Before calling a service provider try the trouble shooting sugges-
tions below.

Ice Machine Operation

Ice machine does not operate
Is the ice machine's power cord plugged in? Plug the power
cord into a grounded 3 prong outlet.
Is the selector switch in the front grille set to the "ON" posi-
tion? Check the switch to be sure it is in the "ON" position.
Is a fuse blown or a circuit breaker been tripped? Replace a
blown fuse or reset a tripped circuit breaker.
Is the temperature of the room cooler than it normally is? The
minimum room temperature is 55°F (13°C). The bin thermistor
may be sensing the room temperature and shut off before the
bin is full of ice. If the room temperature remains low the ice
machine may not restart.
Is there a drain pump in the ice machine? If a large amount of
water was added to the ice machine then you should wait a few
minutes for the drain pump to dispose of it. If there is still water
in the ice bin check the drain pump vent line and drain line for
obstructions or kinking.
The ice machine is noisy
Many sounds of an ice machine are different than your house-
hold refrigerator. This subject is discussed on page 17, but check
the following:
Do you hear water being circulated in the ice machine? This is
a normal sound as water is added once every ice making cycle.
Is there a "whoosing" sound? Make sure water is getting to
the ice machine. Also check to make sure the drain plug is fully
seated in the water reservoir.
Is there an ice slab caught between the evaporator plate and
the grid cutter? First check to see if the ice machine is level. If
the ice machine is level run a cleaning cycle.
Ice Production
Little or no ice production from the ice machine
Is the selector switch set to the "ON" position? Check the
switch to be sure it is in the "ON" position.
Is water getting to the ice machine? Make sure nothing is
disrupting the water supply such as a closed water valve or a
blown fuse or tripped circuit breaker.
Has the ice machine just been started? A typical ice production
cycle can take up to 11/2 hours. Initial start up cycles can take
longer. Check the ice machine after 24 hours for ice accumula-
tion in the bin.

TROUBLESHOOTING GUIDE

Is the reservoir drain plug in place? Check that the reservoir
drain plug is properly seated.
Is the water distributor tube restricted? Run a cleaning cycle to
clean the ice machine. Also check any filters to make sure they
are not restricted.
Is the condenser fan air flow restricted? Make sure the grille in
the front of the ice machine is open for proper air circulation.
Is the room and/or water temperature to warm? Move the ice
machine to an area where the ambient temperature is below
90°F (32°C). The ice machine should not be placed next to a
heat source such as an oven. Check the cold water connection.
Is there scale build up in the ice machine? If there is scale build
up on the evaporator, the ice machine needs to be cleaned. See
"Cleaning the Ice machine".

Ice Quality

Odor, grey color, or off taste in the ice
Is there mineral scale build up on the evaporator plate? The
ice machine needs cleaning. See "Cleaning the Ice Machine".
Is there a high mineral content in the water? The water may
need to be filtered.
Are food items being stored in the ice bin? Remove food from
the ice bin.
Clumps of ice
Are there clumps of ice in the bin? If the ice isn't used on a
regular basis it will melt and form into clumps. Break up the ice
clumps with the ice scoop.
Ice cubes are too big, too small, or hollow
Is there low ice consumption? Ice is slowly melting in the
ice bin which will affect the size of the cubes. This is normal
operation. When the ice bin needs to be replenished, cubes will
return to the regular size.
Is the ice slab releasing? Clean the evaporator. See "Cleaning
the Ice Machine".
Is the distributor tube restricted? Check the water line to the
ice machine to make sure there are no restrictions or kinks in
the line. Check all filters to make sure they are not restricted.
Check that the water flows evenly out of the distributor tube, if
not, clean the ice machine. See "Cleaning the Ice Machine".
