• V
erify freezer temperature is 5°F or colder
, and that the airflow is not blocked.
• Make sure that the ice maker is receiving the proper amount of water (8 cubes = 4.4 oz
. (130 cc) of water).
• Look for high ice usage by customer
.
• At 0°F
, 80 to 106 cubes of ice in a 24-hour period is normal.

• V
erify freezer temperature is 5°F or colder
. Ice production will be slow from 10°F to 15°F
, and will stop at around 18°F
.
• Ice maker should be in the “park” (2:00) position.
* V
oltage will be present on the tan wire of the ice maker for 7 to 8 seconds during harvest
just before it reaches the “park”
position. This
voltage is in series with the mold heater
, and will be between 80 and 105 volts ac. The voltage on the t
an wire signals the val
ve to fill the ice
maker
. Line voltage must alway
s be present across the BK & WH wires at the valve. 14 vdc must
always be present across the RD/Y
L
and
BK/YL
wires on the valves.
