Bridge Diodes converts 115V AC (Alternating current) to 115V DC (Direct current)
The Voltage Multiplying circuit then increases the 115V DC to 230V DC.
Then the IPM (Intelligent Power Module) converts the 230V DC to 230V AC.
The converted AC power can be regulated to any required voltage and frequency.
Measure the voltage at locations on the connector (as shown picture) with a multi-tester.
There are two PCB located behind the PCB cover.
One is the main PCB, and the other is the driver PCB
the linear compressor.

IPM Voltage Check
To ensure proper diagnosis, make sure that the unit
has been plugged in for at least 10 min.
To determine if the compressor is receiving the
proper voltage, check the PCB output voltage
during operation.
Normal operating voltage will be between 80V AC
and 180V AC.
Note : Higher voltage readings may occur under
“heavy” load conditions.
