3.Removal and Replacement of Auger

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

2)Close the water supply line shut-off valve.

3)Remove all ice from the storage bin.

4)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.

5)Remove the top panel.

6)Remove the spout.

7)Remove the upper rear panel. See Fig. 12.

8)Remove the clamp securing the drain plug, then lower the drain hose into a container. Remove the drain plug to drain the water from the reservoir and evaporator assembly.

9)After all of the water has drained, replace the drain hose, drain plug, and drain clamp in their original positions.

10)Remove the packing.

11)Remove the socket head cap screws securing the extruding head and evaporator flange. Remove the evaporator flange, then grasp the cutter and carefully lift out the cutter and extruding head. Grasp the top of the auger and carefully lift out the auger.

12)When pulling out the auger, the upper part of the mechanical seal should come out with it. The mechanical seal consists of two parts. One moves along with the auger, and the other is fixed on the lower housing. Inspect the part of the mechanical seal that came out with the auger. If the contact surface on the bottom of the seal is worn, cracked

or scratched, the mechanical seal may cause water leaks and both the upper and lower parts of the mechanical seal should be replaced. Instructions for removing the mechanical seal are located later in this procedure.

13)Remove the mechanical seal from the old auger and place it on the new auger.

14)Install the new auger. Replace the cutter, extruding head, and evaporator flange in their correct positions.

15)Open the water supply line shut-off valve and check for water leaks.

16)Plug the unit into the electrical outlet, then move the power switch to the "ON" position.

17)Allow the icemaker to operate until the gear motor starts. Check for water leaks.

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

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

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