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 26-minute
defrost cycles per day (2
AM, 8 AM, 2 PM and 8 PM). Depending on
local conditions, it may be necessary to change the frequency or
duration of defrost cycles.
If the power supply is interrupted, the defrost timer must be reset
to the correct time of day.
