FREEZER ICE MAKER INFORMATION
(Where Applicable)
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
Adjustment
All electrical parts and wiring must be shielded from torch flame. DO NOT allow torch
to touch insulation; it will char at 200°F and flash ignite (burn) at 500°F. Excessive
heat will distort the plastic liner.
Press + for up to 10 sec. Diagnostic Mode will automatically deactivate after 5 min. of inactivity.
Note: Silence alarm.
