the switch shaft can cause the floats to stick. This will
effect the unit operation. In this case, the float switch
should be cleaned and checked.
The float switch is held in place on the top cover by a twist
lock bracket. To remove it, twist the switch flange and lift.
Soak the switch assembly in ice machine cleaner. While it
is not necessary to do so, some technicians remove the
floats from the shaft during cleaning. If you remove them,
note that the blue float is on top. Also it is important to
clearly mark the top of the floats so that they can be re-
placed correctly. (See drawing below). Installing the floats
upside down will effect the timing of the float switch op-
eration. Once clean, rinse and wipe the cleaner off and
check the switch with a good quality ohm meter.
This float switch has three wires (the black wire is com-
mon) and two separate switches. Check the top switch
by ohming out the black and red wires. When the float is up
the switch should be closed. Check the bottom switch by
ohming out the black and blue wires in the same manner. If
either switch fails, the assembly should be replaced.
