Inverter - GE PSH23PGR Series Technical Service Manual

Inverter

• The inverter is accessed from the back of the
refrigerator.
• It is located on the left side of the compressor
behind the water valve.
• The water valve must be removed to access
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. 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.
