To Replace the Evaporator:

(Assuming all the steps for removal of the thrust bearing, breaker, auger, and water seal have been performed.)

1.Discharge the refrigerant from the ice maker.

2.Unsweat the refrigerant connections:

a)At the thermostatic expansion valve outlet.

CAUTION

To Reassemble the Evaporator and Auger

1.After the gearmotor has been inspected, fasten the evaporator to the gear motor, be sure that the number of shims indicated on the gear case cover is in place between the gearcase cover and the drip pan gasket. Torque the bolts to 110 inch pounds.

2.Lower the auger into the evaporator barrel, slightly turning it to match up with the drive end. Do Not Drop Into the Evaporator.

3.Complete the reassembly by reversing the disassembly for the breaker & thrust bearing assembly.

For Access to the Evaporator to Gearmotor bolts:

1.Remove upper front and top panels.

2.Remove screws holding control box assembly to the cabinet, move the control box out of the way, temporarily secure to cabinet.

3.Remove the upper half of the ice chute.

4.Remove the ice sweep.

5.Loosen clamp under ice chute, and remove the lower half of the ice chute.

6.Remove the 2 screws securing the front portion of the gearmotor support to the cabinet
