gray fan blade. However, the white fan blade
should be used as a service replacement if the unit
experiences temperature problems.
On Madison production prior to S/N M815563 the
refrigerator fan motor runs all the time once the
door is closed unless altered during field service
repair.
On Phoenix and Madison production after S/N
815564, the refrigerator fan motor cycles on and

Freezer Air Flow - Models 532, 542, 561
(Figure 3-6)
The cabinet air is drawn in by the fan motor across
the evaporator and then is forced in two directions.
In one direction, the air is forced up the back
channel of the freezer and through the freezer duct
assembly. The air diffuser distributes the air even-
ly throughout the top of the freezer section.
In the other direction, the air is forced into the bot-
tom of the freezer. The heavy cold air cascades
down through the freezer baskets. The fan motor
pulls the air up and across the freezer control and
ice maker, returning to the evaporator coil.
The freezer control senses this return air and shuts
down the compressor and fan motor when the set
temperature is reached.
