1. Upper Bearing Wear Check

To ensure that the bearing inside the extruding head does not exceed the wear tolerance of .02", follow the instructions below.

1)Move the power switch to the "OFF" position, then unplug the unit from the electrical outlet.

2)Remove all ice from the storage bin.

3)While maintaining a hold on the door, remove the hinge stop pin from hinge (B). Pull out the bottom of the door slightly, then gently remove the door from hinge (A). See Fig. 10.

4)Remove the top panel.

5)Remove the spout.

7) Grasp the top of the auger and move the auger towards you and then try to insert a

.02" round stock or pin gauge in between

the back side of the auger shaft and the bearing surface. See Fig. 11. Check several

locations around the auger shaft. If the gauge goes between the shaft and the bearing at any point or if the bearing is scratched or cracked, both the top bearing

in the extruding head and the lower bearing in the housing should be replaced. Instructions for removing the extruding

head and housing are located later in this procedure.

Note: Replacing the bearing requires a bearing press adaptor. If one is not available, replace the entire extruding head and housing.

8)Replace the removed parts and panels in the reverse order of which they were removed.

9)Plug the unit into the electrical outlet, then move the power switch to the "ON" position to start the automatic icemaking process.
