¾ When cooling is required, the main control board moves the 3-way valve to
either ‘A’ position (supplying refrigerant to both fresh food and freezer
evaporators) or ‘B’ position (supplying only the freezer evaporator), depending
upon compartment temperatures.
¾ The compressor and fan(s) are delayed for 3* minutes before restarting.
¾ The compressor will start at high speed for 1 minute, then may change speeds
depending upon the temperature of both the fresh food and freezer.
¾ When only the fresh food temperature is satisfied, the 3-way valve will move to
the ‘B’ position (supplying only the freezer evaporator) to continue cooling the
freezer. Fresh food cycle defrost will begin.
¾ When the freezer and fresh food temperatures are satisfied, the compressor
and fans will turn off. The 3-way valve will move to the ‘D’ position, shutting off
refrigerant flow to both evaporators to reduce refrigerant sounds.
¾ After the accumulated compressor run time (including door openings) has been
reached, the unit will begin the defrost pre-chill cycle.
( 1 second of door opening = 100 seconds of compressor run time*)
