Step 1 – Check the compressor windings resistance.
•
With the refrigerator disconnected from the power supply, remove the compressor cover and unplug the fusite
terminal connection from the compressor.
•
Select the Ohms range on the multi-meter and measure the resistance of all three windings. The
resistance should be the same across all three windings. Refer to winding resistances in compressor
specifications, Sections 1.3, 1.4 and 1.5.
•
Check for leakage to ground from the windings within the compressor.
•
Reconnect the fusite plug to the compressor and refit the compressor cover.
Step 2 – Check the input voltage to the inverter.
•
Remove the protective terminal cover from the inverter, reconnect the appliance to the power supply and
set the compressor running.
•
Select the multi-meter to measure AC volts. With the probes measure the input voltage as shown at the
two terminals indicated or at the input harness edge connector.
A normal cabinet with no fault:
•
Will measure mains voltage (110volts or 230volts) AC input into the inverter.
•
The compressor will be running (this can be felt by placing a hand on the compressor shell).
•
The LED on the inverter board will be flashing once every 15 seconds as all is normal.
