Troubleshooting 191
Check No. 9 Check for Fan Motor Connector (Signal Line)
For RZP71~140D models
(1) Turn the power supply off.
(2) With the fan motor connector disconnected, measure the resistance between each pin, then
make sure that the resistance is more than the value mentioned in the following table.
Check No. 10 Check for Power Transistor
Judgment according to the continuity check by using an analog tester.
(1) Do not touch the charged area (high voltage) for 10 minutes after turning the power supply
off.
(2) If you must touch such an area, make sure that the power supply voltage of power transistor
is 50 V or less.
(3) Before measuring the continuity, disconnect the connection between compressor and power
transistor.
(4) Measure the continuity in the following procedure.
[Judgment] Normal if the continuity check results in the following.
Power transistor (on inverter PC board)
* If there is continuity, the resistance should be the same as each phase.
* If a digital tester is used for the measurement of continuity, and continuity may be
reversed.
