now be removed as an assembly.

e. If the auger is stuck use a slide hammer type puller to pull on the auger at the threaded hole. The size of that hole is 5/8"-18.

Inspect the auger, the critical areas of the auger are:

1.The auger body. It should be clean and shining. Sometimes an auger will appear clean when wet, but after it is dry it will be seen to be stained. Scrub the auger with ice machine cleaner and hot water.

Ice machine cleaner is an acid. Handle it with extreme care, keep out of the reach of children.

2.The water seal area. Because the auger has been removed, the water seal will have to be replaced. Remove the water seal top half from the auger, and inspect the auger for minerals clean as required.
