COMPRESSOR AND ANOTHER ELECTRIC COMPONENTS
[_ Power Source I
Separate the PTC-STARTER from
the Compressor and measure the
voltage between M and C of the
Compressor.
The applied voltage is not in the
range of Rating Voltage _+10%.

Check the
resistance of the
Compressor Motor.
Test the resistance among
M-C, S-C, and M-S.
Replace the Compressor.

Check the
starting state.
Measure minimum starting voltage
after checking steps 1-3 above.
And measure the pressure balance
of the PTC with the interval of
more than 5 min.
