8)Reconnect the black float switch connector to the control board BLACK K5 connector, then replace the control box cover in its correct position.

9)Move the control switch to the "ICE" position. Replace the insulation panel and the front panel in their correct positions, then turn on the power supply. After 1 minute, the 1-minute fill cycle should end and the initial harvest cycle should begin. If the initial harvest cycle begins, the float switch is good and the check is complete. If the initial harvest cycle does not begin, continue to step 10.

10)Turn off the power supply.

11)Remove the front panel.

12)Move the control switch to the "OFF" position.

13)Remove the control box cover.

14)Disconnect the black float switch connector from the control board BLACK K5 connector.

15)Check for continuity across the float switch leads. With the water tank full, the float switch should be closed. If the float switch is closed and the icemaker will not switch from the 1-minute fill cycle to the initial harvest cycle, replace the control board.

If open, confirm that the water tank is full. If the tank is not full, check the water supply, water filters, and inlet water valve. If the tank is full, follow the steps in "IV.D.2. Float Switch Cleaning." After cleaning the float switch, check it again. Replace if necessary.

2.Float Switch Cleaning

Depending on local water conditions, scale may build up on the float switch. Scale on the switch can cause the float to stick. In this case, the float switch should be cleaned.

1)Turn off the power supply.

2)Remove the front panel and move the control switch to the "OFF" position.

3)Remove the insulation panel, then remove the cap located on the front bottom part of the ice dropping hole. Drain the water tank.

4)Replace the cap in its correct position. Be careful not to cross thread it.

5) Disconnect the vent tube and the flush	Flush
tube from the top of the float switch, then
remove the float switch assembly from the
mounting bracket and remove the rubber
boot from the bottom of the float switch
assembly. See Fig. 1.

6)Remove the retainer rod from the bottom of the float switch assembly, then remove the float. Be careful not to bend the retainer rod excessively when removing it.
