REFRIGERATOR/FREEZER COMBO DEFROST CYCLE
The defrost cycle starts after ten hours of
compressor run time.
The condenser fan runs for two minutes after
the compressor stops and the heat starts.
The evaporator fans stop immediately.
The heater is energized until the defrost sen-
sor (top center of the evaporator) reaches
8F. (There is no set defrost time.)
A defrost thermal fuse, located in the right
end of the evaporator return cuts out if an
overheat condition occurs.
There is a 5-minute drip time after the defrost
heat is terminated by the defrost sensor.
The condenser fan starts when the heat
stops and runs throughout 5-minute drip
time.
At the end of the 5-minute drip time, the
compressor starts.
One minute after the compressor starts, the
evaporator fans start.
Count down to the next 10 hours of compres-
sor run time begins, and so forth.
