If the control board light does not respond to the float,
proceed with Step 1 below.
1. Disconnect power to the ice machine and pull the
float switch and connector through the ice machine
base and disconnect.
2. Attach an ohm meter lead to each float switch wire.
3. Place the float in the down position - The float switch
must be closed.
4. Place the float in the up position - The float switch
must be open.
5. If the float tests good, ohm the interconnecting wires
to the control board and inspect connectors.
NOTE: Make adjustments with the ice machine in the off
position. Making adjustments during the freeze cycle may
produce an initial sheet of ice that is thicker than future
cycles.
