The freezer defrost timer is preset for three
defrost cycles every 24 hours. To add and/or
change defrost times:
1. Remove the pins from the outer (large)
dial.
2. Insert the pins into the desired time slots.

operational periods between defrosts.

ADJUSTING DEFROST SAFETY
TERMINATION
The defrost cycle is normally terminated by a
thermodisc. It is automatically terminated if a
system malfunction occurs.
The backup defrost termination is preset at the
factory for a 30-minute defrost cycle.
Normally, no adjustment is needed.
The backup safety defrost length can be reset
by pressing down on the inner pointer and
rotating until it is aligned with the desired
safety time.
