Electronic Functional Description
Freezer Compartment
As freezer thermistor warms the resistance decreases
allowing low voltage signal to be sent to electronic
control. Electronic control send two low voltage
signals, one to the compressor relay coil (C1) and one
to the evaporator fan 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.
To avoid electrical shock which can cause severe personal injury or death, disconnect power to refrigerator using
power switch before servicing. Discharge capacitors through a resistor before handling. Wires removed during
disassembly must be replaced on proper terminals to insure correct earthing and polarization. After servicing,
reconnect power using power switch.
WARNING
230 VAC
