Fresh Food Only Heated Defrost
Fresh food only heated defrost occurs after 32* hours of compressor run time.
Fresh food only heated defrost does not use a pre-chill cycle.
Door openings are factored into the compressor run time.
1 second door opening = 100 seconds of compressor run time*
Providing previous freezer or fresh food only heated defrost cycles were
normal the freezer will defrost every 3 fresh food defrost.
