ELECTRICAL SYSTEM
The wiring diagram is located in the machine
compartment area.
All electrical components are grounded to the
cabinet.
The green/yellow center conductor in the power
cord is attached to the cabinet to provide a ground
circuit when the cord is plugged into a properly
grounded outlet.
After replacing an electrical component,
always
reconnect the ground wire.
The electrical outlet should be checked to make
sure it is properly wired. Check the outlet with a
circuit tester.
The Compressor
The compressor is a variable speed compressor.
The starting and run speeds are controlled by the
compressor PC board. The compressor terminals
resistance are of equal value. Placing ohm meter
probes on any two terminals of the compressor
should read the same.
Note: There are no overload protector or starting
relay on the terminals of the compressor
every thing is controlled on the PC board.
