Inverter - GE Profile PDCF1NBW Technical Service Manual

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
and the EMI fi lter (if utilized) must be removed to
access the inverter.
To remove the Inverter:
1. Remove the ¼-in. hex-head screw that holds the
water valve and the
holds the EMI fi lter to the cabinet.

2. Carefully pull the water valve and the EMI fi lter
out from the cabinet.
3. Disconnect the 2 wire harnesses to the inverter.
4. 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.

5. Remove the Phillips-head screw from the
inverter.
6. Lift and rotate the inverter counterclockwise.
7. Disconnect the compressor harness from the
compressor terminals.
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. 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.
