Inverter
The inverter is accessed from the back of the
refrigerator and is located on the left side of the
compressor behind the water valve. The water valve
must be removed to access the inverter.
To remove the Inverter:
Disconnect power to the refrigerator and
remove the back access panel.
Remove the ¼-in. hex-head screw that holds the
water valve to the cabinet, then carefully pull
the water valve out from the cabinet.
Disconnect the 2 wire harnesses to the inverter.
Remove the ¼-in. hex-head screw and the
inverter ground wire from the cabinet.

Note:
The inverter is attached to the compressor
by a lip above the compressor terminals, a
tab (located at the bottom rear corner), and a
Phillips-head screw.

wiring removed for clearer view.
Remove the Phillips-head screw from the
inverter.

WARNING:
When the refrigerator is plugged in, 120
VAC is always present at the inverter.
Note:
Certain voltmeters will not be able to read
voltage output from the inverter. If no voltage or
erratic voltage is measured, it does not necessarily
indicate a faulty inverter.
The inverter receives 120-VAC line-in from the
power supply (black and orange wires). The inverter
converts this single-phase, 60 Hz, 120 VAC into 3-
phase, 230 VAC, with frequency variations between
57 Hz and 104 Hz. This voltage is delivered to the
compressor through 3 lead wires. Each wire will
carry identical voltage and frequency.
Note:
The compressor leads must be connected to
measure voltage output. If the compressor wires are
not connected, or if an open occurs in one of the 3
lead wires or in the compressor, the inverter will stop
voltage output.
When checking inverter voltage output, connect
the test-meter leads to any 2 of the 3 compressor
lead wires at the inverter plug (plug should be
connected). The same reading should be measured
between any 2 of the 3 wires.
Lift and rotate the inverter counterclockwise.
Disconnect the compressor harness from the
compressor terminals.
