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
ll 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.
1. Float Switch Check
To check F/S, follow the steps below.
1) Turn off the power supply.
2) Remove the front panel.
3) Place the control switch in the "SERVICE" position. Then place the service switch in the
"DRAIN" position.
4) Replace the front panel in its correct position, then turn on the power supply for
2minutes.
5) Turn off the power supply.
6) Remove the front panel, then move the control switch to the "OFF" position.
7) Remove the top and right side panels.
8) Remove the control box cover, then disconnect F/S connector from CB K5 (black)
connector.
9) Check for continuity across F/S leads. With the water tank empty, F/S should be open. If
open, continue to step 10. If closed, follow the steps in "IV.D.2. Float Switch Cleaning."
After cleaning F/S, check it again. Replace if necessary.
10) Reconnect F/S connector to CB K5 (black) connector, then replace the control box
cover, right side, and top panels in their correct positions.
11) Move the control switch to "ICE" position. Replace the front panel.
12) Turn on the power supply.
13) As water lls the water tank, F/S contacts should close. After 1 minute, the 1-minute ll
cycle should end and the initial harvest cycle should begin.
14) Once the harvest cycle starts, turn off the power supply.
15) Remove the front panel, then move the control switch to the "OFF" position.
16) Remove the top and right side panels.
17) Remove the control box cover, then disconnect F/S connector from CB K5 (black)
connector.
18) Check for continuity across F/S leads. With the water tank full, F/S should be closed. If
F/S is closed and the icemaker will not switch from the 1-minute ll cycle to the initial
harvest cycle, replace CB.
19) If open, conrm that the water tank is full. If the water tank is not full, check the water
supply, water lters, and ll/rell water valve. 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.
