Defrost Pre-Chill
¾ After accumulating 96* hours of compressor run time (actual compressor run
time and door openings), the operating system will enter pre-chill.
¾ Pre-chill will occur whether the last freezer defrost was normal or abnormal.
¾ Pre-chill time will vary from 10 to 60* minutes, depending on door openings and
compartment temperatures during pre-chill.
¾ Any compressor run time prior to the beginning of pre-chill does not count in the
pre-chill time.
¾ There is a 6* second delay after the compressor cuts off at the end of pre-chill
before energizing the defrost heaters.
¾ The ice box fan will run at high speed whenever ice box cooling is needed during
the pre-chill cycle.
¾ Pre-chill ends when either the maximum time expires (60 minutes*), evaporator
pre-chill temperatures are met (-30F*) or freezer pre-chill temperatures are met
(-10F*).
(Single and Variable speed compressor)
