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.
