Diagrammatic Overview Function Description
The electronic system consists of several parts:
Power/control module, display module, compressor, defrost heater, low ambient heater, door flapper heater,
produce compartment fan, freezer compartment fan, light, temperature sensors, icemaker sensors,
solenoids and door sensors.
The purpose of the power/control module is to turn on the compressor, which cools the evaporator, then to
use the fans to efficiently cool the compartments. Both fans turn on with the compressor. The freezer
compartment (FC) fan is kept at a constant speed while the produce compartment (PC) fan is regulated to
provide the balanced cooling for both compartments. The function of the microprocessor in the
power/control module is to provide independence of both compartments to their set temperatures, although
the environment of one compartment effects the other as they are linked by the ducts as can seen by the
internal air flow of the cabinet. (Refer to diagrams 4.2, 4.2.2A and 4.2.2B).
