Troubleshooting
&DXWLRQ
Be sure to turn off power switch before connect or disconnect connector, or
else parts damage may be occurred.
Check the IPM module method:
Disconnect the compressor harness connector from the outdoor unit PCB.
To disengage the connector, press the protrusion on the connector.
Then, to measure resistance between P (+) andN (-) and the U, V and W terminals of the
compressor connector with a multi-tester. Evaluate the measurement results for a pass/fail judgment.
N(-)terminal of tester(P(+)for digital tester) P(+) UVW P(-) UVW
P(+)terminal of tester(N(-)for digital tester) UVW P(+) UVW P(-)
Normal resistance
Several k to several M (и)
Unacceptable resistance Short (0 ) or open
Turn off the power.check if the
compressor wiring commect.
NO
Check the IPM module
Renewedly connect the wiring
Yes
Normal?
Yes
NO
Change the IPM module
Test the resistance values among
Phases U, V and W of compressor
If the resistance are
equal and less than 3ȍ
NO
Replace the compressor
Yes
Check the installation condition.
