DEFROST TIMER — Freezer units built between 1991 and 1997 were equipped with a defrost timer (Fig. 16) preset for four 23 – 25 minute defrost cycles per day (every 6 hours). By inserting a screwdriver into the large hole in the bracket and turning clockwise, the time of day that these cycles occur may be adjusted.
MECHANICAL DEFROST TIMER — (Freezers built from 1997 to 2001) — When power is initially applied to the cabinet, the exterior dial of the defrost time clock (Fig. 17) must be set to the correct time of day.
To access the defrost timer, remove the front trim panel (Fig. 1) by lifting up and out. Open the door on the defrost timer box. Turn the inside knob counterclockwise until the exterior dial is positioned so the correct time of day is at the time of day pointer. Replace the front trim panel when done.
The defrost timer (Fig. 17) is set at the factory for four
If the power supply is interrupted, the defrost timer must be reset to the correct time of day.
