D. Float Switch Check and Cleaning
F/S is used to determine that there is sufficient water in the water tank after the 1-minute
fill cycle and after each harvest cycle. F/S is also used to determine that the appropriate
volume of water has been converted into ice before switching out of the freeze cycle. No
adjustment is required.

7) Check for continuity across F/S leads. With the water tank empty, F/S should be open.
If open, continue to step 8. If closed, follow the steps in "IV.D.2. Float Switch Cleaning."
After cleaning F/S, check it again. Replace if necessary.

8) Reconnect the black F/S connector to CB 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, F/S is good and the check is complete. If the initial harvest cycle
does not begin, continue to step 10.

F/S is closed and the icemaker will not switch from the 1-minute fill cycle to the initial
harvest cycle, replace CB.
If open, confirm that the water tank is full. If the water tank is not full, check the water
supply, water filters, and WV. If the water tank is full, follow the steps in "IV.D.2. Float
Switch Cleaning." After cleaning F/S, check it again. Replace if necessary.
