Electronic Function Description
WARNING: To avoid electrical shock which can cause severe personal injury or death,
disconnect power to refrigerator using power switch before servicing. Wires removed
during disassembly must be replaced on proper terminals to insure correct grounding
and polarization. After servicing, reconnect power using power switch.
Refrigeration Compartment Theory of Operation
As fresh food thermistor warms, resistance decreases allowing low voltage signal to be sent to the
electronic control. Electronic control sends a low voltage signal, to semiconductor switch for DC fresh
food fan and DC condensate evaporator fan.
Both fans begin operating. Fresh food fan circulates freezer air into fresh food compartment. Condensate
evaporator fan circuilates air over condensate drain pan aiding in evaporation.
As fresh food thermistor cools, resistance increases blocking low voltage signal to electronic control
interrupting circuit to DC fresh food fan and DC condensate evaporation fan.
