ICE MAKER OPERATION
When the ice bucket is full, the ice making mechanism will
shut off. However, the refrigeration system will continue
to cool and maintain the ice supply.
NOTICE
Do not place cans or bottles in the ice
compartment because they will freeze.
To turn off ice production: Raise the bin arm into
an upright and locked position. The unit will preserve
temperature for ice storage.
NOTICE
If not intending to use the ice maker, turn the
water supply valve off. It is also important to
raise the bin arm of the ice maker (see above).
Failure to raise the bin arm may result in damage
to the water valve.
Certain sounds are normal during the unit’s operation. You
may hear the compressor or fan motor, the water valve,
or ice dropping into the ice bucket.
CAUTION
!
NEVER use an ice pick, knife or other sharp
instrument to separate cubes. Shake the ice
bucket instead.
During periods of limited use or high ambient
temperatures, it is common for cubes to fuse together.
Gently shake the bucket to break apart cubes. If not using
the ice maker regularly, empty the ice bucket periodically
to ensure fresh cubes.
It is normal for cubes to appear cloudy. The cause is air
trapped in the water because of fast freezing. It is not
caused by the health, taste or chemical make up of the
water. It is the same air that is in every glass of water you
drink.
Remove the ice bucket for emptying and cleaning. To
remove the ice bucket, raise the bin arm and remove the
bucket from the ice compartment. Use the ice bucket for
ice storage only.

2. Find the adjusting screw on the ice maker assembly
control box (2). The adjusting screw is just below the
minus (-) and plus (+) signs on the control box.
CAUTION
!
Too large of an adjustment to the screw can
cause the water to overflow the ice maker and
can cause property damage.
3. Turn the adjusting screw toward the minus (-) sign
(clockwise) for smaller cubes or toward the plus (+)
sign (counterclockwise) for larger cubes.
4. Install the ice maker assembly cover.

These temperature controls are double throw, single pole
controls. The sensing tube is inserted into the ice maker mold
and senses mold temperature. After ice is sensed in the
mold, the 2-3 contacts open (stopping the compressor) and
the 2-1 contacts are closed (starting the ice maker motor).
The 2-3 contacts close (2-1 contacts open) before the end of
the ice harvest cycle.The hold switch prevents power going
back to the compressor. This prepares the control for the next
cycle.

Defrost
This unit requires manual defrost, periodically.
Inspect the interior walls for frost build up every 3 - 4
weeks. Defrost your unit when 1/4” of frost builds up
on the interior walls. Frost will build up faster in humid
environments and when the door is opened frequently.
To defrost, remove ice bucket, turn o unit, leave door
open, and allow frost/ice to melt naturally. Do not use
tools to chip or scrape the frost as it may damage your
unit. Use a towel to absorb melting frost/ice. Before
turning the unit back on, make sure all the frost is gone
and the unit is dry.
