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.
Freezer Compartment Theory of Operation
As a freezer thermistor warm, the resistance decreases allowing low voltage signal to be sent to electronic
control. Electronic control sends two low voltage signals, one to the compressor relay coil (C1) and one
to the evaporator relay coil (E1).
When both relay coils are energized and both relay contacts are closed, high voltage circuits to evaporator
fan motor and compressor / condenser fan motor are complete.
As thermistor cools during refrigeration cycle, resistance through thermistor increases blocking low
voltage signal to electronic control interrupting circuit.
