Test Cycling: Remove cover by inserting screwdriver in notch at bottom

and prying cover from housing. Use screwdriver to rotate motor gear
counterclockwise until holding switch circuit is completed. All compo­nents of ice maker should function to complete the cycle.

Water Fill Volume: The water fill adjustment screw will change the fill
time. One full turn is equal to 20cc (.68 oz.). The correct fill is 102 to
130cc (3.4 to 4.3 oz.). When a water valve is replaced, the fill volume
must be checked.

IMPORTANT

If any green grounding wires are removed during servicing, they must be returned to their original position and
properly secured.

Service Mode For Perfect Temp™ Drawer

Activation
This mode is accessible only
when the drawer is in OFF
mode. Press and hold the
temperature decrease key
(–) and the temperature in­crease key (+) for 5 seconds.

Deactivation
Press and hold the tempera­ture (+) key for 5 seconds, or
no keys pressed in 5 minutes
returns to the OFF mode of
operation.

Test Operation

The up/down buttons
will be used to navigate
through the tests and the
ON/OFF button will be used
to initiate the displayed test.

Fan Test

Display shows “F1” for fan
on or “F0” for fan off.

Heater Test

Display shows “H1” for heater
ON or “H0” for heater OFF.

Damper Test

Display shows “d1” for
damper open, or “d0”
for damper closed.
Damper movement
may take 30 seconds.

To Test Damper

1. Remove drawer.

2. Start damper test.

3. Observe damper
moving open and
closed.

4. Exit damper test.

Report NTC Temperature
Test

Display shows “b1” for cham­ber sensor
test. The UI display will show
—°F until the main board
responds with associated
sensor temperature reading.

Display Test
