2. Float Switch Cleaning
Depending on local water conditions, scale may build up on FS. Scale on the switch can
cause the oat to stick. In this case, FS should be cleaned.
1) Remove the louver, move the control switch to the "OFF" position, then unplug the
icemaker from the electrical outlet.
2) Disconnect the silicone hose to drain the water, then after all the water has drained
reconnect the silicone hose back in its correct position. See Fig. 4.
3) Remove the top and upper rear panels.
4) Disconnect the FS/CB 2-pin connector (1 black (BK) wire and 1 red (R) wire coming
from FS and 2 red (R) wires coming from CB K1 connector pins 1 and 3).
